Chemical

Brand name starter

Chemical describes anything relating to chemistry—the science of substances and their interactions.

As an adjective, it modifies processes, reactions, or properties: chemical bonds, chemical warfare, a chemical burn.

As a noun, a chemical is any substance with a distinct molecular composition, though in everyday speech it often implies something artificial or synthetic: The label says no chemicals added.
