Text Solution

Verified by Experts

The correct Answer is:
C
`AgNO_(3)overset(Delta)(rarr)underset((w))(Ag)+underset((x))(NO_(2))+O_(2)`
`underset((x))(NO_(2))+H_(2)OrarrHNO_(2)+HNO_(3)`
`Ag+HNO_(3)rarrunderset((y))(AgNO_(3))+NO+H_(2)O`
`underset((y))(AgNO_(3))+underset(("Excess"))(Na_(2)S_(2)O_(3))rarrunderset((x))(Na_(3)[Ag(S_(2)O_(3))_(2)])+NaNO_(3)`
