Question

Do chemical reactions absorb,release, or absorb & release energy? or neither?

Answer 1

Some release and some absorb.

Answer 2

both

exothermic reactions give off energy because the products have less energy than the reactants (are more stable)

endothermic reactions need energy input because the products have more energy than the reactants (are less stable).
