zapatos Posted December 18, 2012 Share Posted December 18, 2012 A simple, commonly cited, chemical equation for the combustion of black powder is 2 KNO3 + S + 3 C → K2S + N2 + 3 CO2.A balanced, but still simplified, equation is[93] 10 KNO3 + 3 S + 8 C → 2 K2CO3 + 3 K2SO4 + 6 CO2 + 5 N2.Although charcoal's chemical formula varies, it can be best summed up by its empirical formula: C7H4O[why?] An even more accurate equation of the decomposition of regular black powder with the use of sulfur can be described as: 4 KNO3 + C7H4O + 2 S —> 2 K2S + 4 CO2 + 3 CO + 2 H2O + 2 N2Black powder without the use of sulfur: 6 KNO3 + C7H4O —> 3 K2CO3 + CO2 + 6 CO + 2 H2O + 2 N2 http://en.wikipedia.org/wiki/Gunpowder Link to comment Share on other sites More sharing options...
MMK Posted December 22, 2012 Author Share Posted December 22, 2012 And what will be the change in enthalpy (dH) of the above reactions? Link to comment Share on other sites More sharing options...
