Homework Help: chemistry

Posted by ben on Monday, October 11, 2010 at 2:02pm.

Use bond energies to predict the molar enthalpy of combustion of acetylene gas.
2C2H2 + 5O2--> 4CO2 + 2H2O

I am confused as to how to do the 2C2H2 in relation to the bonds?

how many c-c bonds would there be, or would they be triple bonds?
