Examples include the decomposition of mercuric oxide into mercury and oxygen and calcium carbonate into calcium oxide and carbon dioxide, along with reactions involving metal hydroxides and unstable acids.

The formula tells which elements and how many of each element are present in a compound. Formulas are written using the elemental symbol of each atom and a subscript to denote the number of elements. This notation can be accredited to Swedish chemist Jons Jakob Berzeliu. The most common elements present in organic compounds are carbon, hydrogen, oxygen, and nitrogen.
