1.	Write the steps for balancing the chemical quation for the formation of ammonia by the combination of nitrogen and hydrogen.
Answer» Solution :`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 righthand 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)`
