just a basic rookie question. What are the products when ethylene reacts with fluorine gas (i.e., burned in presence of fluorine)?(adsbygoogle = window.adsbygoogle || []).push({});

I was given the following data:

[itex]H_2 + F_2 \rightarrow 2HF \Delta H^{o} = -537 kJ [/itex]

[itex]C + 2F_2 \rightarrow CF_4 \Delta H^{o} = -680 kJ [/itex]

[itex]2C + 2H_2 \rightarrow C_2 H_4 \Delta H^{o} = +52.3 kJ [/itex]

I used the starting formula [itex] C_2 H_4 + 4F_2 [/itex]

I balanced out equations and got two possibilities, and I'm not sure which one to go with. In one, it forms 2 hydrogen molecules and 2 carbon tetrafluoride, and in the other it forms 1 C, 2 HF and 1 carbon tetrafluoride. BOTH of these balance out and I don't know which one to go with.
