Introduction to Stoichiometry

Question 1

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?

Revolt · Accepted Answer

81%

Question 2

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

Revolt · Accepted Answer

excess reactant aqueous copper chloride; excess reactant aluminum; product solid copper; product aqueous aluminum chloride; water

Question 3

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

Revolt · Accepted Answer

Outcome: The limiting reactant will be fully consumed.; Reason: The limiting reactant is the one that completely reacts.

Question 4

How did your question compare to the lesson question above?

Revolt · Accepted Answer

almost the same idea and wording; similar, but different wording; related, but a little out of focus; different, but I understand why the question makes sense
