which reaction is exothermic?\no a reaction that absorbs energy from the environment\no a reaction that requires an activation energy\no a reaction that releases energy into the environment\no a reaction that does not involve a change in energy

which reaction is exothermic?\no a reaction that absorbs energy from the environment\no a reaction that requires an activation energy\no a reaction that releases energy into the environment\no a reaction that does not involve a change in energy

Answer

Brief Explanations:

Exothermic reactions release energy to the surroundings. Reactions that absorb energy are endothermic. All reactions require activation energy and a reaction with no energy - change does not exist.

Answer:

a reaction that releases energy into the environment
