Answer:
When the energy is absorbed in a chemical reaction, we can say that this is an endothermic reaction.
Explanation:
An endothermic reaction is a chemical reaction that absorbs energy instead of releasing energy, like exothermic reactions.
To be considered an endothermic reaction, the chemical reaction must have a low energy reagent and for that reason, they need to absorb energy so that there is a rearrangement of the reactant molecules, forming products with high energy.
