Correct option is D
Ans.(d) NO₂ and O₂
Explanation:
The correct answer is NO₂ (Nitrogen dioxide) and O₂ (Oxygen). When Lead Nitrate (Pb(NO₃)₂) is heated, it decomposes to form Lead(II) Oxide (PbO), Nitrogen dioxide (NO₂), and Oxygen (O₂). This reaction is an example of a thermal decomposition reaction.
2Pb(NO3)2→2PbO+4NO2+O22Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂2Pb(NO3)2→2PbO+4NO2+O2
Information Booster:
● NO₂ is a reddish-brown gas that contributes to air pollution.
● Lead(II) Oxide (PbO) appears as a yellow solid after decomposition.
● The evolution of NO₂ gas confirms the decomposition of Lead Nitrate.
● The reaction occurs at high temperatures (above 470°C).
