Leftover Aluminum Wire Lab Answer Key Instant

Your measured leftover was . That’s close! Small differences are due to handling, oxidation, or incomplete drying. Percent Yield of Copper (Another Common Question) Theoretical yield of Cu from 0.0372 mol CuCl₂ (1:1 mol ratio CuCl₂ to Cu): [ 0.0372 , \textmol Cu \times 63.55 , \textg/mol = 2.36 , \textg Cu ]

Don’t worry. You probably didn’t. That leftover wire is the entire point of the lab. leftover aluminum wire lab answer key

If you’ve just finished the classic single replacement reaction lab —usually with copper(II) chloride and aluminum wire—you’ve probably stared at your beaker and asked: Why is there still aluminum left? and Did I mess up my calculations? Your measured leftover was

[ 2Al + 3CuCl_2 \rightarrow 2AlCl_3 + 3Cu ] If you’ve just finished the classic single replacement

Here’s the breakdown of what you actually observed, the expected results, and how to check your work. You reacted aluminum (Al) with copper(II) chloride (CuCl₂):
