The heat of combustion of naphthalene (C10H8) is - 5157 kJ/mol. Using these data and data in Appendix C, calculate the heat of hydrogenation of naphthalene.
12.0 moles of gas are in a 3.00L tank at 22.7C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a=2.300L^2*atm/mol^2 and b=0.0430 L/mol.
