(HS.PS1B.a) Chemical processes, their rates, and whether or not energy is stored or released can be understood in terms of the collisions of molecules and the rearrangements of atoms into new molecules, with consequent changes in the sum of all bond energies in the...

(HS.PS1A.d) A stable molecule has less energy than the same set of atoms separated; one must provide at least this energy in order to take the molecule apart.
