Final Exam stats ... Part I was better than Part II.
Several students misunderstood the use of "en"...
Several students confused tetrahedral field versus octahedral field...
But overall... many will be pleased with their outcome/performance. ;-)
AVG for Pt I word problems = 64%
AVG for Pt II = 50%
Overall AVG = 64% (129/200)
(includes bonus problem, up to 25 points for the ACS
exam and up to 10 pts ACS bonus)
High = 203
Low = several less than 100
5/18 11 PM
Phew... it's finally over ... for you. =)
It was good to see everyone smiling after the exam. Please contact Jane to coordinate another date for the BBQ, as this coming Monday will not work out for me and my family to host.
I have completed Part I and starting on Part II. You should relax, rest and recharge for other finals. Goodluck on them.
5/15
ACS portion has been graded. If you want to know your score on this exam, please send me an email.
(It will be worth a portion of your final - approximately "one" word problem )
Class AVG = 40 (good work!)
National AVG = 33
5/14
Dr Su will have office hours/study group on Friday from 11 to 1 PM. Meet at my office and we will find a room.
Final Exam II: Meet Monday at 1:25 PM downstairs at Sci 108.
Meet at 3:40 PM, back upstairs at our lab (S242) to celebrate and pick up stuff. "I will provide the super saturated CO2 solutions!"
PS#10 solutions are now online and on the bulletin board.
Blue - Final Review worksheet. Some questions are not as relevant as others and some we did not cover at all ( although you may have had a little in 101A ). You should be able to tell which ones.
5/7
Borax Lab - I am returning the reports - full credit for those who turned
it in, since I was not able to grade them in a timely matter. ;-)
To CHECK your calculations - delta H should be around + 100 KJ/mole. delta
S is ~ + 330 J/K mole.
Forgot to mention this in lecture: Quiz #3 is OUT OF 24 points. I found a typo in the very last question. I mixed up my x and o's. Sorry. All quizzes total up to 90, so some of you earned a few bonus points. =)
5/5
Some chemistry or "metallic" humor...(a former student sent it to me) ;-)
5/4
Oops! Typo(s) in my final study NOTE. I have corrected it. Same info, but the dates should be correct now.
4/30
Extra credit - self assessment. Write a paragraph about your own experiences this semester, as you are reviewing for the finals. You may address it to future 101B students if that helps- giving them advice on what you discovered about your own "learning."
Email this to me by Monday 5/18/09 and I will give up to 5 points towards your overall score in the course.
Have a great weekend. Remember, Quiz on Crystal Structures on Tuesday -most likely at the end of lecture.
4/27 9:45 PM
Lecture will be at 8 AM - back to "normal" for the rest of the term. The Quiz will be after I finish lecturing, unless you convince me to give it first. ;-)
4/25
Monday Lab will start at about 9 AM - Vanadium experiment.
Preparing for Part I of your Final Exam.
As part of your final, you will take the American Chemical Society's first year general chemistry exam. It is a standardized test. Those that had me for 101A will find it of similar format to the one you took at the end of the semester (if I gave it). You do not need to study specifically for it (ACS examm), because you already have been - I do not look at the exam, so that I do not "teach to the test." You will all do fine - that is the typical result ( of past classes ). You should and can prepare for the word problems.... See the note - those who had me for 101A and 40 will find the tips familiar.
4/21
Good to finally see everyone again! I have updated due dates for items - so check My Progress.
Quiz #2 on MO Theory, will be next Tuesday (4/28)
Quiz #3 on Crystal Structures of Metals and Salt will be in 2 weeks.
Back to a "normal" schedule for lecture - Thursday at 8AM. ;-)
4/14
Sounds like a good break was had by all. I have received your emails and will reply as I can.
study well this week.
Exam #3 answers are now posted. Check with me next week if you are still not able to match the answers.
4/5
Matt found a very cool Symmetry site - I have added to the Part 4 webpage.
More lab artwork...click on the image to blow it up...
PS#7 solutions are now online.
4/2/09
Note of changes for the week after spring break_4/13 to 4/17.
During Lab: update to TM complex concentrations
X(CO)y =0.009841 M
X'(CO)y = 0.02797 M
X"(CO)y = 0.008043 M
Slightly different from your lab manual.
3/30
Remember, Tuesday 3/31 is a school holiday. TuTH lab folks, if you want, you may drop by the Wed lab from 9:30 to 11. The experiment ( Paper Chrom ) will be mostly done and the rest of the time devoted to Point Groups.
