Liquid benzene, C6H6, (density = 0.877 g/mL) can be used as a fuel. What is ?H in kJ for the combustion of 2.86 L of benzene producing CO2(g) and H2O? Assume that the heat of combustion of benzene is -4.18 x 103 kJ/mol. Enter your answer with three significant figures in exponential format (1.23 x 104 = 1.23E4).
given that the molar enthalpy of vaporization delta h for H2O(l) is 44kj at 298k, what is the standerd enthalpy change for the reaction 2H20(G)+ O2(g)---->2H2O(G)?
