Answer:
The correct answer is The energy of the products is less than the energy of the reactants, so energy is released into the surrounding environment.
Step-by-step explanation:
In exothermic reactions, there is a release of energy in the environment which comes out converted into heat. These types of reactions are the product of a process of transformation of molecules called chemical reaction.
The energy that an exothermic reaction uses to carry out is less than the amount of energy it releases, so as the answer says: This energy is released because the energy of the products is less than the energy of the reactants.
An exothermic change can be for example the processes of condensation and solidification.
