Answer:

Hi mate

Explanation:

The decomposition of silver chloride into silver and chlorine is caused by the sunlight as per the analysis. The same way, silver bromide to gets decomposed. Hydrogen peroxide decomposition reaction: The decomposition of hydrogen peroxide into water and oxygen happens in the presence of light.

Helo mate here your ans

molecule breaks down to make simpler ones. There are three types of decomposition reactions:

Thermal decomposition reactions;

Elctrolytic decomposition reactions;

Photo decomposition reactions.

Thermal decomposition - such reactions are usually endothermic, since energy in the form of heat is required to break the bonds of the more complex molecule. Examples include
