Answer 2

Word equation of $2H_{2}O \rightarrow 2H_{2}(g)+O_{2}(g)$ is: 2 moles of water decompose to give 2 moles of hydrogen gas and 1 mole of oxygen gas.

Explanation:

• The electrolysis of water molecules cause it to decompose to hydrogen gas and oxygen gas.
• It is a type of decomposition reaction.
• In it 2 moles of water molecule is capable of giving 2 moles of $H_{2}(g)$ and 1 mole of $O_{2}(g)$.
• Therefore, the word equation can be written as: 2 moles of water decompose to give 2 moles of hydrogen gas and 1 mole of oxygen gas.
