Understand that chemical reactions can either release energy or absorb energy during the process.
Recall that an exothermic reaction releases energy, usually in the form of heat, to the surroundings.
Recognize that an endothermic reaction absorbs energy from the surroundings, which means energy is taken in during the reaction.
Identify that neutralization and combustion reactions are specific types of reactions that typically release energy (exothermic).
Conclude that the type of reaction where energy is absorbed during the process is called an endothermic reaction.
