How are you guys going to be studying for the final I'm planning to look over the study guide Dr. Lavelle sent out, do the endgame worksheet Lyndon posted, and review my notes/ do practice hw problems. Also some UAs released another set of practice problems! https://lavelle.chem.ucla.edu/forum/view...

Naren_Ramesh_4F

Is the final still going to be on Sunday and is there going to be a time limit to taking it?

Naren_Ramesh_4F

Will there be answers posted for this worksheet?

“Earthquake” - FINAL REVIEW SESSION Search “Earthquake” to find this post. Hello, I am organizing a review session on Friday March 13 from 6:00-9:00 pm in the Sunset Village Delta Terrace House 6 Lounge. We will meet in the lounge and go over problems on the whiteboard from the ENDGAME worksheet, a...

Naren_Ramesh_4F

Thank you so much Lyndon! Without your review sessions and your great worksheets, Chemistry 14A and B would have been so much worse. Because of the nature of the cancellations, will there be an answer key that will be posted?

Apparently not though. I think the OP should confirm with the professor or a TA and let us know.

Naren_Ramesh_4F

Yea, I think you should play it safe and aim for 50 this quarter instead of trying to cumulate all your posts from both quarters.

Naren_Ramesh_4F

I think the equations sheet on Lavelle's website is the one we will get for the midterm and the final. I thought that too but there are some discrepancies between the sheet we get during the test and the sheet on the website. For example, on the website, the conversion of a Volt is there but it was...

Naren_Ramesh_4F

Will there be any curve or anything of that nature on this Test?

Naren_Ramesh_4F

To anyone who attended, I would really appreciate it as well.

Naren_Ramesh_4F

Are there any review sessions that UA's will be hosting for Test 2?

Naren_Ramesh_4F

Attend lectures, Attend Discussion, and DEFINITELY Attend TA/UA sessions

Naren_Ramesh_4F

I was more wondering how theories like The Big Crunch are plausible if the disorder of the universe is constantly increasing.

Naren_Ramesh_4F

My TA said you should expect a similar amount of problems but I would assume that the length of the problems may be different. The questions from electrochemistry seem to be longer and more complex hello in terms of understanding balancing redox reactions and then applying this concept to galvanic ...

Actually, I've heard that Test 2 is much harder than Test 1.

Naren_Ramesh_4F

Thank you all so much for your advice. I'll probably take 14A-D before I tackle the labs. Thanks again!

Naren_Ramesh_4F

There are no extra credit opportunities historically in Prof Lavelle's 14 series classes.

Naren_Ramesh_4F

He has a "Grade adjustment period" at the end of the quarter. So the class gets curved slightly at the end.

Naren_Ramesh_4F

Does Lavelle ever pull out questions from Sapling Learning for the exam/midterm?

Naren_Ramesh_4F

Do you guys know when the test is?

Naren_Ramesh_4F

There is a thread on the Administrative Questions section that answers this question. The general consensus is that you can turn in problems from outlines on the midterm.

Naren_Ramesh_4F

My TA said that she would accept midterm outline problems. I don't think it really matters what outline you do for this week as long as it is sort of relevant given the lack of new content this past week.

Naren_Ramesh_4F

I was wondering what the recommended pathway is for taking the chem series, specifically the labs. Is it better to take the 14BL and CL after finishing the series or taking BL after B and CL after C?

Naren_Ramesh_4F

Yea, there is a "Grade Adjustment Period," where grades are adjusted based on the class average from what I understand.

Naren_Ramesh_4F

Yea, I too was really surprised by the amount of content-application we had to use instead of problems we had worked with in class. Ultimately, there is no better way to studying for these problems than being really solid with the fundamentals of the section, which comes from doing a ton of practice...

Naren_Ramesh_4F

Do you know if UAs or Tas post their slides or worksheets on chemistry community from all their review sessions and step up sessions?

Is the .15 in 273.15 important enough to include in sig fig calculations when converting between K and C?

Naren_Ramesh_4F

This is a great resource! Thank you! Are there similar ppts for other review sessions?

