Let's analyze this step by step:
When H2 reacts with each gas:
Looking at the properties of all products:
The only property that applies to ALL products is that they are all more water-soluble than their reactants due to their polar nature.
{"correct_answer_key":"c"}
This question is about the properties of products formed when H2 gas reacts with N2, O2, F2, and Cl2 gases under appropriate conditions.
When H2 reacts with:
Looking at these products:
The correct answer is option B, as both NH3 and HF (two of the four products) can form hydrogen bonds.
{"correct_answer_key":"b"}
The question is in Thai. Let me translate it to English:
"Four containers contain gases N2, O2, F2, and Cl2, one type in each container. If H2 gas is allowed to react with the gas in each container under appropriate conditions until products are formed, which of the following is true for the products in all 4 containers?"
Options: a) "The products are gases at room temperature." b) "The products can form hydrogen bonds." c) "The products are more soluble in water than the reactants." d) "The bonds in the products are polar, but the products are non-polar." e) "The products dissolve in water to give acidic solutions."
Now, let's analyze the reactions of H2 with each gas and their products:
Let's check each option:
a) "The products are gases at room temperature."
b) "The products can form hydrogen bonds."
Wait, let me revisit this. Hydrogen bonds form between H and highly electronegative elements (F, O, N). In HCl, Cl is electronegative, but not as much as F, O, or N. Some sources might consider it capable of weak hydrogen bonding, but it's generally not classified as a hydrogen bond former. Let me reconsider this.
c) "The products are more soluble in water than the reactants."
d) "The bonds in the products are polar, but the products are non-polar."
e) "The products dissolve in water to give acidic solutions."
Based on this analysis, option c) "The products are more soluble in water than the reactants" seems to be the correct answer. However, let me double-check my work.
Actually, let's re-evaluate the reactions:
I need to ensure that these reactions can actually occur under reasonable conditions, and that I'm considering the correct products.
For the first reaction, H2 + N2 → 2NH3, this is the Haber process, which requires high temperatures, high pressures, and a catalyst. It's not a direct reaction that would occur spontaneously when mixing H2 and N2.
The second reaction, 2H2 + O2 → 2H2O, is the combustion of hydrogen, which will occur (potentially explosively) if there's an ignition source.
The third and fourth reactions, H2 + F2 → 2HF and H2 + Cl2 → 2HCl, are direct reactions that can occur.
Given that the question specifies "under appropriate conditions," I'll assume that all these reactions can occur as written.
Now, let's reevaluate option c) "The products are more soluble in water than the reactants."
Indeed, for all reactions, the products are more soluble in water than the reactants. So, option c) seems to be the correct answer.
But let me double-check the other options again:
a) "The products are gases at room temperature."
b) "The products can form hydrogen bonds."
d) "The bonds in the products are polar, but the products are non-polar."
e) "The products dissolve in water to give acidic solutions."
After rechecking all options, option c) "The products are more soluble in water than the reactants" is the correct answer.
Actually, let's think about this more carefully.
Option (c) is "The products are more soluble in water than the reactants."
Let's evaluate again:
N2 + 3H2 → 2NH3
O2 + 2H2 → 2H2O
F2 + H2 → 2HF
Cl2 + H2 → 2HCl
Given that the option doesn't apply meaningfully to the O2 + H2 → 2H2O reaction, option (c) might not be the correct answer.
Let's reconsider option (a): "The products are gases at room temperature."
Since H2O is definitely a liquid at room temperature, and HF might be a liquid at the higher end of room temperature, option (a) is not true for all products.
Let me check again all the options for each answer.
(b) "The products can form hydrogen bonds."
(d) "The bonds in the products are polar, but the products are non-polar."
(e) "The products dissolve in water to give acidic solutions."
So options (a), (b), (d), and (e) are all false. Let me reconsider option (c) again.
(c) "The products are more soluble in water than the reactants."
The issue is with the O2 + H2 → H2O reaction, where the product is water itself. It's not meaningful to say water is "soluble" in water. It's misleading to say the product (H2O) is "more soluble in water" than the reactants (O2 and H2) because the product is water itself.
