Copper (?) Iodide Lab Write-Up Due Tomorrow & Preparation

Remember, that tomorrow your lab first write-up for the year is due. Just as we discussed in class, you are not only doing the write-up for a grade in may class, but you are also auditioning for a college or university to receive lab credit if you end up passing the AP Chemistry test next spring. My big area of emphasis on the lab report will be the SEE's and the conclusion. Please make sure that your SEE's address situations that are plausible to your results. If you are overly generic, be prepared to receive no points for your SEE's portion of the report. If you are very specific in your plausible explanation, but contradict your findings, you will receive some credit. So it is better to be intricate and misguided than generic and not address anything of substance. The conclusion must address if the theory was met. Remember, you only have two choices for a plausible formula for copper (I or II) and iodide. Please also include a statement on how you would improve the lab. Just like any other report for any other class, you may want someone to read it for you and critique your work.

In the Chapters portion of my web page, I have posted two links for Vodcasts (new term, catchy, isn't it??) One is for empirical formula determination through combustion analysis and the other is how to determine a limiting and excess reactant. Before tomorrow, (Monday, 8/30), please watch the video on how to determine limiting and excess reactants as a refresher. I will cover the material quite quickly, so the Vodcast will allow you to review / learn at your own pace.

Finally, a AP Chemistry student emailed me with a helpful hint for WebAssign and entering scientific notation numbers. If for some reason (this is a random example) you needed to type Avogadro's number into WebAssign, instead of 6.02 x 10^23, you need to type it in just like it would appear as an answer on your graphing calculator: 6.02E23. If you had a small decimal number, you would type (example): 3.87E-7. Remember to keep plugging away at the WebAssign work. We will probably have a test later this week, so the work will probably need to be done by Friday. Also, your will be getting a review packet tomorrow (Monday, 8/30) in class and I will require the answers to be reported on WebAssign PRIOR TO THE CHAPTER 3 EXAM.
