Detailed Solution

The above statement is true.
A reaction where energy is released in the form of light or heat is often called an exothermic reaction. In other words, in a chemical reaction, energy or heat is transferred to the environment or heat is evolved is termed an exothermic reaction. So, the temperature of the environment increases. Combustion reactions, oxidation reactions and neutralisation reactions are all exothermic reactions.
In exothermic reactions, during the bond-making process, they release energy rather than being supplied. So, as a result of the bond-making, heat energy is released. In final words, in these reactions, the quantity of energy needed to interrupt the required bonds within the reactants is a smaller amount than the quantity of heat energy released when the bonds within the products are made. Also, it’s the opposite of an endothermic reaction. The chemical equation of exothermic reactions is: Reactants → products + energy
