Calculating Bond Enthalpies

Postby elizabethrojas1G » Sun Feb 07, 2016 7:55 pm

When we balance an equation sometimes the O will have a fraction in front of it. So are we supposed to calculate the enthalpy with the fraction or are we supposed to balance the equation again until we have no fraction coefficients? I know sometimes it'll explicitly say "for one mole of...." but if it doesn't then do we use the one with fraction?

I believe you're supposed to calculate the enthalpy with the fraction coefficient. The overall equation is balanced, even if there might be a fraction coefficient.
