Question

On heating, lead nitrate forms oxides of nitrogen and lead. The oxides formed are__________ .

• A. $N_2O$, $PbO$
• B. $NO_2$, $PbO$
• C. $NO$, $PbO$
• D. $NO$, $PbO_2$

Answer 1

Answer: (B)

$NO_2$, $PbO$

Answer 2

Lead nitrate on heating it decomposes to lead monoxide $( PbP )$, nitrogen dioxide $\left( NO _{2}\right)$ and oxygen $\left( O _{2}\right)$. $2 Pb \left( NO _{3}\right)_{2} \rightarrow 2 PbO +4 NO _{2}+ O _{2}$ Hence option $B$ is correct.
