    It appears you are posting part of a problem from a delta H calculation or something similar. Sometimes it is best to post the entire problem.
    All of these equations are done the same way. From the elements, the first two are
    N2(g) + 1/2O2(g) ==> NO2(g)
    B(s) + 3/2F2(g) ==> BF3(g)

    If you're going somewhere else with this question, fractions won't do for the balanced equation.
