Rewrite and balance the equation below
N2+H2-> NH3

N2 + 3H2 —> 2NH3

Explanation:

N2 + H2 —> NH3

The equation can be balance as follows:

There are 2 atoms of N on the left side and 1atom on the right side. It can be balance by putting 2 in front of NH3 as shown below:

N2 + H2 —> 2NH3

Now there are 6 atoms of H on the right side and 2 atoms on the left side. It can be balance by putting 3 in front of H2 as shown below:

N2 + 3H2 —> 2NH3

Now, the equation is balanced.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
