What means of "chemical store of energy"

And another question what "PH" means I need the answers now plz​

Answer 1

Answer:

Chemical stores of energy are associated with the configuration of the atoms and molecules that make up a substance. During chemical reactions energy is transferred when atoms and molecules are separated or combined.

pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
