An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
This is how I remember it...Ex: ExitsExothermic: Releases energyYour answer would be: C, a reaction that releases energy into the environment.If you ever need help on endothermic....En: Absorbs or enterEndothermic: Absorbs energyHOPE THIS HELPS! ^_^
