The bomb that destroyed tje Murrah Federal Office Building in Oklahoma City in April 1995 was constructed from ordinary materials: fertilizer (ammonium nitrate) and fiel oil (a mixture of long-chain hydrocarbons, similar to decane, C10H22). Calculate the total enthalpy (delta H, in kJ) when 11.40 grams of ammonium nitrate (NH4NO3, 80.04 g/mol) reacts according to the following reaction. 3NH4 NO3(s) + C10H22 (l) + 14O2 (g) → 3N2(g) 17 H2O (g) + 10CO2 (g)
