B

`Pb(NO_(3))_(2)`

C

`Cu(NO_(3))_(2)`

D

`AgNO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`KNO_(3)` on heating gives `O_(2)` while all others give `NO_(2)`
`{:(" "2KNO_(3)overset(Delta)rarr 2KNO_(2) + O_(2)),(2 Pb(NO_(3))_(2)overset(Delta)rarr 2PbO + 4 NO_(2)+O_(2)),(2Cu(NO_(3))_(2) rarr 2 CuO + 4 NO_(2) + O_(2)),(" "2AgNO_(3) overset(Delta)rarr 2Ag + 2NO_(2) + O_(2)):}`
