The chemical energy created is stored as or . is produced as well

Chemical energy is kept inside the bonds that are connected to withatoms with other atoms and molecules with other molecules.

Because chemical energy is kept in likestorage. It is an shape of potential energy.

When a  chemical reaction takes place, the stored chemical energy is let out.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
