Answer 2

Heat, electricity,light are some of the sources of energy in decomposition reactions.

• The decomposition reaction is a type of chemical reaction where the reactant breaks into multiple products.

• Now,for the dissociation of the chemical reactant,a significant amount of energy input is necessary.

• This necessary energy source can be heat energy, electrical energy or light rays. The necessary energy sources may vary according to the reactants which are taking place in the decomposition reaction.
