Answer:The metal nitrate (A) is lead nitrate (Pb(NO3)2) on heating it produces lead oxide, Nitrogen dioxide (B) and oxygen gas (C)
(1) 2Pb(NO3)2→2PbO+4NO2+O2
on reaction with potassium iodide mixture of lead iodide and potassium nitrate forms
(2) Pb(NO3)2+2KI→PbO2+2kNO3
Alloy made of using lead is used in Soldering purpose.
Therefore A=[Pb(NO3)2),B=NO2
C=O2 D=PbI+KNO3
(2) Decompostion type Reaction
(2) Double displacement type Reaction.
