a white coloured heavy metal compound A on heating gives a solid yello

1.	a white coloured heavy metal compound A on heating gives a solid yellow substance B, reddish brown gas C and another color gas D . Identify A B C D and write the chemical reaction of all
Answer» The metal NITRATE (A) is lead nitrate (Pb(NO 3 ) 2 ) on heating it produces lead oxide, Nitrogen DIOXIDE (B) and OXYGEN gas (C) (1) 2Pb(NO 3 ) 2 →2PbO+4NO 2 +O 2 on reaction with POTASSIUM iodide mixture of lead iodide and potassium nitrate forms (2) Pb(NO 3 ) 2 +2KI→PbO 2 +2kNO 3 Alloy made of using lead is used in SOLDERING purpose. Therefore A=[Pb(NO 3 ) 2 ),B=NO 2 C=O 2 D=PbI+KNO 3
