Question

Lead nitrate on thermal decomposition produces

• A. Lead oxide
• B. Nitrogen dioxide
• C. Both (a) and (b)
• D. Carbon dioxide

Answer 1

The correct option is C Both (a) and (b)

Lead nitrate on heating undergo thermal decomposition reaction to form a yellow residue of lead oxide and produces brown fumes of nitrogen dioxide.
$\underset{Leadnitrate}{2Pb(N{O}_3{)}_{2\left(s\right)}}\to \underset{Leadoxide}{2Pb{O}_{\left(s\right)}}+\underset{Nitrogendioxide}{4N{O}_{2\left(g\right)}}+\underset{Oxygen}{O_{2\left(g\right)}}$
