give the example of decomposition reaction under sunlight
Answers
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.

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

Electrolytic decomposition - such reactions occur when an electric current is passed through an aqueous solution of a compound. Two classic examples are the electrolysis of water
