If energy is stored in chemical bonds, and bond formation is always an exothermic process, doesn't that imply that bond formation both stores and releases energy? How is this possible? I'm clearly not understanding some basic tenet of chemistry. For example, H+ and OH- neutralize to form H2O.
Reactions are also classified as exothermic or endothermic depending on the direction of the standard enthalpy change. Exothermic reactions occur when the enthalpy change is negative, which means energy is lost to the environment and the chemical bonds are formed in the reactions.
