If heat is written on the product side of an equation, what type of reaction is it?

Answer and explanation

Correct answer: Exothermic

In a chemical equation, substances and energy shown on the product side are formed or released during the reaction. If heat appears among the products, the reaction gives out heat to its surroundings and is therefore exothermic. Option B is correct. An endothermic reaction absorbs heat, while precipitation and electrolysis describe other reaction features, not the heat direction.
