Question

Can you explain the answer of this question below:100mL of gaseous hydrogen combines with 50mL of gaseous oxygen to give 100mL of water vapours. This can be explained on the basis of:A:Law of definite proportionsB:Gay Lussac&#8217;s lawC:Law of multiple proportionsD:Avogadro lawThe answer is b.

Answer

Acc. to Gay Lussac's Law of Gaseous Volume, under same pressure and temperature, whenever gases react, they do so in volumes and volumes of reacting gases bear a simple ratio with each other and with product gases formed.  100 : 50 : 100 : : 2 : 1: 2  Hence, option ( B) is correct.

Answer

Gay lussac law

Answer

According to law of definite proportions 2 H2+ O2 ----->2 H2O according to this 100ml of H2 and 50ml of O2 gives 100ml of H2O

Answer

B is correct option

Answer

Explanation:

The answer to the question is B: Gay Lussac's law. This can be explained on the basis of Gay Lussac's law of combining volumes of gases.

Gay Lussac's law states that 'the volumes of gases involved in a chemical reaction are in the ratio of small whole numbers, provided all gases are at the same temperature and pressure'.

Now, let's break down the given information and explain it in detail:

Given:
- 100mL of gaseous hydrogen combines with 50mL of gaseous oxygen to give 100mL of water vapors.

Explanation:
According to the law of combining volumes of gases, the ratio of the volumes of hydrogen and oxygen involved in the reaction should be in small whole numbers. In this case, the ratio of the volumes of hydrogen and oxygen is 2:1.

This means that for every 2 volumes of hydrogen gas, 1 volume of oxygen gas is consumed in the reaction. This is consistent with the given information, as 100mL of hydrogen combines with 50mL of oxygen.

When hydrogen and oxygen react, they combine in a 2:1 volume ratio to form water vapor. The reaction can be represented as follows:

2H₂(g) + O₂(g) → 2H₂O(g)

The balanced equation shows that 2 volumes of hydrogen gas react with 1 volume of oxygen gas to produce 2 volumes of water vapor. This is in accordance with Gay Lussac's law.

Therefore, based on the given information and the concept of Gay Lussac's law, we can conclude that the reaction can be explained by B: Gay Lussac's law.

Summary:
The given information about the combination of hydrogen and oxygen gases to form water vapor is consistent with Gay Lussac's law of combining volumes of gases. According to this law, the volumes of gases involved in a chemical reaction are in the ratio of small whole numbers. In this case, the ratio of the volumes of hydrogen and oxygen is 2:1, which is in accordance with the balanced equation of the reaction. Therefore, the answer to the question is B: Gay Lussac's law.

Answer

I think correct answer is B because Gay Lussac gives us the information about the volume
