Write the reaction equation: Br2- KBr- KCl- AgCl

1.2K + Br2 = 2KBr (reaction of bromine and potassium to form potassium bromide, proceeds at room conditions).

2. AuCl + KBr = AuBr + KCl (reaction of a dilute solution of potassium bromide and gold (I) chloride to form potassium chloride and gold (I) bromide).

3. AgNO3 + KCl = AgCl + KNO3 (reaction of a diluted solution of potassium chloride and silver (I) nitrate to form potassium nitrate and silver (I) chloride).
