Question

Write a balanced chemical equation for the decomposition of hydrogen peroxide (H2O2) into water and oxygen

Answer 1

Explanation:

Hydrogen peroxide (H2O2) when decomposes forms water and oxygen in a reaction as shown below

$H_2O_2 \rightarrow H_2O + O_2$

However, this reaction is not completely balanced as number of oxygen atoms on reactant and product sides are not same

So, the complete balance equation looks like

$2H_2O_2 \rightarrow 2H_2O + O_2$