So, option (c) doesn't accurately describe the situation for all four reactions. Hence, it seems like all the options (a) through (e) have issues.
Let's take another approach. The question asks which is TRUE for the products in all four containers. Let's re-evaluate each option with the correct products.
Actually, I'm forgetting that the original reactions (if the starting material in each container is N2, O2, F2, or Cl2, and if we add H2 to each) would be:
Let's reconsider option (c) "The products are more soluble in water than the reactants."
For all four reactions, it appears that the products are indeed more soluble in water than the reactants, even though the comparison for H2O vs O2 is a bit unusual.
Actually, for reaction 2, both the reactants (H2 and O2) are gases with low solubility in water. The product (H2O) is water itself. So it's not appropriate to compare the solubility of "H2O in water" with the solubility of "H2 in water" and "O2 in water" because H2O is water.
Re-considering the question and the wording of option (c), it specifically asks for a comparison between the products and reactants in terms of solubility. While it's true that H2O "dissolves" in water better than O2 (since it's already water), the phrasing is awkward and might not be the intended interpretation.
Let me revisit the other options to see if there's a better fit.
Actually, I think there's a serious translation issue here. Let me re-examine option (c) in the context of the problem.
The question states that there are 4 containers, each with a different gas: N2, O2, F2, and Cl2. When H2 is added to each container and allowed to react, we get the following products:
Option (c) states "The products are more soluble in water than the reactants."
For reaction 2, the reactants are H2 and O2, while the product is H2O. If we try to dissolve each in water, H2 and O2 have low solubility, while H2O is already water. So, it doesn't make sense to say "H2O is more soluble in water than H2 and O2" because water doesn't dissolve in water; it is water.
Given this issue with reaction 2, option (c) doesn't seem to be the correct answer because it doesn't hold for all four reactions.
Let me re-examine options (a), (b), (d), and (e):
(a) "The products are gases at room temperature."
(b) "The products can form hydrogen bonds."
Given that Cl has the same electronegativity as N, and N can participate in hydrogen bonding, it's possible that Cl can also participate in hydrogen bonding to some extent, especially in HCl. However, the question is whether HCl can form hydrogen bonds with other molecules. In solution, HCl typically dissociates to form H+ and Cl-, and the H+ ion can form hydrogen bonds with water molecules. But the question asks about the properties of the product itself, not its behavior in solution. Pure HCl doesn't form hydrogen bonds with itself in the way that NH3, H2O, and HF do. So, option (b) is still false.
I've been thinking more about this. The ability to form hydrogen bonds is primarily determined by having a hydrogen atom bonded to a highly electronegative atom (like F, O, or N). HCl has a hydrogen atom bonded to Cl, which is electronegative, but not as electronegative as F, O, or N. However, the difference in electronegativity between H and Cl is substantial, leading to a polar bond where the hydrogen has a partial positive charge. This can potentially allow HCl to form weak hydrogen bonds with other polar molecules.
However, the generally accepted definition of hydrogen bonding restricts it to the interaction between a hydrogen atom bonded to F, O, or N (the donor) and an electronegative atom (the acceptor). Given this definition, HCl is typically not considered to form hydrogen bonds.
So, since HCl doesn't form hydrogen bonds, option (b) is still false.
(d) "The bonds in the products are polar, but the products are non-polar."
(e) "The products dissolve in water to give acidic solutions."
It seems like all five options have issues. However, if I were to choose the most accurate among them, and considering that the question might have translation issues, my best guess would be option (c). While the comparison for H2O vs. O2 is unconventional, H2O is infinitely "soluble" in water compared to O2's limited solubility. For the other three reactions, the products are indeed more soluble in water than the reactants, making option (c) the most accurate.
Actually, let's try to imagine what the question is asking a bit differently. Maybe it's asking about the relative water solubilities of the reactants vs the products:
N2 has very low solubility in water. NH3 is highly soluble in water.
