Solution

Balanced chemical equation:
A chemical equation in which the numbers of atoms of each element on both th sides of the equation is equal is called balanced equation.
Step 1 : Representation of the chemical reaction
2Pb(NO₃)₂ →2PbO + 4NO₂ + O₂
_{Step 2 : Calculating the number of atoms on both side of reaction}
Elements Number of atoms on reactant side Number of atoms on product side
Pb 2 2
O 12 12
N 4 4
_{Step 3: Balancing the uneven numbers of atoms on both the side of reaction}
as the number of lead , oxygen and nitrogen atoms is equal on the both side of reaction.
given equation is already balanced.
Hence, the equation is balanced.
2Pb(NO₃)₂ (s) → 2PbO(s) + 4NO₂ (g) + O₂(g)
