      Well every living thing in the world is made of chemicals, and everything on and in the world is made of chemicals…so probably far too many to count! Remember that a chemical is any molecule, from water to sugar, table salt through to stuff like aspirin and other drugs. DNA is a chemical, the proteins in your hair are too!

      Yes. There are far too many chemicals to count because everything in the universe (not just our world!) is made up of chemicals.
