उत्तर
The neutral gas evolved when lead nitrate undergoes thermal decomposition is oxygen.
Explanation:
When lead nitrate undergoes thermal decomposition, the neutral gas evolves as oxygen. In the decomposition process, both oxygen and nitrogen dioxide gas is evolved. However, NO2 is an acidic oxide and forms nitric acid with water. So, the correct answer is oxygen.
