Hydrogenation reactions, in which H2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. In the simplest case, ethene (C2H4) and H2 form ethane (C2H6). If 129 kJ is given off per mole of C2H4 reacting, how much heat (in kJ) is released when 13.3 kg of C2H6 forms? Enter a positive number since released implies a negative number. Enter to 2 decimal places.
