Question

Decomposition is reverse of __________ (redox/combination) reaction.

Answer 1

In a decomposition reaction, one reactant breaks into two or more products. This is the reverse of a combination reaction.

But a combination reaction is a type of chemical reaction in which two or more reactants combine to form a single product.

From the above statements, it is clear that decomposition is the reverse combination reaction. So, the correct answer is the combination.
