Question

write one equation each for decomposition reaction where energy is supplied in the form of heat light or electricity​

Answer 1

Explanation:

Decomposition reaction requiring heat is known as thermal decomposition , CaCO3--------->CaO + CO2. Decomposition reaction requiring light is known as photo chemical decomposition reaction , 2AgCl-------2Ag + Cl2.

Answer 2

Answer:

Decomposition reaction requiring heat is known as thermal decomposition , CaCO3--------->CaO + CO2. Decomposition reaction requiring light is known as photo chemical decomposition reaction , 2AgCl-------2Ag + Cl2.

Explanation:

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