In the following sequence of reactions, identify the compounds (A), (B

1.	In the following sequence of reactions, identify the compounds (A), (B), (C) and (D) Na_(2)CO_(3)overset(SO_(2))rarr(A)overset(Na_(2)CO_(3))rarr(B)underset("Heat")overset("S")rarr(C)overset(AgBO_(3))rarr(D)
Answer» `Na_(2)SO_(3), NaHSO_(3), Na_(2)S, Ag_(2)S` `NaHSO_(3), Na_(2)SO_(3), Na_(2)S_(2)O_(3), Ag_(2)S` `NaHSO_(3),Na_(2)SO_(4) ,Na_(2)S,Ag_(2)O` `Na_(2)SO_(3),Na_(2)SO_(4) ,Na_(2)S_(2)O_(3),Ag` Solution :`Na_(2)CO_(3)+2SO_(2)+H_(2)Orarr2NaHSO_(3)+CO_(2)` `2Na_(2)SOO_(3)+Soverset(triangle)rarr2Na_(2)S_(2)O_(3)OVERSET(AgNO_(3))RARrAg_(2)+H_(2)SO_(4)`
