$H_2O$ and $O_2$

Vedclass · Answer

(A) Hydrogen peroxide $(H_2O_2)$ is an unstable compound.When exposed to light,it undergoes decomposition to form water $(H_2O)$ and oxygen gas $(O_2)$.The balanced chemical equation for this decomposition is: $2 H_2O_2(aq) \rightarrow 2 H_2O(l) + O_2(g)$.Therefore,it is stored in dark-colored bottles away from light to prevent this decomposition.

Hydrogen peroxide is stored away from light because it can get decomposed when exposed to light as:
