Question : From the given options, choose the one which is not a product of the decomposition reaction of Lead nitrate.
Option 1: Nitrogen dioxide
Option 2: Oxygen
Option 3: Nitrogen
Option 4: Lead oxide
Correct Answer: Nitrogen
Solution : The correct option is Nitrogen.
Lead nitrate (Pb(NO3)2) undergoes decomposition upon heating, and one of the products is lead (II) oxide (PbO). Nitrogen is not a product of the decomposition reaction of lead nitrate. The decomposition reaction of lead nitrate is as follows:
Pb(NO3)2 → PbO + NO2 + 12O2
Nitrogen dioxide, oxygen, and lead oxide are produced through decomposition.
