Which coefficients balance the following equation __ N2+___H2--->___NH3

To balance this equation first write down the nine by or atoms on both sides of the equation

Left side Right side

N = 2. N = 1

H = 2. H = 3

Next balance the N atoms first by placing 2 on the right side. Now.

Left side Right side

N = 2 N = 2

H = 2. H = 6

Finally place the coefficient of 3, on the left side for hydrogen and you have a balanced equation:

Left side Right side

N = 2 N = 2

H = 6. H = 6.

N2 + 3H2 = > 2NH3.