H2 and O2 have very low solubility in water. H2O is fully miscible with water (it is water).
F2 reacts with water rather than dissolving, but if we were to measure equilibrium solubility before reaction, it would be low. HF is fully miscible with water.
Cl2 has limited solubility in water. HCl is fully miscible with water.
So in all cases, the products are more "water-compatible" than the reactants. This might be what option (c) is trying to convey.
Overall, among the given options, (c) seems to be the best fit, despite the awkward phrasing for the comparison of H2O and O2 in terms of water solubility.
Let me double-check the others one more time: (a) False because H2O is a liquid at room temperature. (b) False because HCl doesn't form hydrogen bonds. (c) True if we interpret it as the products having greater water compatibility than the reactants. (d) False because all products are polar. (e) False because NH3 gives a basic solution and H2O is neutral.
Given the analysis, I believe the correct answer is (c): "The products are more soluble in water than the reactants."
Looking at the question, I need to identify what happens when H2 reacts with each of the 4 gases (N2, O2, F2, Cl2) under appropriate conditions.
The reactions produce:
Analyzing each option:
{"correct_answer_key":"c"}
To determine the correct answer, let's analyze the reactions of hydrogen gas (H₂) with each of the gases in the containers (N₂, O₂, F₂, Cl₂) under suitable conditions:
H₂ + N₂: Under normal conditions, nitrogen and hydrogen do not react significantly without a catalyst and high pressure (Haber process). However, if they do react, they form ammonia (NH₃), which is a gas at room temperature but can dissolve in water to form a basic solution (not acidic).
H₂ + O₂: Hydrogen reacts with oxygen to form water (H₂O), which is a liquid at room temperature and dissolves in water trivially. Water is neutral, not acidic.
H₂ + F₂: Hydrogen reacts vigorously with fluorine to form hydrogen fluoride (HF), which is a gas at room temperature. HF dissolves in water to form hydrofluoric acid, a weak acid.
H₂ + Cl₂: Hydrogen reacts with chlorine to form hydrogen chloride (HCl), which is a gas at room temperature. HCl dissolves in water to form hydrochloric acid, a strong acid.
Now, let's evaluate the options:
a. ผลิตภัณฑ์เป็นแก๊สที่อุณหภูมิห้อง:
b. ผลิตภัณฑ์เกิดพันธะไฮโดรเจนได้:
c. ผลิตภัณฑ์ละลายน้ำ ได้ดีกว่าสารตั้งต้น:
d. พันธะในผลิตภัณฑ์มีความเป็นขั้ว แต่เป็นสารไม่มีขั้ว:
e. ผลิตภัณฑ์ละลายนําแล้วให้สารละลายมีสมบัติเป็นกรด:
The most accurate and universally true statement among the options is:
{"correct_answer_key":"b"}
The question describes four containers, each containing one of the gases: N₂, O₂, F₂, Cl₂. When H₂ reacts with each of these gases under appropriate conditions, the following products are formed:
Now, let's analyze the options:
(a) "Products are gases at room temperature" → False
(b) "Products can form hydrogen bonds" → True
(c) "Products dissolve in water better than the reactants" → True
(d) "Bonds in the products are polar, but the molecules are nonpolar" → False
(e) "Products dissolve in water to give acidic solutions" → Partially True
The most universally correct statement is (c), as all products (NH₃, H₂O, HF, HCl) dissolve in water much better than their reactant gases (N₂, O₂, F₂, Cl₂).
{"correct_answer_key":"c"}
Okay, let's tackle this chemistry problem. So, the question is about four containers each holding a different gas: N2, O2, F2, and Cl2. Then we add H2 to each under suitable conditions to react. We need to determine which of the options a to e is true regarding the products in all four containers.
First, I need to recall the reactions between H2 and each of these gases. Let's go through each one:
N2 + H2: Under high pressure and temperature, usually with a catalyst like iron, they form ammonia (NH3). NH3 is a gas at room temperature. It can form hydrogen bonds because it has N-H bonds. It's also polar and dissolves well in water, making a basic solution.
