Answer 1

Answer:

Given that lead nitrate, having chemical formula Pb(NO3)2 is heated in a test tube. The two observations of this chemical reaction are: (i) When lead nitrate is heated, it decomposes into lead oxide (PbO), nitrogen dioxide (NO2), and oxygen gas (O2). The type of this reaction is thermal decomposition reaction.
