A chemist wants to extract copper metal from copper chloride solution. The chemist places 0.25 grams of aluminum foil in a solution of 0.40
grams of copper (II) chloride. A single replacement reaction takes place. What are the likely observations when the
reaction stops?
Unbalanced equation: CuCl2 + Al - AlCl3 + Cu
A .About 0.90 grams of copper (II) is formed, and some aluminum is left in the reaction mixture
B. About 0.20 grams of copper (II) is formed, and some aluminum is left in the reaction mixture
C. About 0.90 grams of copper (II) is formed, and some copper chloride is left in the reaction mixture
D, About 0.20 grams of copper (II) is formed, and some copper chloride is left in the reaction mixture
