On heating lead nitrate forms oxides of nitrogen and lead. The oxides formed are:
1. N2O, PbO 
2. NO2, PbO 
3. NO, PbO 
4. NO, PbO2

 
 



Hint: One of the products is nitrogen dioxide

On heating lead nitrate it produces brown-colored nitrogen dioxide NO2 and lead (II) oxide.

  \(Pb(NO_2)_2 \xrightarrow {\Delta} 4 NO_2 + PbO+O_2\)
