Answer: In a combination reaction two or more substances are combined to form new substance while in the decomposition reaction one substance decomposes into two or more substances. Hence, the decomposition reactions are called opposite of combination reactions.

Decomposition reaction CaCO3 (s) ⇨ CaO (s) + CO2 (g)

Combination reaction H2 (g) + Cl2 ⇨ 2HCl (g)
