A chemical formula is the way a particular chemical (element or compound) is represented using the letters given in the Periodic Table. For example, the chemical formula of oxygen is O2 and the chemical formula of caron dioxide is CO2

A word equation describes a chemical reactionusing the names of chemicals only. For instance, the word equation for respiration is:

glucose + oxygen => carbon dioxide + water

A formula equation also describes a chemical reaction, but uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:

CH4 + 2O2 => CO2 + 2H2O
