Calcium sulfide has the chemical formula CaS. The chemical formula of calcium sulfide is CaS; the ions are Ca2+ and S2-. To identify a chemical property, we look for a chemical change. A chemical change always produces one or more types of matter that differ from the matter present before the change. The formation of rust is a chemical change because rust is a different kind of matter than the iron, oxygen, and water present before the rust formed.
