need help with 2. Use the following enthalpies of formation to calculate an approximate enthalpy of reaction, AHrxn for: (5 pts) C3H8 (g) + 502 (g) → 3CO2 (g) + 4 H20 (1) C(s) + O2 (g) - CO2 (g); AH = - 393.5 kJ/mol H2(g) + 42 02 (g) - H20 (1); AH = - 285.5 kJ/mol 3 C(s) + 4 H2(g) → C3H8 (g); AH r = - 103.8 kJ/mol
A gas-filled weather balloon with a volume of 52.0 L is held at ground level, where the atmospheric pressure is 768 mmHg and the temperature is 20.0 °C. The balloon is released and rises to an altitude where the pressure is 0.0635 bar and the temperature is -8.83 °C. Calculate the weather balloon's volume at the higher altitude. V= L
