Answer:

Yes.

Explanation:

A decomposition reaction is a reaction where a reactant is broken down into simpler bonds. Decomposition reactions are usually endothermic, because they need energy to overcome the bond strength between the reactant. The newly formed bonds are responsible for new products, which are usually compounds.

Usually, the energy supplied to activate the decomposition reaction comes in the form of heat (fire).