O2 + H2: When they react, especially with a spark, they form water (H2O). Water is a liquid at room temperature, not a gas. It definitely forms hydrogen bonds (O-H bonds). It's polar and dissolves many substances. When dissolved, pure water is neutral, but if there's something else, maybe acidic or basic, but pure H2O is neutral.
F2 + H2: These react explosively to form hydrogen fluoride (HF). HF is a gas at room temperature but has a high boiling point compared to other hydrogen halides. It can form hydrogen bonds (F-H). It's polar and when dissolved in water, it's a weak acid. So HF solution is acidic.
Cl2 + H2: They react in light (photochemical reaction) to form HCl. HCl is a gas at room temperature but when dissolved in water, it becomes hydrochloric acid, a strong acid. HCl in gaseous state is polar but the molecule itself is diatomic and linear, so maybe the bond is polar but the molecule as a whole? Wait, HCl is a polar molecule because of the difference in electronegativity. But when dissolved, it dissociates into H+ and Cl-, making the solution acidic.
Now, looking at the options:
a) Products are gases at room temperature. Let's check each product:
b) Products can form hydrogen bonds. Let's see:
c) Products dissolve in water better than the reactants. Let's check:
N2 is reactant, product is NH3. NH3 is more soluble than N2. Correct.
O2 and H2 reacting to form H2O. H2O is a liquid, so it's not a matter of dissolving but the product is a liquid. However, the question says "products dissolve in water better than the starting materials". Wait, the starting materials are O2 and H2, which are gases with low solubility. The product is H2O, which is a liquid. If we consider H2O dissolving in water, it's miscible. So yes, H2O dissolves better than O2 and H2. So c is correct for all four. But wait, HCl is a gas, but when dissolved in water, it's very soluble. Cl2 is not very soluble. So HCl dissolves better than Cl2. So yes, all four products dissolve better. So option c might be correct. But let's check other options.
d) The bonds in the products are polar but the molecules are non-polar. Let's see:
NH3: polar bonds (N-H), and the molecule is polar (trigonal pyramidal). So this doesn't fit.
H2O: polar bonds, polar molecule. So no.
HF: polar bond, polar molecule (linear, but very polar). So no.
HCl: polar bond, polar molecule. So none of the products have non-polar molecules. So option d is incorrect.
e) Products dissolve in water to give acidic solutions. Let's check:
NH3 dissolves to form a weak base (ammonia solution is basic). So this is not acidic. Therefore, option e is incorrect because NH3's solution is basic, not acidic. So e is wrong.
So the correct answer is c: products dissolve in water better than the starting materials. All four products (NH3, H2O, HF, HCl) are more soluble in water than their respective reactants (N2, O2, F2, Cl2 and H2). Even though H2O is a liquid, when considering solubility, it's infinitely soluble in itself, which is better than the gases O2 and H2. So option c is correct.
{"correct_answer_key":"c"}
Explanation:
When H₂ reacts with each gas (N₂, O₂, F₂, Cl₂) under suitable conditions, the products are NH₃, H₂O, HF, and HCl, respectively.
Other options fail because:
Thus, c is the correct answer.
This question, written in Thai, asks about the products formed when H₂ gas reacts with four containers each containing N₂, O₂, F₂, and Cl₂ respectively, under appropriate conditions. Let's translate and analyze the options:
Question: Four containers contain N₂, O₂, F₂, and Cl₂ gases, one type per container. If H₂ gas is reacted with the gas in each container under appropriate conditions until a product is formed, which statement is true for the products in all 4 containers?
(a) ผลิตภัณฑ์เป็นแก๊สที่อุณหภูมิห้อง (The product is a gas at room temperature): NH₃ is a gas, but H₂O is a liquid, HF and HCl are gases. So, this is false.
(b) ผลิตภัณฑ์เกิดพันธะไฮโดรเจนได้ (The product can form hydrogen bonds): NH₃, H₂O, and HF can form hydrogen bonds, but HCl cannot (or very weakly). So, this is false.
