Reddish brown gas is liberated from the white solid indicating that its nitrogen dioxide.
The yellow solid residue is lead oxide. So the white solid is lead nitrate
- White solid is lead nitrate - Pb(NO3)2
- The gas liberated is reddish brown which is nitrogen dioxide and the other gas is oxygen
- The balanced equation for this reaction is - 2Pb(NO3)2 → 2 PbO + 4 NO2 + O23.
- This was thermal decomposition reaction as heat was involved in it.
