When hydrogen peroxide decomposes naturally, what are the products?

The products are water and oxygen gas (${O}_{2}$).
Hydrogen peroxide, ${H}_{2} {O}_{2}$ (very slowly) decomposes naturally into water and oxygen gas.
$2 {H}_{2} {O}_{2} \left(l\right) \to 2 {H}_{2} O \left(l\right) + {O}_{2} \left(g\right)$
