Question

Chemical reactions that release energy possess reactants with lower energy than their products. True or False

Heat is the most common form of energy absorbed or released in chemical reactions. True or False

Answer 1

1. False, that reaction would be endothermic and endothermic reactions have reactants with higher energy than the products.

2. I believe it would be true. I know heat energy is very common but I can't say 100% certain that it's the most common.