(c) ผลิตภัณฑ์ละลายน้ำ ได้ดีกว่าสารตั้งต้น (The product dissolves in water better than the reactants): This is generally true. N₂, O₂, F₂, and Cl₂ are not very soluble in water, while NH₃, H₂O, HF, and HCl are highly soluble.
(d) พันธะในผลิตภัณฑ์มีความเป็นขั้ว แต่เป็นสารไม่มีขั้ว (The bonds in the product are polar, but the substance is nonpolar): This is contradictory and false. If the bonds are polar, the molecule can be nonpolar only if the polarities cancel out due to symmetry, which isn't the case here.
(e) ผลิตภัณฑ์ละลายนําแล้วให้สารละลายมีสมบัติเป็นกรด (The product dissolves in water and gives a solution with acidic properties): NH₃ forms a basic solution, H₂O is neutral, while HF and HCl form acidic solutions. So, this is false.
Therefore, the correct answer is C.

The question is: "ภาชนะ 4 ใบ บรรจุแก๊ส N2, O2, F2, Cl2 ใบละชนิด หากนำแก๊ส H2 มาทำปฏิกิริยา กับแก๊สในภาชนะแต่ละใบ ภายใต้เงื่อนไขที่เหมาะสม จนเกิดผลิตภัณฑ์ ข้อใดเป็นจริง สำหรับผลิตภัณฑ์ในภาชนะทั้ง 4 ใบ"

I need to determine the reactions between H2 and each gas: N2, O2, F2, Cl2.
H2 + N2: This forms ammonia (NH3) under the Haber process: N2 + 3H2 → 2NH3
H2 + O2: This forms water: 2H2 + O2 → 2H2O
H2 + F2: This forms hydrogen fluoride: H2 + F2 → 2HF
H2 + Cl2: This forms hydrogen chloride: H2 + Cl2 → 2HCl

Now, evaluate each option for all these products: NH3, H2O, HF, HCl.
a: Are all products gases at room temperature?
NH3: Gas at room temperature
H2O: Liquid at room temperature
HF: Gas, but it has a boiling point around 19.5°C, so at room temperature (say 25°C), it's a gas.
HCl: Gas at room temperature
H2O is liquid, so not all are gases. Therefore, a is false.
b: Can the products form hydrogen bonds?
NH3: Yes, it has N-H bonds and can form hydrogen bonds.
H2O: Yes, it forms hydrogen bonds.
HF: Yes, it forms hydrogen bonds.
HCl: No, HCl is a polar molecule but hydrogen bonding typically requires H bonded to N, O, or F with another electronegative atom. HCl does not form hydrogen bonds; it's just dipole-dipole.
HCl does not form hydrogen bonds because Cl is not electronegative enough in this context. Standardly, hydrogen bonding is for H-F, H-O, H-N.
So, NH3, H2O, HF can form hydrogen bonds, but HCl cannot. Therefore, not all products can form hydrogen bonds. b is false.
c: Do the products dissolve in water better than the starting materials?
Starting materials: N2, O2, F2, Cl2 – these are all gases and generally not very soluble in water.
Products:
NH3: Very soluble in water.
H2O: It's water, so infinitely soluble.
HF: Soluble in water.
HCl: Very soluble in water (forms hydrochloric acid).
Compared to starting materials, which have low solubility, yes, all products are more soluble in water than their respective starting gases.
For N2: NH3 is more soluble than N2.
For O2: H2O is the solvent itself, so infinitely more soluble.
For F2: F2 is slightly soluble, but HF is highly soluble.
For Cl2: Cl2 is somewhat soluble, but HCl is much more soluble.
So, yes, all products dissolve better in water than the starting materials. c seems true.
d: The bonds in the products are polar, but the substances are non-polar.
Products: NH3, H2O, HF, HCl – all have polar bonds.
Are the substances non-polar? NH3 is polar, H2O is polar, HF is polar, HCl is polar. None are non-polar molecules.
So, this is false; the substances are polar.
e: The products, when dissolved in water, give acidic solutions.
