What are the missing coefficients for the skeleton equation below? NH3 (g) + O2(g) → N2(g) + H2001)

4, 3 , 2 and 6

Explanation:

The reaction equation is given as;

       NH₃  +  O₂   →    N₂   +   H₂O

Now, we need to balance the reaction equation;

     NH₃  +  O₂   →    N₂   +   H₂O

put the numbers a,b,c and d;

    aNH₃  +  bO₂   →    cN₂   +   dH₂O  

We need to balance the equation algebraically, ;

  Conserving N;

      a = 2c

   Conserving H;

      3a  = 2d

   Conserving O;

      2b  = d

Now, let c = 1, a = 2, d  = 3 and b  =  

  multiply through by 2;

            a  = 4, b = 3, c  = 2 and d  = 6

Insert the parameters:

                  4NH₃  +  3O₂   →    2N₂   +   6H₂O
