Thermochemical Equations

We learned that chemical potential energy is stored in the bonds between atoms. Reactants and products have differing amounts of stored energy, so reactions either release or absorb energy.  We call these reactions endothermic or exothermic reactions, depending on the direction of energy flow.Consult the text on p.298-299 and 302-303 for help.
