Choose the correct code by identifying (X), (Y) and (Z) in each case f

1.	Choose the correct code by identifying (X), (Y) and (Z) in each case for the changes indicated: (i) CrO_(2)Cl_(2) overset(KOH) to (X) overset(conc." "H_(2)SO_(4))to(Y) overset(AgNO_(3))to(Z) (ii) CrCl_(3)(aq) underset(NaOH)overset("excess")to (X) underset(H_(2)O," boil")overset(Na_(2)O_(2))to (Y) underset("acetate")overset("lead")to (Z) (iii) ZnSO_(4)(aq) overset(Na_(2)CO_(3))to (X) overset(Delta)to (Y) underset("nitrate, "Delta)overset("cobalt")to(Z) (iv) CuCl_(2)(aq) underset(H_(2)S)overset(NH_(4)OH)to (X) underset(Delta)overset(HNO_(3))to (Y) underset("excess")overset(KCN)to(Z)
Answer» `X=K_(2)CrO_(4)""Y=K_(2)Cr_(2)O_(7)""Z=Ag_(2)CrO_(4)` `X=[Cr(OH)_(4)]^(-) ""Y=Na_(2)CrO_(4)""Z=PbCrO_(4)` `X=ZnCO_(3)""Y=ZnO""Z=CoZnO_(2)` `X=CuS""Y=Cu(NO_(3))_(2)""Z=K_(3)[Cu(CN)_(4)]` Answer :D
