Answer is:
A. Na₂S + FeBr₂ → 2NaBr + FeS.
B. MgSO₄ + CaCl₂ → MgCl₂ + CaSO₄.
E. AgNO₃ + NaCl → AgCl + NaNO₃.
Iron sulfide (FeS) has low solubility in water.
Calcium sulfate (CaSO₄) has low solubility in water and it will form white precipitate.
Silver chloride (AgCl) has low solubility in water and it will form white precipitate.
A. Na₂S + FeBr₂ → 2NaBr + FeS.
B. MgSO₄ + CaCl₂ → MgCl₂ + CaSO₄.
E. AgNO₃ + NaCl → AgCl + NaNO₃.
