Balance the equation N2 +H20= NH3 + NO

N₂   +   3H₂O   →   2NH₃   +  3NO

Explanation:

The reaction expression is given as:

        N₂   +   H₂O   →   NH₃   +  NO

We are to balance this reaction expression.

To do this, assign a,b,c and d as the coefficients that will balance the expression:

              aN₂   +   bH₂O   →   cNH₃   +  dNO

Conserving N: 2a  = c

                    H: 2b  = 3c

                    O: b  = d

let a  = 1, c  = 2, b  = 3 and d = 3

So;

            N₂   +   3H₂O   →   2NH₃   +  3NO
