CHEMISTRY COMMUNITY

Jonathan3B

I'm in a similar position and I'm just gonna give it my all and then move on with my life. I hope for the best but I know to expect the worst, it is what it is tho, I wish you luck tomorrow with your studying!

Jonathan3B

I am in the exact same position, there is just so much to do that I don't even know how to approach it. I have struggled all quarter so I need to review everything EXTENSIVELY but I just don't know how to go about it all :(.

Jonathan3B

Yeah, that's usually how it goes with Lavelle's finals in my experience.

Jonathan3B

That's the plan! I have already received my first dose of the vaccine and should receive the second dose soon, so if all goes well I should be on campus next year.

Jonathan3B

Thank you Dr. Lavelle for being so dedicated and enthusiastic about teaching chemistry! It has been a pleasure taking chem 14A&14B with Dr. Lavelle, I am not taking chemistry next quarter but ill be back eventually...

Jonathan3B

Its up and due Friday of this week.

Jonathan3B

Just reading through the book and taking hand written notes along the way is great because I can always go back to any chapter or topic and get an understanding of what's going on. I wish I could type my notes out to save time but I just have to hand write them, there's no other way for me.

Jonathan3B

Yeah, I would say the finals in Lavelle's classes are usually pretty touch and catch you off guard. This is all just based on the chem 14A final.

Jonathan3B

Its pretty tough but I would say making sure you take care of yourself, making sure you are eating, drinking, and sleeping enough will help you feel more refreshed and ready to work.

Jonathan3B

I did not know this final was also on a Sunday, last quarter's final was rough.

Jonathan3B

This quarter was so much more painful than the last, I desperately need a break ASAP!

Jonathan3B

wow I had no idea, thanks for the heads up.

Jonathan3B

This is so cool haha, exciting stuff!

Jonathan3B

Hannah Chew on Tuesdays 2-4 is always very helpful to learn the material.

Jonathan3B

Not working for me either. Was hoping to do some of the homework tonight.

Jonathan3B

I think going to OH is the only way to review your exams.

Jonathan3B

Definitely the molecule and Lewis structure stuff from last quarter.

Jonathan3B

Everything should be accessible as this website is open to everyone, but only students cant post.

Jonathan3B

I try to do as many as humanly possible, it cant hurt.

Jonathan3B

Step up sessions and workshop meetings that the TA's host are so incredibly useful, I don't know where I would be without them.

Jonathan3B

Both are great and I recommend you go to as many of each as you can. Basically the difference between the two is that a step up session is more in depth and the TA will go over all concepts you should be familiar with, while a workshop is for people who already have a solid understanding of the mate...

Jonathan3B

I have been liking the weekend a lot recently.

Jonathan3B

Sadly the final is cumulative and not just on new material.

Jonathan3B

2 weeks leading up to the test I will attend as many Step up/ Workshop sessions as I can fit in my schedule. Along with the helpful meetings, I will use the sapling assignments and the textbook problems to practice/ master the material.

Jonathan3B

The goal for me is to fix my sleeping schedule because as it is right now, its an absolute mess.

Jonathan3B

I'm currently reading On Earth We're Briefly Gorgeous for my Biotechnology class, and it is actually pretty interesting and enjoyable.

Jonathan3B

You can try emailing your TA and asking for screenshots but they rarely will do that. Your best bet is going to your office hours and going over it with your TA.

Jonathan3B

50% of the total points in this class equal a C- grade. So you need at least 50% of the total points to pass.

Jonathan3B

Well I was going to take it next quarter but I was not able to secure a spot and just decided to go with biology instead next quarter. I am still not sure when Exactly I'm going to take it.

Jonathan3B

The max is 50, nothing over 50 counts.

Jonathan3B

I really appreciate all the tips and advice, Ill be sure to try them! Good luck on the Final!

Jonathan3B

All I know for certain is that 50% of the total points in this class will land you with a C-.

Jonathan3B

Breaking bad is easily my favorite show of all time.

Jonathan3B

As others have mentioned, I think the step up and workshop sessions the TA's host are extremely helpful for understanding key concepts you will likely encounter on the exam.

Jonathan3B

The number one resource is the text book problems in my opinion. If you can do the text book problems confidently you should do great on the exam. Good luck!

Jonathan3B

Did you hear the one about cobalt, radon, and yttrium?
It was CoRnY.

