Carbon, hydrogen, and oxygen are not the only elements that can be characterized by combustion analysis....

Carbon, hydrogen, and oxygen are not the only elements that can be characterized by combustion analysis. If a compound also contains sulfur or nitrogen, then it will form CO_2?2?? (from the carbon), H_2?2??O (from the hydrogen), N_2?2?? (from any nitrogen), and SO_2?2?? (from any sulfur). The amount of oxygen in the original sample is determined from subtracting the masses of the other elements from the total, as in the combustion analysis described earlier. If a 0.500 g sample of a...
