Explanation / Answer

MOLECULAR: (NH4)2S(aq) + Pb(NO3)2(aq) ---> PbS(s) + 2NH4NO3(aq) IONIC: 2NH4+(aq) + S2–(aq) + Pb2+(aq) + 2NO3–(aq) ---> PbS(s) + 2NH4+(aq) + 2NO3–(aq) NET IONIC: S2–(aq) + Pb2+(aq) ---> PbS(s) --- Co(NO3)2(aq) + Na2SO4(aq) ---> NO REACTION --- MOLECULAR: AgNO3(aq) + NaI(aq) ---> AgI(s) + NaNO3(aq) IONIC: Ag+(aq) + NO3–(aq) + Na+(aq) + I–(aq) ---> AgI(s) + Na+(aq) + NO3–(aq) NET IONIC: Ag+(aq) + I–(aq) ---> AgI(s) --- MOLECULAR: )Al(NO3)3(aq) + 3KOH(aq) ---> Al(OH)3(s) + 3KNO3(aq) IONIC: Al3+(aq) + 3NO3–(aq) + 3K+(aq) + 3OH–(aq) ---> Al(OH)3(s) + 3K+(aq) + 3NO3–(aq) NET IONIC: Al3+(aq) + 3OH–(aq) ---> Al(OH)3(s) --- MOLECULAR: Zn(NO3)2(aq) + K2CO3(aq) ---> ZnCO3(s) + 2KNO3(aq) IONIC: Zn2+(aq) + 2NO3–(aq) + 2K+(aq) + CO32–(aq) ---> ZnCO3(s) + 2K+(aq) + 2NO3–(aq) NET IONIC: Zn2+(aq) + CO32–(aq) ---> ZnCO3(s) --- KCl(aq) + NaNO3(aq) --->NO REACTION
