Answer:
The coefficients of the balanced equation will change depending on the fuel. The fuel can be almost anything including methane (CH4), propane (C3H8), butane (C4H10), octane (C8H18) or sugar (C6H12O6).
The balanced equation for methane is CH4 + 2 O2 -> CO2 + 2 H2O

The balanced equation for octane is
2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O
The combustion of methane or octane is exothermic; it releases energy.
CH4 + 2 O2 -> CO2 + 2 H2O + energy
The energies of the products are lower than the energiies of the reactants. The excess energy is released as heat and
