The burning of a hydrocarbon will yield carbon dioxide and water.
C₂H₄ + 3 O₂ --> 2 CO₂ + 2 H₂O
From the balanced equation, 1 mol of C₂H₄ will produce 2 mol of CO₂. I'm not sure what to do besides looking up ΔH for the reaction.
What amount of carbon dioxide is produced per kJ of heat produced in burning ethene, C2H4?

Either look up the heat combustion of ethene or go to the delta Hformation stables and look up CO2, H2O, and ethene. Then dHrxn = (n*dHformation products) - (n*dHformation reactants)
