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?

im so confused with this also

what the heck.

oh my goshh

you guys havent gotten it..?

wait what?

well mrs. k just gave me a huge clue!

I'm going to dig a Love Canal in your lawn... tomorrow night. 8:36. Silhouette. Lamp post. You know the drill.
