To solve these problems, swap the anions and cations:

If there is at least one insoluble product, it will precipitate out as a solid and the reaction will occur.

If all the products are soluble, then no reaction occurs.

1) KCl (aq) + CaS (aq) --> NO REACTION (K2S and CaCl2 are soluble)

2) CrBr2 (aq) + Na2CO3 (aq) --> CrCO3 (s) + 2 NaBr (aq)

3) 3 NaOH (aq) + FeCl3 (aq) --> Fe(OH)3 (s) + 3 NaCl (aq)

4) 2 NaCl (aq) + Hg2(C2H3O2)2 (aq) --> Hg2Cl2 (s) + 2 Na(C2H3O2) (aq)

5) (NH4)2SO4 (aq) + SrCl2 (aq) --> SrSO4 (s) + 2 NH4Cl (aq)

6) NH4Cl (aq) + AgNO3 (aq) --> AgCl (s) + NH4NO3 (aq)
