Correct Answer: Nitrogen dioxide


Solution : The correct option is Nitrogen dioxide .

When Lead Nitrate (Pb(NO 3 ) 2 ) is heated, it undergoes thermal decomposition. The reaction can be represented as: Pb(NO 3 ​) 2 (s)​ → PbO(s)​ + NO 2 (g) ​+ O 2 (g)​

When Lead Nitrate (Pb(NO 3 ) 2 ) is heated, it decomposes to form Nitrogen dioxide (NO 2 ), oxygen (O 2 ) and Lead oxide (PbO). So, the gas produced in this reaction is Nitrogen dioxide (NO 2 ).
