Practice FINAL EXAM

We picked around 11 to 15 questions off of each exam and made a 50 question practice final exam. Below are two versions. The first is not scrambled and exam1 is first, then 2, and so on. The second is totally scrambled which is how we actually deliver the final exam.

Below are some submitted Chemistry Memes

These are really pretty good / spot on. Also, remember a +2 on your Final Exam for a submission on Canvas.







Deadline is Tonight! (5/14)

Extra 2 points on final exam? Do this "assignment": Extra Credit - Creative Chemistry Memes, Comics, etc

Remember: the deadline is 11:59pm on Tuesday

I've started looking through these and I have to say "bravo" so far. I've found something you are definitely good at (as opposed to acid/base theory). Keep 'em coming. I'll post a folder of them soon here on this site.
- Dr. McCord

I made a practice set of questions on chem101. I matched the number of questions on the exam at 25. So this is a pretty good practice exam. When you think you are all studied up... Open the practice set on electrochemistry and see how long it take you to get through 25 questions. A good trial run for the exam. Do the questions perfectly match up with the exam? No. But know that the topics, calculations, and concepts DO match up nicely.

New Battery Section on Review Page

Please LOOK again at my Exam 4 link below. I've added a section on batteries and also added one more learning outcome about the alkaline cell.


Here's a helpful pdf made by Dr. Anderson with several external links to YouTube videos by the prolific Tyler DeWitt. Oxidation Numbers and Redox Reactions.pdf

And... another great set to watch: Tyler DeWitt - Electrochemical cells.pdf.

Hey, here is that cute oil rig that was submitted by a student back in 2014. The student (Jacob Byerly) sketched it in his notes and then I got it and colorized it. So oil rigs can be cute, right?


Canvas Assignments - Unit 4


There are 3 new practice sets on the chem101 app/site to help you prepare for Exam 3. The sets are

  • Solubility (10 questions)
  • Kinetics (20 questions)
  • Nuclear (10 questions)

There is also a review problem pdf available under "Extra Practice" from the MWF classes.


Decay directions on Band of Stability Diagram

The figure shows a portion (Z between 56 and 77) of the band of stability diagram from our gchem website (same as Wikipedia). Note that this diagram has #neutrons as the y-axis and #protons (atomic number) as the x-axis.

The colored arrows on the diagram represent the transitions for beta decay (yellow), positron emission (pink), and alpha decay (green).

The beta decay and positron emission decays always head directly towards the center black boxes which are the stable nuclides. So beta decay is "one diagonal" (right 1, down 1, ↘︎) towards the stability band while positron emission is the opposite direction (left 1, up 1, ↖︎)

The alpha decays track back 2 protons and 2 neutrons which is "two diagonals" (right 2, down 2, ↙︎) on the diagram.

Notice how any given "unstable" nuclide will decay to another, and then that to another, and so on. This is what is termed a multiple decay process or "chain". Ultimately, you end up at a stable (black) nuclide on the band of stability.



Canvas Assignments - Unit 3


Reminder: Drop Deadline is Monday, 4/8


Canvas Assignments - Unit 2

Notice: on #4 on HW07... pick the choice with the 3 ions Na+, H+, and CO32- to get credit. This way, it will be counted correct... It is not actually correct though. The bicarbonate ion (HCO3-) stays that way. I'd prefer to delete the question because it is bad, but Canvas does not work that way. So I'm telling you the "answer". Even if we fixed this, it wouldn't work for you. So just do this and move on.

I will be a faculty panelist at this event today at 3pm. I have no idea what to expect - but I do know that I'll say something.

Voices of Integrity - Senate of College Council's Academic Integrity Committee

Do you think there is more to integrity than not cheating? Are you interested in holding challenging discussions with professors and specialists on the topic? Do you like free food and a chance to win gift cards at a door prize drawing? If so, join us for the Voices of Integrity professor panel this Wednesday in SAC 2.302 from 3-5. This event will be Q&A format with set questions and open questions from the audience. Bring your questions and thinking cap!

Wednesday, March 6 at 3:00pm to 5:00pm

Here is a pdf about the BDP

Credit for "II Only" on Exam 1

Update on granting credit: Once again, this about the "normal boiling point" problem. The question about picking the true statements about the normal boiling point. We are graciously allowing the original "correct" answer to stay that way because it includes the right choice. We asked Quest to also grant credit for the solo choice of "II only" which is in fact the only correct choice of those listed. Remember that "applied pressure" is NOT necessarily equal to 1 atm which would be the definition of "normal" boiling point.

Quest admins DID fix this yesterday at about 12 noon (during my classes). So please check now and make sure if you bubbled "II only" (check your tally sheet on Quest). When manually fixed your question in the tally should look like this:

##
<choice>
X
1/1
5

Where ## is the question number <choice> and is your choice (the "II only" choice). Note that it still has the X but the points earned shows as 5. We are told they fixed all of them.

Still not credited? Please email Amanda so she can look and see your status and manually fix if it still isn't. Please don't make her look if you didn't actually make that choice.


I forgot I updated the Valentines Video that I showed last year. It is slightly different than the one I showed at the very end. I think is is even cuter. Have a look and make a comment if you want. - Dr McCord

Solutions pdfs for Exam 1 are on Quest Now

We have released the exam 1 solution pdfs and tallies to all students now. Login to Quest to view your exam copy pdf with the key and solution explanations given.

The CREDIT discussed below has now been updated in Quest!

Before you Send that Email! Read this about the "normal boiling point" problem. The question about picking the true statements about the normal boiling point. The problem was handled in a most unfortunate way in that there is really only ONE choice that is correct - Statement II about the free energies being equal is the only true statement. Statement I is not correct. The "applied pressure" is NOT necessarily equal to 1 atm which would be the definition of "normal" boiling point. None-the-less, because of statements made by TAs and proctors during the exam, we are still allowing the choice of I and II as being "correct". Statements III and IV are completely wrong and no credit will be given for any choice containing them.

So, IF you are one of those students that chose "II only" as the answer. You WILL be granted back 5 points on the exam. The Quest admin folks have to manually do this and it will take some time. I'll post again when they tell me they have completed the task. So hang tight and you will get 5 points more added to your score. It will show up as a "manually set" score for you on that problem at 5 points.

Make sure you go to the right room according to your letter or face an exam penalty.

Feeling a Tad Overwhelmed about CH301 Content?

If you feel like maybe you've forgotten some major content/concepts from CH301, you might want to spend some time refreshing your knowledge. The following is being shared with all CH302 classes. This is basically a set of direct links to the gchem site on those topics. I personally think the stoichiometry and thermo are the most important parts - but there are others that do come into play. Dr. Biberdorf wrote this up but I concur with her on the need to review.

There are even special reviews coming up from Jimmy, Albert, and Amanda to help you remember. See bottom of page on the link.

I am not using Reef this semester - so do not purchase Reef. Instead, I am using chem101 for in-class polling. They are offering chem101 at $15 for the semester (same as Reef). So all McCord students will need to purchase a chem101 subscription and setup an account with them.

Textbook Questions? Here is a whole page on that. Give it a look if you are concerned: Buying a Textbook for CH301 and CH302 - some things you should consider and know.

NOTE: the gchem site IS your textbook (read the syllabus)

No, I do NOT use the course-pack that they sell over in the UT Coop. Feel free to return yours and get your money back.

Greetings...

Yes, this is my official website for CH302 for spring 2019. Click around if you want. Come to class on Tuesday (1/22) and find out more. Time to get this party started.
