   Na2S(aq) + Hg(NO3)2(aq) → 2NaNO3(aq) + HgS(s)

   Hg^2+(aq) + S^2-(aq) → HgS(s)

   Mercury(II) sulfide is precipitated.

2. kodie says

   sodium sulfide = Na2S

   mercury (II) nitrate = Hg(NO3)2

   Na2S(aq) + Hg(NO3)2(aq) –> HgS(s) + 2NaNO3(aq)

   To find the precipitates, look at the solubility rules (link below)

   precipitate = HgS (coz all nitrates are soluble)

   hope this helps;-D
