White coloured metal nitrate a on heating gives a yellow residue b alo

1.	White coloured metal nitrate a on heating gives a yellow residue b along with evolution of a brown gas g and a colourless gas c
Answer» 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 (2) DECOMPOSTION TYPE Reaction (2) Double displacement type Reaction. Explanation: mark me as brainliest

White coloured metal nitrate a on heating gives a yellow residue b along with evolution of a brown gas g and a colourless gas c

Answer»

Answer:

The metal nitrate (A) is lead nitrate (Pb(NO

)

) on heating it produces lead OXIDE, Nitrogen dioxide (B) and oxygen gas (C)

(1) 2Pb(NO

)

→2PbO+4NO

on reaction with potassium iodide MIXTURE of lead iodide and potassium nitrate forms

(2) Pb(NO

)

+2KI→PbO

+2kNO

Alloy made of using lead is used in SOLDERING purpose.

Therefore A=[Pb(NO

)

),B=NO

C=O

D=PbI+KNO

(2) Double displacement type Reaction.
