Final answer:
The type of energy changes that accompany the mixing of a strong acid to a strong base is chemical energy.
Step-by-step explanation:
The type of energy changes that accompany the mixing of a strong acid to a strong base is chemical energy.
When a strong acid and a strong base are mixed, a chemical reaction occurs. This reaction involves the breaking and forming of chemical bonds, which releases or absorbs energy in the form of heat. Since the reaction involves a change in the arrangement of atoms in the acid and base, it is an example of a chemical change, and the associated energy change is called chemical energy.
For example, when hydrochloric acid (HCl) is mixed with sodium hydroxide (NaOH), the reaction produces water (H2O) and sodium chloride (NaCl). The breaking and formation of bonds between the hydrogen, chlorine, sodium, and hydroxide atoms involves the release of energy as heat, which is an example of chemical energy.
