They must have more than one product. A combustion reaction occurs when a reactant combines with oxygen, many times from the atmosphere, to produce oxides of all other elements as products; any nitrogen in the reactant is converted to elemental nitrogen, N 2.Many reactants, called fuels, contain mostly carbon and hydrogen atoms, reacting with oxygen to produce CO 2 and H 2 O. 4H + O2 2H2O C7H16 + 11O2 7CO2 + 8H2O Cl2 + 2NaBr Br2 + 2NaCl 2Na + 2H2O 2NaOH + H2 2.