PS#7 is due on Thursday.
Math and Science Club Movie afternoon: "21" ( Blackjack)
- Good news: At the beginning or after the movie, we will have a guest speaker,
J.P.Massar, graduated from MIT. "21" is a movie about a man who wins
a lot of money at casinos in Las Vegas by using probability. This movie is
based on a real story. J.P. Massar is one of MIT card-counting team's player.
He will show us how to use math in playing Black Jack. Moreover, Mr. Teti,
my Calculus instructor, will be a special guest in this event.
- The ticket is 5$ (including pizza and soda)
- Date: April 2nd, 2009 ( Thursday)
- Time: 3PM-6PM
- Place: Cloud Hall , Room 246

8:30 PM - Solutions to the green sheet are now posted - see comment below.
I just heard that the CCSF scholarship applications deadline has been moved back to 4/17 - see their website.
Squeaky says: "can't you see it? this only has a C4 axis of rotation... so must be C4v"
Black cat replies: "yeah... no sigma h and only 4 signma v's... yawn... can we nap now?"
(cat's from a former student - 101A and 101B and ochem )
3/24 8 PM
Wed lab is cancelled (3/25). Please study for Exam#3, work on the CPR or start on PS#7. Next week's labs do not take the full period, so there will be time to get assistance with symmetry. The Quiz on bonding and symmetry ( not MO theory ) will be 4/21. You are also welcome at the Thursday lab from 12-2 for assistance on PS#7.
PS#5 solutions - links have been fixed.
Green sample questions - solutions will be posted soon. 1d) will give an error on your calculator, so just go through the setup - it is very large - I had to change it during that test and I forgot I had done this ( when I made your review sheet ).
study well and do not get sick...;-)
3/23 11:15 PM
See you in lecture and lab on Tuesday.
3/23 6:50 AM
Sorry for the last minute notice. Monday morning lab is cancelled. Our oldest son woke up sick this morning. I will update this page as to the plans for Tuesday.
MW group, we'll work on point groups on Wed and any last minute questions for Exam #3.
3/18
Now that most people have come by or talked with me about midterm progress... keep up the good work. "The midterm average is about 73% for the class."
Monday - lab will be about "visualizing" structures and learning to identify symmetry using the FLOW chart from lecture. TuTH lab folks, you are welcome to drop by anytime from 9 to 11. There will also be time for questions as you prepare for Exam #3. Tuesday's lab will be similar and MW folks are welcome from 12 to 2. "Think of these times as extended office hours or a very large study group session!"
Tuesday lecture will be on Molecular Orbitals, as we continue to work with covalent bonding... ionic bonding will be after Exam#3 and after the spring recess (in case you were wondering ).
3/17
National Science Foundation - Science and Math majors scholarship. See me or the flyers on the 2nd floor for details. This is a 500 to 5000 dollar scholarship; that is renewable until you transfer. March 27th is the deadline.
If you are missing lecture, then you had better get the notes. This portion ( until we get to the T. M. complexes ) does not have a specific chapter - you use your textbook as a reference; you use me as a reference; you take a look at the books on reserve; you find other resources on your own.
3/15
Midterm Progress - see me at office hours or after lab to discuss your midterm progress. This is based on 2 CPRs, HW, Lab and 2 exams = 400 points. Still half a semester to go, so the "grade" can change by the time you take the final exam.
3/14
You probably have noticed that I have not assigned a problem set for Chapter 11. You are "experienced" enough now, after a semester and half at doing problems. Choose the ones in Chapter 11 that are comprehensive ( thermo and equilibrium related ). Your labs and the CPR will also be a guide as to the preparation for exam#3.
Monday and Tuesday will be another short electrochem experiment/demo. So, I will have a mini-lecture during the lab on electrolysis. The remainder of the lab will be work time - check calculations and to write your CPR text entry.
Tuesday Lecture - we start Descriptive Chemistry - this is the last part of the course and could be the most interesting ( it is for me) for many of you. We'll see. We start of "journey" towards studying Transition Metal Complexes... =)
3/10
For those who missed lecture this morning. Get the notes from someone... we covered a lot of Chapter 11 material and how to approach the calculations in Day 1 of the E. Cells lab.
Also, you missed this incentive - related to Exam #2 and your Final Exam
3/8
We start the electrochemistry material on Monday - chapter 11. We will have 3-4 days of labs related to these topics.
