Reactants

2C8H18 + 25 O2

Or Octane + Oxygen

octane is the biggest part of gasoline.

Product

The number of atoms don't change.

16 CO2 + 18 H2O or 8 Carbon dioxide + 9 water.

Octane and oxygen mix in car engine and spark plugs Ignition them.

The octane and oxygen igniting and change into water and carbon dioxide and coming out of the exhaust pipes.
