Explanation:

Answer 2

Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated.

CaCO 3⟶Heat CaO+CO 2

Photo decomposition is a chemical reaction in which a substance is broken down into simple substances by exposure to light (photons).

2H 2 O 2⟶sunlight 2H 2 O+O 2

Electrolytic decomposition may result when the electric current is passed through an aqueous solution of a compound.

2H 2 O(l) ⟶electricity 2H 2 (g)+O 2 (g)