Hope everyone has a great weekend.
3/4 9:21 PM
Students have reported to me, so I hope the rest of the class has caught this:
Error in my key. Problem #2, I forgot to square the ( .125-2x) term. See your
CO2 lab notes for a similar question. The setup is is still correct,
I just plugged into Keq incorrectly. ;-)
Hope the studying has been going well. Get sleep tonight also! =)
3/3
Sample exam question solutions are now posted here and to the bulletin board outside our lab.
"Extra Effort" homework - for those that have missed a previous homework assignment or problem set. Problem Set 5 will be collected at lecture on 3/10 - then I will post solutions for everyone. Problem Set 5 is on this website and on the last page of the THERMO handout from lecture.
Have given extra time for the BORAX lab report, becuase you have an exam this week, but do not put it off for too long. You will have REDOX calcs and electrochem problems to work on very very soon ( next week ).
Study well and get rest before the exam.
2/26
PS#4 solutions are now up. Study well.
2/25 9:35 PM
all is well. See you all in lecture and lab on Thursday 2/26.
Hey, if you are interested... the CCSF Science and Math Club will have a meeting on March 5th in S204. I think from 2-4 PM. Look for flyers being posted.
2/22
Hi All, I heard from a few that I put on the board tthat PS#4 is due on Tuesday but hte website says Thursday. I may have, so we will go with the website. PS #4 is due on Thursday at lecture for everyone.
Glycine lab report is due at your lab on Monday and Tuesday.
CPR Text Entry is later in the week also, but you will have time in lab to work on it.
CPR#1, I am reviewing results now and I made an adjustment. I had the review deviation to "tight" and the self assessment deviation to "loose" , so please check your results again ( sometime ). Some scores went up and some went down within the CPR scoring - it does not directly impact your 25 points possible <- which I am working on right now. ;-)
2/19
Exam #1 solutions are not on the bulletin board. Since you have your exams, please go through them and check what you missed. I will not post the key to the web.
PS#3 solutions are posted to the web and the bulletin board.
CPR#2 is not active, if you want to take a look at it. It is based on a website and the observations you will make in lab next week. If you would like a hard copy of the website, please email or ask me for it.
Next week lecture - we will be talking about Thermo - this IS NOT on Exam #2.
Next week lab - is still ACID/BASE/Solubility equilibria.
Remind me to give you the sample questions. ;-)
Have a great weekend. Email me if you have questions. STUDY well.
2/12 10 PM
I hope the TuTh lab session went smoothly and that everyone got a good data set to plot.
Glycine Lab Report: For your report, I would like you to analyze the curve. Use Excel to plot your points and even have a line connecting them ( interpolate function ). Then, you need to use a ruler to analyze the graph by hand. Be sure to note the equivalence points, the half equivalence points and the corresponding pH's. Problems 1-3 are required. There is also a Bonus question, which I will give in lab ( MW folks already got it ).
Have a great weekend. Rest, relax and then study a little chemistry. ;-)
2/11 Post Exam #1 "blues? "
Need some advice? Make an appt to see me, or email me or ask during lab.
How about hearing from your peers? I have updated their advice page.
2/10
fyi
CPR Scoring for assignment #1 ( not directly for my gradebook )
Text = 14
Calibrations = 24 ( 8 each, done by the deadline )
Reviews = 45 ( 15 each )
Self Assessment = 20
Total = 100
Dr Su's evaluation of your participation; 25 points in my gradebook
Text Entry = 3
Calibrations done = 3
Reviews done = 3
Self-assess
= 3
Check Results = 3 ( within 48 hours of the END time )
Dr Su's EVAL
= 10 ( I look at all your sections above )
Total = 25
As you can see, in the CPR score ( assignment ) the emphasis is on your reviews and self assessment. Recall - "you should know more by the end than when you started."
In my evaluation of your work, ~ 60% is based on your participation with the rest on your learning & peer evals. =)
8:55 AM
No lab today, for the Tuesday group. We will conduct the GCMS prep on a future lab day.
Everyone, work on your CPR - calibrations are available and you must complete them by Friday AM, in order to be qualified to review your peers ( and earn points within the CPR score ). See the handout below.
You also have your Problem Set #3 to work on - that is still due on Thursday.
2/09
11:30 PM - hmmm... only 21 texts entered... guess the rest are going to be up late or up early. ;-)
Still have not heard about a substitute for the 11 AM lab.