NH3: Forms NH4OH, which is basic.
H2O: Neutral.
HF: Forms hydrofluoric acid, which is acidic.
HCl: Forms hydrochloric acid, which is acidic.
So, NH3 gives a basic solution, H2O neutral, HF and HCl acidic. Not all give acidic solutions. e is false.
Therefore, only c seems to be true for all products.
Is c absolutely true? For O2, the starting material is O2, which has very low solubility in water, and the product is H2O, which is the solvent, so yes. For others, as above.
So, I think c is the correct answer.
This question involves reacting hydrogen gas (H₂) with each of the gases in four containers: N₂, O₂, F₂, and Cl₂, under appropriate conditions. The reactions produce the following products:
Evaluating the options:
Thus, option c is correct for all products.

When H₂ reacts (under suitable conditions) with each diatomic gas we obtain:
N₂ + 3 H₂ → 2 NH₃ O₂ + 2 H₂ → 2 H₂O F₂ + H₂ → 2 HF Cl₂ + H₂ → 2 HCl
Products: NH₃, H₂O, HF, HCl.
• All four products are far more soluble in water than their corresponding reactant gases N₂, O₂, F₂, Cl₂ (which are only slightly soluble).
• Not all products are gases at room temperature (H₂O is liquid).
• HCl cannot form hydrogen bonds (only N, O, F form strong H‑bonds), so “every product forms H‑bonds” is false.
• Each product molecule is polar, so the substances are polar, not non‑polar.
• NH₃ gives a basic solution, so “all give acidic solutions” is false.
Thus statement (c) is the only universally true statement.

When H2 reacts with each gas under proper conditions, the following products are formed: • H2 + N2 → NH3 (ammonia), which dissolves well in water forming ammonium hydroxide. • H2 + O2 → H2O (water), which is completely miscible with water. • H2 + F2 → HF (hydrogen fluoride), a highly polar molecule that dissolves readily in water. • H2 + Cl2 → HCl (hydrogen chloride), which is very soluble in water to form hydrochloric acid. In contrast, the original diatomic gases (N2, O2, F2, Cl2) are very poorly soluble in water. Thus, the products obtained all have much better water solubility than the reactants.

When hydrogen reacts with each diatomic gas under appropriate conditions, the products formed are:
• N2 + H2 → NH3 (ammonia)
• O2 + H2 → H2O (water)

All these products are considerably more soluble in water than their corresponding reactant diatomic gases. For instance, although oxygen and nitrogen are only sparingly soluble in water, ammonia dissolves readily forming ammonium hydroxide, and both HF and HCl dissolve to give acidic solutions. Therefore, the correct answer is that the products dissolve in water better than the original substances.

Okay, let's tackle this chemistry question. The question is in Thai, so I need to make sure I understand it correctly. Let me read it again.
The question says: There are 4 containers each containing one type of gas: N2, O2, F2, Cl2. If hydrogen gas (H2) is reacted with each of these gases under suitable conditions until products are formed, which of the following statements is true regarding the products in all four containers?
The options are a to e. I need to figure out which one is correct.
First, I should recall the reactions between H2 and each of these gases. Let me list them out one by one.
H2 with N2: The reaction between hydrogen and nitrogen is a classic example. Under normal conditions, they don't react easily. But under high temperature and pressure with a catalyst (like iron), they form ammonia (NH3). The balanced equation is N2 + 3H2 → 2NH3.
H2 with O2: Hydrogen and oxygen can react explosively to form water. The reaction is 2H2 + O2 → 2H2O. This typically happens when ignited, like in the combustion of hydrogen.
H2 with F2: Fluorine is a very reactive gas. Even at room temperature, H2 and F2 react violently to form HF (hydrogen fluoride). The reaction is H2 + F2 → 2HF.
H2 with Cl2: Chlorine and hydrogen also react when exposed to light or a spark. The reaction is H2 + Cl2 → 2HCl. This forms hydrochloric acid gas.
Now, the question asks which statement is true for all four products. Let's look at each option:
Option a: Products are gases at room temperature.
