When lead nitrate (Pb(NO3)2) is heated, it undergoes a decomposition reaction to form the products. Let`s analyze each option of the given answer:

Option 1: PbO2 and N02

This option is incorrect. Lead nitrate does not produce PbO2 (lead dioxide) and N02 (nitrogen dioxide) upon heating.

Option 2: PbO and N02

This option is correct. The heating of lead nitrate results in the formation of PbO (lead(II) oxide) and N02 (nitrogen dioxide) as the products.

Option 3: PbO and NO

This option is incorrect. The reaction of lead nitrate does not produce NO (nitric oxide) along with PbO.

Option 4: PbO2 and NO

This option is incorrect. Lead nitrate does not produce PbO2 and NO upon heating.

In summary, when lead nitrate is heated, it decomposes to form PbO (lead(II) oxide) and N02 (nitrogen dioxide).