Another chemical symbol-based chemistry joke: cobalt (Co), radon (Rn), and yttrium (Y—yes, it’s a real element).

Jonathan3B

I was actually pretty satisfied with the grade I got even though it was nothing special.

Jonathan3B

I think preparation is the best way to not feel nervous. How nervous can you be when you taking a test on material you studies the past couple of weeks for... well maybe it wont eliminate the jitters but it will secure you a good grade on the exam.

Jonathan3B

I think it might be the same as 14A where 50% if the total point in this class will land you with a c-.

Jonathan3B

Wow this quarter has been speeding by. Soon enough we will be taking the final and finishing the quarter.

Jonathan3B

You might have luck emailing your TA and asking them for your exam in order to use it for review. It does not always work.

Jonathan3B

In N Out is pretty good.

Jonathan3B

I think I am going to take chem 14C but I am still slightly confused on what the difference is.

Jonathan3B

There is absolutely no better resource to study with than the text book problems in my opinion. You will often find textbook problems on professor Lavelle exams, sometimes exactly the same, and sometimes just with different values.

Jonathan3B

I think the grades are down because they are getting updated, not too sure.

Jonathan3B

Really needed this after my MT 1 score lol.

Jonathan3B

YouTube video's are helpful, but honestly there is nothing more helpful then the textbook problems. If you know how to do the textbook problems confidently, you'll do great on the midterm.

Jonathan3B

50% of the total points in this class will land you with a C-.

Jonathan3B

Yeah, I didn't do so well on the first midterm so I'm pretty nervous going into this one.

Jonathan3B

Can never go wrong with Breaking Bad!

Jonathan3B

Yes it will have 4 and 8 point questions, and you can get up to 4 points partial credit om every 8 point question.

Jonathan3B

This will be such a useful tool to study with! Thank you so much for sharing :)

Jonathan3B

I don't know, because no matter how much or how hard I study I have not gotten the grades I wanted on the previous midterms. So the standards aren't very high, but I know I am doing my best and there is not much else I can do.

Jonathan3B

I noticed many questions on previous exams we have taken that were straight out of the text book with different values/ variable. So yes the text book is a great tool to get familiar with the questions likely to be on the final.

Jonathan3B

Yes, you should know the list of strong acids and bases, as this will help you greatly with acid and base questions. Anything that is not in the lists of strong acids and bases is either a weak acid/base or neutral.

Jonathan3B

Thanks for the kind words and motivation, hoping we all do great on this final :)

Jonathan3B

Yes it will be cumulative, relative to the amount of time we spent on it. So early/ late quantum will be pretty prevalent will everything else sprinkled in.

Jonathan3B

Based on the previous mid-terms, yes a lot of the questions found in the book have been on our tests so I would recommend you get familiar with them.

Jonathan3B

He said it will be the same format as the previous mid-terms so I take it that it will be multiple choice only.

Jonathan3B

I think the text book has more relevant questions that will probably show up on the exam. I would say do as many text book problems as you can to ensure you will know how to do them if you encounter them on the final.

Jonathan3B

This is very kind of you, thank you so much!

Jonathan3B

Yes the scores have been released today. You can check them on CCLE or MyUCLA.

Jonathan3B

It is just the amount of point you earned out of 500 at the end of the quarter, but I have heard that the class average plays a part in final grades.

Jonathan3B

Yup, very worried. I think many people are doing very good in this class so I am afraid the high class average will affect my grade negatively.

Jonathan3B

Going on evening walks while listening to some music is very calm and relaxing.

Jonathan3B

It sucks because I thought I did great, even better than the last midterm, but I checked my score today and... it was not a pretty sight to see.

Jonathan3B

He is pretty good with giving us time before the tests to learn the material so I wouldn't worry about it too much.

Jonathan3B

Yes they have changed, I start studying for an exam about 2 weeks before to avoid cramming. I am still not getting the grades I want though.

Jonathan3B

I have heard December 11th. I think Lavelle will let us know the exact date soon though.

Jonathan3B

The UA sessions are very helpful, but also I would advise against cramming. Start studying a long time before the exam to avoid time being an issue. BTW Hannah Chew's step up sessions on Tuesdays are extremely helpful.

Jonathan3B

Well... they are out, I am very disappointed in myself to say the least lol.

