Question

Name the brown fumes liberated when lead nitrate is heated. Write the balanced chemical equation for this reaction

Answer 1

2Pb(NO3)2 _____. 2PbO + 4NO2+O2

It is Thermal decomposition reaction .

The brown fumes were of Nitrogen dioxide.

Answer 2

Answer:

The brown fumes liberated when lead nitrate is heated is of Nitrogen dioxide. This is the thermal decomposition reaction. The balanced chemical equation for this reaction is following:

1Pb (NO3)2  2PbO + 4NO2 + O2

Thus, this will be the reaction when lead nitrate is heated and will release Nitrogen dioxide. You can further have a group discussion on the same.
