Black (smoky) gunpowder is a mixture of sodium nitrate, sulfur, charcoal. Write the equations of the reaction that occur during the combustion of gunpowder?

Saltpeters are minerals that contain nitrates of alkali, alkaline earth metals and ammonium, in other words, they are salts of nitric acid. Thus, sodium nitrate has a molecular formula in the form of NaNO3, sulfur – S, and charcoal – C (but it should be understood that charcoal contains not only carbon).

Thus, the reaction equations for the combustion of black powder in molecular form are as follows:

NaNO3 + С + S = Na2S + CO2 + N2, where the mixture NaNO3 + С + S is black (smoky) powder.
