The bomb that destroyed the Murrah Federal Office building in Oklahoma City in April 1995 was constructed from ordinary materials: fertilizer(ammonium nitrate) and fuel oil ( a mixture of long-chain hydrocarbons, similira to decane, C10H22). Determine the standard enthalpy change of the following explosive reaction by using the apprpriate enthalpies of formation (delta Hf, for C10H22 = -249.7 kJ/mol) 3 NH4 NO3(s) + C10H22 (l) + 14O2 (g) 3 N2(g) 17 H2O (g) + 10 CO2 (g) Answer in kJ ?
