Answer:
Lead nitrate on heating decomposes to lead monoxide, nitrogen dioxide and oxygen. NO2 is liberated, along with oxygen, as a reddish brown gas. The residue left is lead monoxide. ... If however you keep heating dry Pb(NO3)2 crystals, around 470°C it does not melt but decompose.

When the lead nitrate is heated up then the lead nitrate decomposes the heat, and the nitrogen oxide appears to be the brown fumes, and then the oxygen is produced, but when the leas nitrate is heated up then it decomposes to lead nitrogen oxide, lead mono oxide and the oxygen.
