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.
In order to condense water vapor to water, the molecules must lose energy. Chemistry at About.com states that most exothermic reactions, unlike phase changes, result in higher entropy in the products. An example of an exothermic reaction that is not a phase change is combustion. After wood burns, the result is much less ordered than the reactants that went into the reaction, according to Scientific American.
