Chem 35.5

Below is a list of students that received credit for completing the survey assignment.

Survey

Three students did not receive credit: 074176, 073820 and 052095.

Below is summary of the survey results:

Survey Results

So far….so good…. 34 students have filled out the survey. I believe that six more students need to complete the survey form or they face getting zero points for this simple assignment (some of you need these points so please remind your batchmates).

I am told that my final grades are due to the Department by April 2. After 9PM tomorrow (the time the survey will be closed) I will post the point tallies and show a conversion to letter grade so that you can see how your final grade will be determined (I am not suppose to “give out” official grades but with you doing the math I think I preclude breaking house rules.

I hope final exams went well guys. Have a joyful, safe and restful weekend.

Howdy Folks,

For the last quiz grade please fill out the teaching evaluation form found at the website below. As of 11:23PM this evening your total point tally includes 15 extra points for completing this assignment. The 15 ponts will stay if this survey is completed and submitted online by 9PM Saturday March 29th. If it is not completed, the 15 points will be changed to a 0 (absolutely no exceptions).

The survey website can be found here:
http://www.wcer.wisc.edu/salgains/student/default.asp?BadID=1

You will need to enter three items to gain entrance. They are:

1) Course ID: 714718447
2) Password: you know this already from the last class
3) Your student ID number
Note no names, only student ID’s. This means if you complete the survey and use your name for the ID, you will not receive credit.
4) Complete the 25 survey questions. The survey is 100% anonymous as the ID’s are not seen until closing time. Please be honest as this will help me improve my classes in the future.

Oh yea, the results of the final exam can be found here:
Final Exam Results

The number of correct responses divided by 50 forms the % score. The percentage times 250 points is the number of points you earned for the Final Exam.

Hi Folk. Everyone seems to be excited to fill out the evaluation. The details will be posted after Monday’s Final Exam.

RBG

Comprehensive Final Exam:
March 24 7:30AM – 9:30 C114 (50-multiple choice)

You will not need a blue book just a good pencil(s) and a calculator.

I made a quick list of things you should know already to be studying.

1. conversion problems with ppt, ppm, ppb, pptr
2. mean and standard deviation calculation
3. Confidence limits and Q-test
4. accuracy and precision
5. % mass or % volume to molarity
6. equilibrium concepts, what, why, interpretation
7. Q vs Kc or Kp equilibrium problem and ICE table
8. dilution and molarity related problems
9. acid base theory and concepts from Bronsted and Lewis
10. Ka ICE problem problem
11. buffers concepts
12. preparing a buffer with Henderson Hasslebach equation
13. pH, pOH, Kw and pKw and application to problems
14. Ka, pKa and Kb and pKb
15. titrations of strong-strong, weak strong and what their equivalence point
16. weak acid and weak base equilibrium problems
17. solubility vs molar solubility and Ksp problem application
18. gravimetric analysis problems
19. soda ash titration problems
20. EDTA titration problems
21. activity and ionic strength conceptual understanding
22. EM Radiation, E = hv, wavelength and speed of light
23. Beer-Lambert Law and spectrophotometry
24. coordination complexes, ligands
25. nomenclature of complex ions
26. identifitying types of isomerism
27. oxidation numbers and finding oxidants and reductants
28. balancing redox equations
29. using reduction tables to find spontaneous reactions, Ecell
30. galvanic cell understanding of components
31. short hand notation of cells

The last quiz grade will be to complete the teacher evaluation. This information was posted in class and will be completed here on this blog.

Good luck on the Exam folks. Mail me if you need to ask a question.

RBG

A few students asked for a few examples of EDTA calculations so I placed a few answers from problems in Chapter 15 in Skoogs text. All of this is very straight forward stoichiometry and calculations you did for your lab as well. Relevant are: 15: 1,2,14,16, 38. Good luck.

RBG

Folks, I probably do not need to say this, but I will anyway. Please bring a blue-book and a calculator to the Exam as you have for each and every Exam that you have had in my classes.

Someone asked whether the Nernst Equation would be on the Exam. The answer is no–we did not cover in class (next topic). Again the Exam starts at 7AM, so please let your classmates know especially those that enjoy sleeping in.

RBG

Hi Folks,

The Exam will start at 7:00AM for those who want additional time. I have asked Kevin to contact your classmates. Please help him spread the word. Thanks!

Ok, the Exam is set na. There will be four major questions each with 7-10 mini-questions. The exam is all short answer with no multiple choice–it just seem to make sense on this one.

The themes are Absorption Spectrophotometry, Transition Metal Complexes, EDTA titrations, and Electrochemistry–all stuff we covered in great detail in class. The Exam problems are similar to the assigned problems and homework. If you know the concepts and the homework you should find it easy.

Lecture slides and homework solutions have been updated.

See you Monday at 7:00AM sharp.

Hi Guys,

Just to summarize the Presentation for next Tuesday morning:

–Time Limit: 10-15 minute long.
–My recommendation goes something like this (which does not necessarily have to be followed). A big goal is to be yourself, be creative and use your imagination to inspire and be interesting.
–No cue cards, no note reading or you can’t read from the slides. You guys will have to practice. 1-person can give the presentation from the group although all of you will responsible for knowing the material when questions are asked.

A reasonable slide approach (but not cast in stone) would be:

Slide 1 Presentation Title, Group Member Names
Slide 2 Tell Us What You Did and Why (tell an interesting story)
Slide 3 Tell Us How You Did It (collecting the sample, the technique, what it is, what it measures, who did it)
Slide 4 Tell Us What You Found (results, boo-boos, does it make sense)
Slide 5 Tell Us why we should care (significance)
Slide 6 Tell Us Anything Else You think we should know about your Group and why you deserve a good or poor grade.

+/- 2 slides is ok show me that you care about what you are doing.

Please go to the website shown below and read the material shown there:

http://www.writing.eng.vt.edu/slides.html

I like the presentation approach presented there so much that all of my future classes that use Powerpoint will use this model. It just seems to make a lot of sense. Download the Assertion-Evidence Slides powerpoint templates (most of them are the same so pick one) and use this as the format for your Powerpoint presentation. I also have the book that the website references. It’s a good read and very informative. If you want to deviate from the template that’s ok, but if you best improve on the website concept. Ian-Ken, your classmates and I will assess your knowledge and understanding of the technique so everyone in the Group please be prepared. Don’t hesitate to ask questions.

The Silberberg problems for Chapter 21 include: 2,9,10,11,13,17,22,29,31,38,40,44,46,50,53,58,62,64,65,70,72,73,82,85,87

Exam 3 = March 17 (Monday)
Comprehensive Final Exam = March 24 7:30AM C114

Later,

RBG

Here is the list of homework problems for Chapter 15 in Skoog and Chapter 23 Silberberg (which previously were shown in class). The EDTA problems all involve straight forward molarity, dilution and titration. Skip the fractional equilibrium material in the Chapter.

Skoog Chapter 15: #1,13,14,16,38
Silberberg Chapter 23: 45,46,47,48,53,55,58, 67,73

Lecture slides have been updated as well.
