✔ 最佳答案
C₇H₅N₃O₆(s) → (3/2)N₂(g) + (5/2)H₂(g) + 3O₂(g) + 7C(s)For each mole of trinitrotoluene (C₇H₅N₃O₆) decomposed :
No. of moles of gases formed = [(3/2) + (5/2) + 3] = 7 mol
Work = Δ(PV) = Δ(nRT) = RT Δn = [8.314 J/(mol K)] × (307.95 K) × (7 mol) = 17920 J = 17.92 kJ

All carbohydrates, including all monosaccharides (C₆H₁₂O₆), disaccharides (C₁₂H₂₂O₁₁) and polysaccharides (C₆(H₂O)₅n), have the mole ratio H : O = 2 : 1.
Also, my other compounds (such as methanal (HCHO), acetic acid (CH₃COOH), propanedial (CH₂(CHO)₂), etc.) have the mole ratio H : O = 2 : 1.
