It doesn't have. While it is made a smaller ingredients it would be impossible to break these all down to form a chemical composition.
The approximate percentages for the main 5 constituents are: * Nitrogen 75.00% * Oxygen 23.00% * Argon 1.00% * Water 0.30% * Carbon dioxide 0.05%
Chemical formula is representative for the chemical compositon of a compound. Chemical equation is representative (describe) for a chemical reaction.
