If heat is written on the products side of a chemical equation, what is the nature of the reaction?

Answer and explanation

Correct answer: Exothermic

Writing heat on the products side means that heat is produced and released to the surroundings during the reaction. Such a reaction is called exothermic. In an endothermic reaction, heat is absorbed, so it is conventionally shown on the reactants side. The labels displacement and decomposition describe possible substance changes, not the heat direction, so they cannot be concluded from this information. Option A is correct.
