Dear student

1. Sodium carbonate(A) + Ba(NO3)2  give s a white precipitate of Sodium nitrate(B) which reacts with HCl to give sodium chloride
Na2CO3 + Ba(NO3)2  -->  BaCO3 + 2NaNO3 
NaNO3 + HCl  --> NaCl + HNO3

2.Ag2S( silver sulphide ) + Pb(CH3COO)2 --->  PbS(black precipitate) + Ag(CH3COO)2

Please post remaining queries in separate threads.

Regards
