Review from module 4:
Is this reaction exothermic or endothermic?
Exothermic, because the products are lower energy than the reactants
Endothermic, because the products are lower energy than the reactants
Exothermic, because the products are higher energy than the reactants
Endothermic, because the products are higher energy than the reactants
