Hydrogen reacts with oxygen to produce water:
2H2 + O2 --> 2H2O

Answer: It produces water molecule.

Explanation:

When hydrogen gas reacts with oxygen gas, it leads to the formation of water molecule.

The chemical equation for the formation of water molecule follows:

[tex]2H_2(g)+O_2(g)\rightarrow 2H_2O(l)[/tex]

By Stoichiometry of the reaction:

2 moles of hydrogen gas reacts with 1 mole of oxygen gas to produce 2 moles of water molecule.

Hence, it produces water molecule.