Let's check each product:
H2O (from O2 and H2): Water is a liquid at room temperature. So that's a liquid, not a gas. So option a would be false because one of the products (H2O) is a liquid. So a is incorrect.
Option b: Products form hydrogen bonds.
Hydrogen bonds are bonds between hydrogen and highly electronegative atoms (N, O, F). Let's see each product:
NH3: Can form hydrogen bonds. The product itself can hydrogen bond with others, but the question is whether the product "has hydrogen bonds". The molecule itself has N-H bonds, which can hydrogen bond with other NH3 molecules. So yes, NH3 can form hydrogen bonds.
H2O: Definitely forms hydrogen bonds between molecules.
HF: Hydrogen fluoride can form hydrogen bonds because F is very electronegative. HF molecules can hydrogen bond with each other.
HCl: Hydrochloric acid. HCl is a polar molecule, but it doesn't form hydrogen bonds because Cl isn't electronegative enough (compared to O, N, F). HCl can't form hydrogen bonds; the H is bonded to Cl, which isn't as electronegative as O, N, or F. So HCl doesn't form hydrogen bonds. Therefore, the product HCl (from Cl2 and H2) doesn't form hydrogen bonds. So option b is not true for all four products. So b is incorrect.
Option c: Products dissolve in water better than the reactants.
Let's see each product and compare solubility with the original gases.
N2 (reactant) is a gas that's not very soluble in water. The product NH3 is highly soluble in water. So yes, NH3 is more soluble than N2.
O2 (reactant) is a gas that's slightly soluble in water. The product H2O is obviously very soluble (it's water itself). So yes, H2O is more soluble than O2.
F2 (reactant) is a gas; fluorine is not very soluble in water. The product HF is a gas that dissolves in water (hydrofluoric acid). HF is more soluble than F2. So yes.
Cl2 (reactant) is a gas that's somewhat soluble in water, but the product HCl is very soluble in water (as hydrochloric acid). HCl is more soluble than Cl2.
So all products are more soluble in water than their respective reactants. So option c seems correct. But let me check the wording again. The question says "ผลิตภัณฑ์ละลายน้ำได้ดีกว่าสารตั้งต้น" which translates to "the products dissolve in water better than the reactants". Since all four products are more soluble than their original gases, this would be true. So c could be correct. But let me check other options.
Option d: The bonds in the products are polar, but the substances are nonpolar.
Wait, let's analyze each product's polarity and the substance's polarity.
NH3: The N-H bonds are polar (N is more electronegative than H). The molecule itself is polar because of its trigonal pyramidal shape (due to lone pair on N). So the molecule is polar. So the statement says "polar bonds but nonpolar substance" – that's not true for NH3. So d is incorrect here.
H2O: The O-H bonds are polar, and the molecule is polar. So again, the substance is polar, so d is wrong.
HF: Polar bonds (F is very electronegative), and the molecule is polar. So again, the substance is polar. So d is wrong.
HCl: Polar bonds (Cl is more electronegative than H), and the molecule is polar. So again, the substance is polar. So all products have polar bonds and are polar substances. Therefore, option d is incorrect because it says the substances are nonpolar, which they are not. So d is wrong.
Option e: Products, when dissolved in water, give acidic solutions.
Let's see each product dissolved in water:
NH3 in water: NH3 is a weak base. It forms NH4OH, which is basic. So the solution would be basic, not acidic. So e is incorrect here.
H2O: Pure water is neutral. But if it's the product from H2 and O2, then H2O is neutral. So that doesn't give an acidic solution. So e is wrong here.
HF: Hydrofluoric acid is a weak acid. When dissolved in water, it partially dissociates into H+ and F-, making the solution acidic. So this would be acidic.
HCl: Hydrochloric acid is a strong acid, so it gives a strongly acidic solution.
So for the first two products (NH3 and H2O), the solutions are not acidic. Therefore, e is not true for all four products. So e is incorrect.
