which reaction is exothermic? a reaction that absorbs energy from the environment a reaction that requires an activation energy a reaction that releases energy into the environment a reaction that does not involve a change in energy
Answer
Brief Explanations:
Exothermic reactions release energy to the surroundings in the form of heat or light. Reactions that absorb energy are endothermic. Requiring activation energy is a characteristic of many reactions but not specific to exothermic ones. Reactions with no energy - change do not exist in reality.
Answer:
a reaction that releases energy into the environment
