Wouldn’t it be terrifying if our clothes, food, and houses spontaneously combusted? Molecular bonds store tremendous amounts of energy, but generally are very stable. In order to release the energy, you have to add more first - like applying a match to a firework. These videos will overview standard enthalpy, entropy, and how to find out if a reaction is spontaneous.
