hi mate follow me ✌✌

Explanation:

Answer:-

Decomposition reactions are those reactions in which a compound is broken into two or more new compounds.

Combination reactions are those reactions in which two substances are combine.d to form a new substance.

CaO + CO2 —> CaCO3 + energy

In above examples, both the reactions are same but show opposite directions, so decomposition reaction is called the opposite of combination reaction.