--
CPR ratings Guide. Use this handout, as you work on the calibrations. Be aware that there is a calibration due date, and if you should miss it, you will lose points within the CPR score and may lose points in my evaluation of your work at the end.
You can also use it, as you review your peers and your self assessment. It is only a guide. In CPR ratings, nothing is "absolute" except for Dr Su's final points assigned in the grade book. Remember, I see all and evaluate all at the end of the assignment. ;-)
2/09 8:00 PM
Lecture is cancelled on Tuesday 2/10. Stay tuned for more info... check back a few times.
2/6
Exam #1 is over. "Forget about it." You have other things to do and then return back to work on chemistry this weekend.
CPR#1 is now active. You can take the tour and the pretest ( it's not graded points and will give you the answers afterwards ) and then go into the assignment. It is the same as the handout you have ( worksheet ).
PS#3 and PS#4 are posted.
MW LAB folks, you will carry out the glycine experiment on Monday, TuTH will do this on Thursday.
TuTH lab folks will start a "future" experiment on Tuesday, then it's a work day where all are welcome to attend and study.
have a great weekend!!!!
2/4 10 PM
In the scanned key, I have a "typo" - 1a) should have a nuclei with 110 at the Atomic #, not 100. All works out with the addition/subtraction now. ;-)
The binder and bulletin board had the corrections. If you are reading this message tonight - GET some Sleep! =)
2/3
Practice Exam Solutions are now posted here and on the bulletin board. Look to your homework, textbook and lecture notes for specific details - or ask me! ;-)
Study well. Get rest. A one-hour exam but you will get the period ( no lecture afterwards ).
See My Progress for your current assignments, when Exam #1 is done and you have rested.
2/2
Updated Problem Set #2 and Problem Sets #3 and #4. #3 and #4 are for Chapter 7 & 8 ( Exam 2 ).
1/31
Problem Set#1 solutions are now on the Bulletin Board and this website. I will be posting Problem Set #2 solutions on Monday.
1/27
Email Assignment #2 - Login into your CPR account by Friday 1/30/09; 10:00 PM. Email Dr Su that you done this successfully or that you need assistance. I will be checking. ;-)
I have updated the reading assignments for 6th Edition and 5th Edition users.
See My Progress for your current assignments, as you prepare for Exam #1.
Remind me to hand out sample questions - I have them being copied right now.
1/22 - updated 1/23 with TuTH class data.
Hydrolysis Lab report: Make sure you justify your Rate Law for Part I ( reasons
or calculations accepted ); Include the graph for Part II.
The questions at the end of the lab are NOT required for the report or your notebook,
but you should try them as practice for Exam #1.
Semi-formal report is due 2/2 and 2/3 at lab. Even though you worked in pairs during the lab, I expect individual lab reports.

If I have given you add codes for the course, please try registering NOW. If there are any problems we will take care of them on Tuesday. ( Otherwise you might not get in and I will move down to the next person on the waitlist ).
Tuesday Lab section , will check in to lockers - the first experiment will be on Thursday.
MW lab section will check in on Wed and then conduct the first experiment.
The Hydrolysis experiment will be done ALL in one lab period. Be prepared.
1/13/09
Problem Set #1 - problems from the textbook. See the problem set pages. Due at lecture on 1/27.
1/12/09
Homework assignment #1 - this is an easy task ( or tasks )
View the hydrogen bromine animation from Iowa State University ( linked on the 101B page ), see the spinning puzzle piece.
Email Dr Su ( tmsu@ccsf.edu ) by Tuesday 1/20 8 AM, and answer this question, on what you OBSERVE -> "what is the mechanism? " Briefly describe it ( write a short description, explain what you saw in the animation, tell me in your own words... ).
More about this later: Calibrated Peer Review (CPR) assignments are worth 25 points each - The score you receive in the program is not the score that goes into my gradebook. I will evaluate you based on your participation, peer comments and self assessment - you should know more at the end of the assignment (then when you started it). An example of the 25 point breakdown.
1/12/09
Lecture on Tuesday and Thursday, during the labs, on Ch. 15 material. First actual experiment and locker checkin will be next week.
Start reading Chapter 15 on Kinetics. Sections 15.1 to 15.9. Problems will be assigned from the chapter. See your lecture notes and the homework section of this site.
Spring 2009
Happy New Year! Check back often for more announcements. This page is always under construction, sorry for the blah gray background. ;-)