So the only option that is true for all four products is option c: the products dissolve in water better than the reactants. Let me confirm again each case:
N2 (gas) vs NH3 (liquid? Wait, NH3 is a gas at room temp, but when dissolved in water, it's more soluble than N2 gas. Wait, actually, the question is about solubility in water. N2 gas is not very soluble in water. NH3 gas is very soluble. So yes, NH3 is more soluble.
O2 gas is not very soluble, H2O is obviously more soluble (since it's water itself, but the question is about the product being more soluble than the reactant O2. Since H2O is a liquid, but when dissolved in water, it's the solvent. Wait, maybe I need to think differently. Wait, the reactant is O2 gas, and the product is H2O. Comparing the solubility of O2 in water versus H2O in water? Wait, that's not the right way. The question is comparing the product's solubility in water versus the original reactant gas's solubility in water. So O2's solubility in water is low, while H2O is the solvent, so it's infinitely soluble. So yes, H2O is more soluble than O2.
F2 gas is not very soluble in water, while HF is a gas that dissolves well in water (though HF is a gas at room temp? Wait, HF's boiling point is around -83°C, so at room temp it's a gas. But when dissolved in water, it forms hydrofluoric acid, which is a solution. So HF is more soluble than F2.
Cl2 gas has some solubility in water, but HCl gas is very soluble. So yes, HCl is more soluble than Cl2.
Therefore, option c is correct. The other options have exceptions. So the correct answer is c.
The question involves reacting hydrogen gas (H₂) with N₂, O₂, F₂, and Cl₂ under suitable conditions. The products formed are NH₃, H₂O, HF, and HCl, respectively. Analyzing each option:
Thus, the correct answer is c, as all products dissolve in water better than their reactants.

Alright! Let's tackle this chemistry problem. The user provided a question in Thai about chemical reactions involving hydrogen gas (H₂) with four different gases: N₂, O₂, F₂, and Cl₂. Each reaction occurs under suitable conditions, and we need to determine which statement is true regarding the products formed in all four containers.
First, I need to recall what happens when H₂ reacts with each of these gases:
N₂ + H₂: This forms ammonia (NH₃). The reaction is N₂ + 3H₂ → 2NH₃. Ammonia is a gas at room temperature and is highly soluble in water, forming a weak base.
O₂ + H₂: This produces water (H₂O). The reaction is 2H₂ + O₂ → 2H₂O. Water is a liquid at room temperature and doesn't form hydrogen bonds as a product but does have hydrogen bonding as a liquid.
F₂ + H₂: This reacts to form hydrogen fluoride (HF). The reaction is H₂ + F₂ → 2HF. HF is a liquid under standard conditions and is highly soluble in water. It's a weak acid but can form hydrogen bonds.
Cl₂ + H₂: This produces hydrogen chloride (HCl). The reaction is H₂ + Cl₂ → 2HCl. HCl is a gas at room temperature and is highly soluble in water, forming hydrochloric acid, a strong acid.
Now, let's analyze each option:
Option A: ผลิตภัณฑ์เป็นแก๊สที่อุณหภูมิห้อง (The products are gases at room temperature).
Option B: ผลิตภัณฑ์เกิดพันธะไฮโดรเจนได้ (The products can form hydrogen bonds).
Option C: ผลิตภัณฑ์ละลายน้ำ ได้ดีกว่าสารตั้งต้น (The products dissolve in water better than the reactants).
Option D: พันธะในผลิตภัณฑ์มีความเป็นขั้ว แต่เป็นสารไม่มีขั้ว (The bonds in the products are polar, but the substances are nonpolar).
Option E: ผลิตภัณฑ์ละลายนําแล้วให้สารละลายมีสมบัติเป็นกรด (The products dissolve in water to produce an acidic solution).
Between options B and C, both seem correct. However, the question asks for the statement that is true for all four products. While all products can form hydrogen bonds (B) and are more soluble in water than their gaseous reactants (C), the user might be looking for the most accurate and specific statement. Given that, option C is a strong candidate because solubility is a clear, measurable property that applies universally here.
