When fuels burn they react with oxygen in the air. Air is a mixture of gases made up of mainly nitrogen and oxygen gas.

Composition of Air

Products of Combustion

When a hydrocarbon burns in a plentiful supply of oxygen, carbon dioxide and water are produced.

Combustion

This is known as complete combustion.

This can be shown by the following experiment...
