Question

which statement describes an endothermic reaction?
o energy is created in the reaction.
o energy is absorbed by the reaction.
o no energy is transferred by the reaction.
o energy is released by the reaction.

Explanation:

In an endothermic reaction, the system absorbs energy from the surroundings, usually in the form of heat. Energy cannot be created or destroyed according to the law of conservation of energy. If no energy is transferred, it's not a chemical - reaction involving energy change. Energy being released is characteristic of an exothermic reaction.

Answer:

Energy is absorbed by the reaction.
