Question

which statement correctly compares endothermic and exothermic reactions? endothermic reaction exothermic reaction endothermic absorbs heat; exothermic releases heat endothermic releases heat; exothermic absorbs heat both release energy as light both absorb energy from surroundings

Explanation:

Endothermic reactions absorb heat (as shown by the "Energy absorbed" arrow in the endothermic reaction diagram). Exothermic reactions release heat (as shown by the "Energy released" arrow in the exothermic reaction diagram). The other options are incorrect: endothermic doesn't release heat, exothermic doesn't absorb heat, and they don't both release energy as light or both absorb energy from surroundings.

Answer:

Endothermic absorbs heat; exothermic releases heat
