Introduction to Stoichiometry Answers

You already saw that 1.00 g of Al should yield 3.53 g of copper for the reaction below.3CuCl2(aq) + 2Al(s)⟶ 2AlCl3(aq) + 3Cu(s)However, impurities and errors can occur easily. Suppose that only 2.86 g of copper is produced. What is the percent yield of the reaction?

When you perform this reaction, what substances could remain at the end of the reaction? Check all that apply.

Which elements did you include in your hypothesis? Check all that apply.
