Write a chemical equation for photodecomposition reaction.

Photodecomposition is the decomposition or splitting of a compound into its components in the presence of light. For example,

sunlight

• AgCl (s) -----------------------> Ag (s) + Cl (g)

sunlight

• H${}_2$O${}_2$ (l) ------------------------> H${}_2$O (l) + O${}_2$ (g)
