Expert Answer:

Dear Diksha,

The unbalanced chemical reaction can be written as follows:

Zn + AgNO3 → Zn(NO3)2 + Ag

There are 6 oxygen atoms on the product side and 3 oxygen atoms on reactant side. Hence, multiply AgNO3 by 2. It balances nitrogen atoms also on both the sides, that is 2 nitrogen atoms.

The reaction can be written as follows:

Zn + 2 Ag NO3 → Zn(NO3)2 + Ag

But, now silver atoms are unbalanced. By multiplying silver atoms by 2, the number of silver atoms on both the sides get balanced. Now all the atoms on reactant and product sides are balanced. The balanced reaction is as follows:

Zn(s)  + 2AgNO3(aq) → Zn(NO3)2(aq)  + 2Ag(s)
