Question

When hydrogen is burned, it reacts with oxygen and produces?

Answer 1

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

Answer 2

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:

$2H_2(g)+O_2(g)\rightarrow 2H_2O(l)$

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.
