chemistry

i have to write chemical formulas and balance them:
nitrogen and oxyen---> nitrogen monoxide
N2+02---->2NO

nitrogen monoxide and oxygen----> nitrogen dioxide gas.
NO2+O---->NO2 (i'm not sure about this, please check)

nitrogen dioxide and water----> nitrous and nitric acids

NO2 + H20---> NO3 + H2


please check and help

  1. The first reaction is correct as written.

    2NO + O2 -> 2NO2

    and

    2NO2 + H2O -> HNO2 + HNO3

    are the other two.
