Question

what happens when lead nitrate is heated

Answer 1

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.

Answer 2

When lead nitrate is heated it decomposes to form :

a. Lead oxide
b. Nitrogen dioxide
c. Oxygen

In equation we can write it as :

2Pb(NO3)2 --heat--> 2PbO + 4NO2 + O2

This type of chemical reactions are called thermal decomposition reaction.