Naren_Ramesh_4F

Will the answer key be posted on Chemistry Community?

What are the key search words for the UA worksheet for this midterm?

Because water is a polar molecule.

If entropy of the universe always increases with any reaction, what are the implications for the fate of the universe?

Naren_Ramesh_4F

Historically, the professor has never given out extra credit.

Naren_Ramesh_4F

One trick I used last quarter to find the worksheets TAs and UAs post on Chem Community is to simply search “download” or “worksheet.” Chemistry Community will show you worksheets that people post.

If we couldn't pick them up during Week 3, is it too late to pick them up in Week 4?

Naren_Ramesh_4F

I'd recommend going to the UA and TA sessions because they have worksheets that you can't find on Chemistry Community or anywhere else.

Naren_Ramesh_4F

So will we get a 50/50 if we have a 100 posts in total or just 50 this quarter.

Naren_Ramesh_4F

How does the difficulty of Sapling problems compare to textbook problems?

Naren_Ramesh_4F

In addition, tests are worth 50 points while the midterm is worth 120 points.

Naren_Ramesh_4F

I think your grade is determined by how many posts you make overall in the quarter. They say weekly but last quarter I forgot to post one week and I still got full credit as well. As long as you post 50 times this quarter, I think you should be good!

Naren_Ramesh_4F

Will there be lecture notes posted for week 2 as well? I find these notes to be a great supplement to what I took in class and very helpful overall. Thanks!

Thank you so much everyone!

Cool! Thank you so much!

Naren_Ramesh_4F

I will be unable to make the lecture for 1/13. I was wondering if anyone would be willing to send me or upload their notes from that lecture? Thank you so much!

Naren_Ramesh_4F

I would like to add that with Professor Lavelle, anything mentioned in lectures is fair game to be on tests, midterms, or the final. So, I would remember this just in case it pops up on something big.

Dina 2k wrote:Also, are the peer learning worksheets the same each week?

I believe the TA/UAs that are in charge of the peer leaning sessions change the worksheets every week to encompass the curriculum taught that week.

Naren_Ramesh_4F

Does anyone know which outlines will be covered on the test in 2 weeks?

Naren_Ramesh_4F

When are Chemistry Community answers due?

Naren_Ramesh_4F

When asked the equilibrium constant of a chemical reaction involving gases, do we solve for Kc or Kp?

Naren_Ramesh_4F

On the outline, it mentions that we need to know well-known examples of coord compounds used as chemotherapy drugs. Other than cis and transplantin, what are some others we need to know?

Naren_Ramesh_4F

On question 2b of the mini marshmallow, does the order of the ligand in the coordination complex matter?

Naren_Ramesh_4F

I think the best way to approach this if you are having difficulty is to memorize the common polydentates like oxalate and ethylenediamine.

Naren_Ramesh_4F

Hello everyone! Because Thanksgiving is situated in Week 9 this year, and your final is this upcoming Sunday, I will unfortunately not be able to hold one last workshop with you all. However, I have attached my notes for coordination compounds as well as acid/base structures (the ones I usually wri...

Does anyone know when the answers for this packet will be given?

Naren_Ramesh_4F

Yep, it is definitely cumulative covering topics from HS Fundamentals to topics covered in Week 10. Good luck!

Naren_Ramesh_4F

From what I’ve heard, it is dependent on your TA’s policy on grading Chemistry Community. I think you should consult your TA to find out.

Naren_Ramesh_4F

Honestly I think any topic after the second test is fair game. Especially because both the homework’s can be turned in during Week 10.

Naren_Ramesh_4F

Is there a specific naming convention for the metal anions that end in -ate? For example, why is the Nickel anion nickelate and not nickate but the cobalt anion is cobate and not cobaltate?

Naren_Ramesh_4F

Does anyone have a list of chart of common ligands that we should know before the final?

Naren_Ramesh_4F

Is there any practical application to viscosity like do yall know if there are any formulas that factor in viscosity or is it more just a property of certain substances to be aware of in general knowledge?

I found this really helpful for visualizing the bonds! Thank you!

