$2 {H}_{2} {O}_{2} \to 2 {H}_{2} O + {O}_{2}$

#### Explanation:

This reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

$2 {H}_{2} {O}_{2} \to 2 {H}_{2} O + {O}_{2}$
