Question

write two observations when Lead Nitrate is heated in a test tube name the type of reaction write a balanced equation to represent above reaction and how will you create an artificial aquatic system which is self sustainable​

Answer 1

Explanation:

When lead nitrate is heated , lead oxide along with nitrogen dioxide and water is obtained .

observations:

(i) white precipitate is formed

(ii) brown fumes are evolved

Equation : Pb(NO3)2  ----∆------> PbO + NO2 + H2O
