Asked by Kim

a gaseous hydrocarbon reacts completely with oxygen gas to form carbon dioxide and water vapor. given the following data, determine (delta)HoF for hydrocarbon:
(delta)Horxn=-2044.5kj/mol hydrocarbon
(delta)HoF CO2= -393.5kj/mol
(delta)HoF H2O = -242kj/mol
denstity of CO2 and H2O product mixture at 1 atm, 200celcius= .751g/L
the density of hydrocarbon is less than the density of Kr at the same cond.





yeah but m,y teacher said that i am suppose to used the density to find the coefficient for the equation

cause hydrocarbon is HxCy= XCO2 + XH2O but i don't know the coefficient do you know how i can determine the coefficient using the density?
