Answer:
reactants: 2 O2
products: 3 CO2, 4 NO2, 6 H2O
Explanation:
In a combustion, a combustible material, which generally is composed of C, H, O, N, and S, is combusted, that is, react with oxygen after a spark was produced; obtaining fire, heat and subproducts, including ashes and gases.
Oxygen is always one of the reactants of a combustion.
If Nitrogen was present in the combustible, NO2 (or other nitrogen oxides) will be produced.
If Carbon was present in the combustible, CO2 will be produced (also CO can be produced).
If Hydrogen was present in the combustible, H2O will be produced.
