Composition of Water by Volume Resulting from the Combustion of Hydrogen

Water is formed when hydrogen gas (H2) reacts with oxygen gas (O2) in a combustion reaction. The chemical equation for this reaction is:

2H2 + O2 -> 2H2O

Correct Composition

The correct composition of water by volume resulting from the combustion of hydrogen is:
- 66.7% hydrogen
- 33.3% oxygen

This means that in every molecule of water (H2O) formed from the combustion of hydrogen, approximately 66.7% of the volume comes from hydrogen and 33.3% comes from oxygen.

Explanation

In the chemical equation for the combustion of hydrogen to form water, 2 molecules of hydrogen react with 1 molecule of oxygen to produce 2 molecules of water. This ratio of hydrogen to oxygen in the reaction results in the volume composition of water being approximately 66.7% hydrogen and 33.3% oxygen.

Therefore, the correct composition of water by volume resulting from the combustion of hydrogen is 66.7% hydrogen and 33.3% oxygen.
