Write the steps for balancing the chemical quation for the formation of ammonia by the combination of nitrogen and hydrogen.

Explanation

`Na+H_(2)rarrNH_(3)` (Unbalanced equation)
(i) Examine the number of atoms of different elements present in the unbalanced equation.
(ii) In the above reaction, N and H of both the sides are unbalanced.
(iii) To balance hydrogen, `H_(2)` is multipled by 3. It makes 6H-atoms on the left hand side.
(iv) Now to balance hydrogen atoms on the right hand side, `NH_(3)` should be multiplied by 2. It makes 6H-atoms on this side
(v) Now to balance nitrogen atoms, they are counted separately for both the side and we will find that, nitrogen atoms are 2 on both the sides.
(vi) Balanced chemical equation will be :
`N_(2)+3H_(2) rarr2NH_(3)`
