im doing ethene so it is -84.0. Howe do i spilt the two up? the second question confuses me and im completely frazled about what to do. C2H6(g) + 3O2(g) = 2CO2(g) + 2H2O(g) =(2mol CO2 x -393.5kJ/1 mol CO2 + 2mol H2O x -241.8kJ/ 1 mol H2O) - (1mol C2H6 x -84.0/ 1 mol C2H6 + 3mo...

how do i express the enthalpy of reaction calculated in question above as a molar enthalpy of reaction per mole of carbon dioxide?
chemistry
ok i got to (2mol CO2 x -393.5kJ/i mol CO2 + 2mol H2O x -241.8kJ/ 1 mol H2O) - (1mol C2H6 x -94.0/ 1 mol C2H6 + 3mol O2 x 0kJ/ 1 mol O2) = (-1270.6kJ0 - (-84.0) = -1186.6kJ is this right? and how do i do the second part about expressing the enthalpy of reaction calculated in q...