Naren_Ramesh_4F

I personally would recommend going over the textbook. Although there are some topics are not covered in the scope of the class, the textbook presents a different way of looking at a concept.

Naren_Ramesh_4F

I concur with my peers. It is indeed cumulative.

Naren_Ramesh_4F

Most upper class men have told me that it is best to do Chem 14BL after taking Chem 14B. If I were you, I would wait until after 14B to take the lab just to stay on the cautionary side.

Naren_Ramesh_4F

I believe Dr. Lavelle will be going over it in the 11/18 lecture.

Naren_Ramesh_4F

Yea, it is until the lecture on 11/18 when the professor talks about Pi and Sigma bonds.

Naren_Ramesh_4F

What room in Covel is the study session in?

Naren_Ramesh_4F

From what I understand it will cover everything in our lectures from our midterm to 11/18

Naren_Ramesh_4F

Honestly any of those AP Chemistry reviews in one hour type videos are really helpful for refreshing your memory and getting a general overview.

Naren_Ramesh_4F

Salt is sodium funny!

Naren_Ramesh_4F

How do you know if something is a biradical molecule though? The adding valence electrons to get an odd number doesn't exactly work with biradicals right?

Rebekah Alfred 1L wrote:This chart that compares sigma bonds and pi bonds could be helpful to you!

Wow this really helped! Thank you so much!

Naren_Ramesh_4F

Wait so is it cumulative or just on the topics we learn after the midterm. Different people are saying different things. Is it possible to hear from a TA or UA? Thanks!

Naren_Ramesh_4F

Will we need to know this topic for the final or for any other classes in the Chem 14 series?

Naren_Ramesh_4F

I know our TA was sick last discussion section. For the next discussion section, do we have to turn in two sets of homework because we missed last week's hw?

Naren_Ramesh_4F

Is there any way to see the answers to the midterm questions before the grades get released? I'm so nervous and I want to get a good estimate of my score.

Naren_Ramesh_4F

I thought this paper was pretty interesting:

Naren_Ramesh_4F

Does anyone know who grades our midterms? Is it our specific TA or any TA?

Naren_Ramesh_4F

I just wanted to thank the TA who made this because I found this to be an awesome resource for studying. Thank you so much!

Naren_Ramesh_4F

Actually I think it starts at 10 nm.

Naren_Ramesh_4F

I think it is also important to know that schrodingers equation yields for numerous answers which signifies the different types of orbitals and the uncertainty of electron position.

Naren_Ramesh_4F

I don't trust atoms, they make everything up.

Naren_Ramesh_4F

Are the grades curved at the end of the quarter or is it just based on points?

Naren_Ramesh_4F

Are sections that the professor doesn't pull questions from fair game for the midterm?

Naren_Ramesh_4F

Will the midterm be graded on the curve or just based on score?

Naren_Ramesh_4F

Are the old tests in the Student Activity Center a good resource for studying for midterms?

Naren_Ramesh_4F

Is it possible to see where you have posted so far?

Naren_Ramesh_4F

The coffee place with the sign that says "Jews for Jesus" is a great place to study too. The coffee is pay what you want.

How do TA's find students to give credit?

Naren_Ramesh_4F

Are there any differences between periodic tables? Does it really matter if you bring your own?

Naren_Ramesh_4F

Awesome advice! What major were you as an undergraduate if you don't mind me asking?

Naren_Ramesh_4F

I also try to review my notes for the class and try to find relevant sections in the textbook and take notes on that as well.

Naren_Ramesh_4F

Does anyone know how frequently grades are updated and also how long it usually takes for tests/mid-terms to be posted on myUCLA?

Naren_Ramesh_4F

I also found a hydro flask and left it at the front of the class on the lecture desk on Monday. The hydro flask was light blue if that helps the owner.

Naren_Ramesh_4F

Yes, I recall the professor saying that the posts are due on Sunday at midnight as well.

Naren_Ramesh_4F

I am definitely interested as well! Thanks!

Naren_Ramesh_4F

After the test grades are up, will we be able to look at what we got right/wrong?
