Answer
(a) 2 AgNO$_{3}$(aq) + Na$_{2}$S(aq) → Ag$_{2}$S(s) + 2 NaNO$_{3}$ (aq)
2 Ag+(aq) + S$^{2-}$(aq) → Ag$_{2}$S(s)
(b) H$_{2}$SO$_{4}$ (aq) + Pb(NO$_{3}$)$_{2}$ (aq) → PbSO$_{4}$ (s) +
2 HNO$_{3}$ (aq)
SO$^{2-}{4}$(aq) + Pb$_{2}$+(aq) → PbSO$_{4}$ (s)
(c) Hg(NO$_{3}$)$_{2}$ (aq) + 2 NaI(aq) → HgI$_{2}$ (s) + 2 NaNO$_{3}$ (aq)
Hg$_{2}$+(aq) + 2 I–(aq) → HgI$_{2}$ (s)
(d) CdCl_{2} (aq) + 2 AgClO_{4} (aq) → 2 AgCl(s) + Cd(ClO_{4})_{2} (aq)
Cl–(aq) + Ag+(aq) → AgCl(s)
