solve this for me..urgent!!!?

based on thermo-chemical solve this for me:

1/2N(small 2 behind N) + 1/2O(small 2 behing O) - NO (delta)rh=90,5

NO + 1/2 O(small 2) - NO2 (delta)rh=5,66

solve reduction heat oxidation nitrogen in nitrogen (IV) oxide using the 'something'...

1) 2N(small 2) + O(small 2) (then 2 arrows pointing both sides, one above the other.) NO(small 2)

yeah, I know, details are poor... :( :) :) :(

    :o Oh, the fustrating limitations of the keyboard!

    You notations are (still) confusing.

    Is there somewhere else you can link to to give the proper notations? 2N (2) = 4 atoms of Nitrogen Right?

    2 sets of Nitrogen molicules.
