Solution

When lead nitrate is heated .thermal decomposition reaction takes place as follows
$2 P b (N O_{3})_{2} + h e a t \to 2 P b O + 4 N O_{2} + O_{2}$
Here $P b (N O_{3})_{2}$ is lead nitrate.
$P b O$ is a lead oxide, nitrogen dioxide $N O_{2}$ which appears as brown fumes and oxygen are produced.
