Answer :
1. Potential of a chemical substances to undergo transformation in a chemical reaction is known as chemical energy. The chemical energy is stored in the bonds of chemical compounds.
Hence, in a compound, chemical energy is contained in bonds.
2. The process in which one or more substance known as reactants are converted to one or more completely new substances known as products are formed is known as a chemical reaction.
Hence, during a chemical reaction bonds of the reactants are broken, and bonds of the products are formed.
