1. Take about 0.5 g of lead nitrate powder in a boiling test tube.
2. Hold the boiling tube with a test tube holder.
3. Heat the boiling tube over a flame.
4. We observe that on heating of lead nitrate brown fumes of nitrogen dioxide are released.
5. On heating lead nitrate, it decomposes and gives lead oxide, oxygen and nitrogen dioxide.
6) Reaction : 
7) This is also an example for thermal decomposition reaction.
