Barium chloride in excess is added to be sure that the reaction is complete.

When exposed to air, calcium chloride can absorb moisture and become hydrated, forming a white, powdery substance. It is hygroscopic, meaning it has a strong affinity for water molecules in the air. This property allows calcium chloride to be used as a desiccant to remove excess moisture from the air.
no change
you get sodium chloride NaCl
When aqueous ammonia is added in excess to a solution of silver chloride, the white precipitate of silver chloride dissolves to form a colorless, tetrahedral complex ion called [Ag(NH3)2]+. This complex ion is soluble in excess ammonia due to the formation of a stable coordination complex.
Ammonium chloride is thermally decomposed in ammonia and hydrogen chloride.
To calculate the percent chloride using the Volhard method, you measure the excess silver nitrate used to titrate the chloride ions in the sample. You then use the volume of excess silver nitrate and the molarity of the silver nitrate solution to calculate the moles of chloride present. Finally, calculate the percent chloride by dividing the moles of chloride by the sample weight and multiplying by 100.
When excess iron(III) chloride is added to zinc, it can undergo a displacement reaction where the zinc displaces the iron from the iron(III) chloride solution. The products of this reaction would be zinc chloride and iron.
Silver chloride is not soluble in water.
Sodium chloride is easily dissolved.
