Why is the chemical energy of a battery potential energy and not kinetic energy

Potential energy is stored energy that has not been used yet. kinetic energy is energy that is being used instead of being stored. batteries have stored energy that is not being used until the battery is put into a device that can convert the energy that is stored into energy that is used. in example, putting batteries into a remote puts the stored energy into use by powering the remote.

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
