A sample of an unknown gas with a molar mass of 11.73 is placed in a vessel with a volume of 3,342 mL at a temperature of 18.4 °C. If the pressure is 4.3 atm, how many grams of this gas are present? Your Answer: Answer units
= Given the enthalpies of reaction: S(s) + O2(g) → SO2(g) AH = -297kJ 2S(s) + 302(8) ► 2S03(8) AH = -791kJ Calculate the enthalpy change (AH) for the reaction: 2802(g) + O2(g) → 2503(8) a) -494 kJ Ob) b) 494 kJ OC c) -197 kJ d) 1088 kJ
5.5 L of O2 reacts with excess Hz to form H2O according to the balanced equation below: 2H2(g) + O2(g) → 2H2O(g) If the pressure is 9.9 atm and the temperature is 239.2 K, how many grams of H20 are formed? Your Answer: I Answer Answer units
