Answer to Question #115564 in General Chemistry for Bob

Question

A 5 g piece of aluminum foil is placed in a solution containing 3 g of Copper (II) Chloride. What would be the resulting colour of the solution in this scenario? Use stoichiometry calculations to solve this question.

Answer 1

2Al+ 3CuCl2 = 2AlCl3 + 3Cu

5/54=0,0925925926

3/405 = 0,00740740741.

0,00740740741x54= 0.4 g react Al.

1,42222222 g of Cu producing.