Jonathan3B

ms will always be either -1/2 or 1/2. I recommend looking up a video on YouTube on quantum numbers, I did it and it was very useful.

Jonathan3B

The last 8 bullet point of outline 2 should be on this midterm since Dr. Lavelle said everything after midterm 1 up to outline 3 will be on the second midterm.

Jonathan3B

Electronegativity increases from the left to right and down to top.

Jonathan3B

lectures from 10/23 to 11/11. so #10-18

Jonathan3B

A lewis base donates electrons in a chemical reaction while lewis acids accept electrons.

Jonathan3B

If I need assistance on a concept or topic I am not quite understanding, I will go on YouTube and look up any videos "Organic chemistry tutor" has mad on the topic and take notes. I will more often than not understand the topic/ concept a little better than before.

Jonathan3B

Q:Why did the white bear dissolve in water?
A:Because it was polar.

Jonathan3B

Larger atomic radius=longer bond length

Jonathan3B

I wish I did just a little better on the first midterm, but other than that I'm feeling pretty good about it.

Jonathan3B

I think he meant only Wednesday discussions, but just to make sure I would try to join your discussion meeting whenever it is to be safe.

Jonathan3B

I don't think we really know for sure, but I'm thinking we will get a grade based on the total number of posts rather than when we posted.

Jonathan3B

Breaking Bad all day every day.

Jonathan3B

The few step up sessions I have been to, have been very useful and allowed me to get a deeper understanding of the material.

Jonathan3B

He just sent out an email saying that we should get our score by Thursday this week.

Jonathan3B

From what I've heard, it will be anywhere from 10-30 questions. Multiple choice with some conceptual questions, so not all questions will require work to be done.

Jonathan3B

I remember the lyman series is n=1 because a lower case l is very similar to a 1. I remember the Balmer series is n=2 by thinking about how the B in Balmer is the 2nd letter in the alphabet.

Jonathan3B

I enjoy playing video games or watching YouTube, but only after I am done doing my work because if not I will feel very guilty about it.

Jonathan3B

The Balmer series is any situation where NFinal, or the ending energy level is n=2, and the same concept is applies to the Lyman series except instead of Nfinal being n=2 it is n=1. I t is also good to know that the Lyman series is UV while the Balmer series is Visible light.

Jonathan3B

Yes they do, higher frequency directly correlates to higher energy. If an electromagnetic wave has high frequency it is also a high energy wave.

Jonathan3B

Compile a list of every topic covered so far and from that list mark the ones you are struggling with or not understanding. Watch a YouTube video on each one of those topics, take notes on the videos, and then do practice problems until you feel confident in your understanding of the topic. Do this ...

Jonathan3B

I am also struggling to stay on top of things, so what I am doing to study is watching YouTube videos on each topic he covered, taking notes, and doing some practice problems to ensure I know what I am doing. Lavelle's videos are very useful but sometimes I get confused and I am unable to ask questi...

Jonathan3B

Yes, the book is a very good source that you should use, but on top of that I would recommend watching YouTube videos on material you are struggling with. Take notes while you watch these videos then turn to the book to do some practice problems. Do this for every subject that we have covered so far...

Jonathan3B

I would recommend you wait until the final answer as doing this in the middle of a problem can lead to confusion and may cause your answer to be slightly off.

Jonathan3B

I think the general rule of thumb is to wait until you have your final answer to round. This ensures you get the most accurate answer.

Jonathan3B

Since molecular equations are basically some sort of multiple of the empirical equation, find out what that multiple is (should be fairly easy given you have both equations) and then divide the molar mass of the molecular equation by that multiple and if it equals the molar mass of the empirical equ...

Jonathan3B

Yeah I think it's 11:59/12 on Sunday night. If not I would still play it safe and have it done before Monday.

Jonathan3B

I like to make a sort of table with the amount of molecules of the reactants on the left side and the amount of molecules of products on the right side. I will update the numbers in the table as I go so all the information I need is organized and clean.

Jonathan3B

From what I've heard from my TA, during exams everything we need such as chemical name/ formula will be given to us.

Jonathan3B

Usually weather you put in the precise molar mass (EX: O-15.99), round it ( EX: O from 15.99 to 16), or "simplify" it (EX: O from 15.99 to 15.9) you will still be able to get the correct answer, so I think its up to personal preference and the specific molar mass. So for me I will enter C ...
