This is the combustion reaction for octane, #C_8H_18#., a volatile and very flammable alkane that is a component of gasoline.

The balanced chemical reaction is

#2C_8H_18 + 25O_2 -> 16CO_2 + 18H_2O#

Here's a nice diagram of this reaction I've found on a French forum

The chemical reaction described is

#C_8H_18 + 12.5O_2 -> 8CO_2 + 9H_2O#
