State whether the following statement is true or false:
On heating lead nitrate crystals, the emission of brown fumes occurs.
On heating lead nitrate crystals, the emission of brown fumes occurs.
(TRUE) The statement is $True$.
When lead nitrate $(Pb(NO_3)_2)$ is heated, it undergoes thermal decomposition to form lead oxide $(PbO)$, nitrogen dioxide $(NO_2)$, and oxygen $(O_2)$.
The chemical equation is: $2Pb(NO_3)_2(s) \xrightarrow{\Delta} 2PbO(s) + 4NO_2(g) + O_2(g)$.
The brown fumes observed are due to the evolution of nitrogen dioxide $(NO_2)$ gas.
