Chemistry is the science of substances, specifically the combination of elements to make other elements. Mass-energy is never created or destroyed, and everything can be explained in terms of physics, no one knows this better than a chemist. In the days before modern science, chemistry was called alchemy and it was the study of the classical elements earth, wind, water, and fire. Today we know the four forces are electromagnetic, gravitational, strong, force, and weak force. We understand these forces create the atoms, that create the elements, that create the molecules, that create the world around us. With great power comes great responsibility.
