Answer 2

Answer:

combination reaction, two or more reactants combine and form a single substance

AB → A + B

Explanation:

During the decomposition reaction, a single substance decomposes and forms two or many substances. Whereas in combination reaction, two or more reactants combine and form a single substance. Hence, decomposition reaction is called the opposite of combination reaction.

A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation: AB → A + B. In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction.
