The Problem 1. Use the balanced combustion reaction above to calculate the enthalpy of combustion (Hcomb) for C8H10. 2. Use combustion enthalpy to calculate the number of kilograms of C8H10 burned to generate the same amount of energy as the nuclear reactors. 3. Calculate the number of Liters of CO2 produced (at 1520. mmHg and 250.C) if the amount of C8H10 found in 2. is burned?
