Ag_(2)S+NaCNrarrAoverset(Zn)rarrB , Hence A and B are -

Cl_(2) on reaction with excess of NH_(3) gives

Cl_(2) on reaction with excess of NH_(3) gives

SO_(2)Cl_(2) is dissolved in water to obtain H_(2)SO_(4) and HCL. In two different cases, excess Ba(OH)_(2) and excess CH_(3)COOAg were added to obtain precipitates having masses m_(1) and m_(2) grams respectively , starting with one mole of SO_(2)Cl_(2) in each case. Then ( Ba=137, Ag=108, S=32, Cl=35.5) :-
