State burns in bomb calorimeter in excess oxygen

Reference no: EM13163861

1.829 g of an unknown hydrocarbon (126.6 g/mol) burns in bomb calorimeter in excess oxygen. The heat capacity of the calorimeter,Cv, = 5.832 kJ/ºC and ?T =5.154 ºC. Find ?E for this hydrocarbon in kJ/mol. Using the technique of the previous problem ?E was found to be -2,000.00 kJ/mol of an unknown liquid hydrocarbon at 298 K. In another experiment it was determined that for each mole of hydrocarbon, 7 moles of oxygen gas are consumed and 5 moles of CO2 gas and 3 moles of H2O liquid are produced. Find ?H per mole of this hydrocarbon (in kJ) at 298 K
