Nitroglycerin is explosive, decomposing violently via the reaction: 4 C3H5N3O9 (s) ? 12 CO2 (g) + 6 N2 (g) + 10 H2O (g) + O2 (g) If 25.0g of nitroglycerin explodes in a 10.0 L rigid container, calculate the total pressure of all gasses present and their partial pressures, assuming the temperature is 500 OC.
