Question

What is true of a decomposition reaction? The reactants are usually a metal and a nonmetal. The reactants are generally two ionic compounds in an aqueous solution. The addition of energy in the form of heat or electricity is often required. Water is usually one of the reactants.

Answer 1

Answer

In a true decomposition reaction, the addition of energy in the form of heat or electricity is often required.

Explanation

A decomposition reaction is a chemical reaction that starts with single reactants to give new compounds as the products. These reaction requires a source of energy that could be light, heat  or electricity to facilitate the breaking-down of the chemical bonds.

Answer 2

Answer:

The addition of energy in the form of heat or electricity is often required.
