I work full time so I don't have much time to study. I am panicking because im super bad at chem even though it is the class I work the hardest for. I was wondering if anybody has any advice and study tips? I will be spending all day of saturday studying.

Jaclyn Dang 3B

same I am holding on for dear life and talking to the universe at this point haha. just hang in there, we can do this.

Jaclyn Dang 3B

I hope so, I know a lot of people change their schedules around so hopefully I can try to get a spot on the waitlist.

Jaclyn Dang 3B

although he doesnt curve he does offer bonus points, which is basically like a curve

Jaclyn Dang 3B

I work 30 hours a week, tuesday, wednesday and friday from 9am-7pm. I try dedicate 3 full days to catching up on lecture and assignments and then one day to relax.

Jaclyn Dang 3B

The chem 14A final completely threw me. I remember I got 100% on midterm 1 and 92 on midterm two and the final I got like a D-. I would say expect the final to be way harder. attend more sessions and redo the questions again.

Jaclyn Dang 3B

commenting so I can go back and review this question later because I was curious as well. haha sorry I couldn't help more.

Jaclyn Dang 3B

Only the official equation sheet on the website.

Jaclyn Dang 3B

it depends on the requirement you are trying to fill, but Psych, Classics, and Scand have some easy classes.

Jaclyn Dang 3B

q will equal h when here is no expansion work and and pressure is constant.

Jaclyn Dang 3B

No work is a force over a distance while heat is energy that is transferred as a result of temperature difference. Internal energy is both U= w+q.

Jaclyn Dang 3B

Try visiting the class website and looking at outline 3 and 4

Jaclyn Dang 3B

I am on the same boat with 14BL, idk how I am gonna get in

Jaclyn Dang 3B

WOW, this saved me. I was am stressing for this midterm since I didn't do as well as hoped for the last midterm.

Jaclyn Dang 3B

Download "Atkins" into your computer. it has all of the solutions. keep in mind some of them have errors, for the ones with errors i believe professor sent an email with the corrections, or it is on the class website.

Jaclyn Dang 3B

Hi! I had lavelle for 14A, 50% of points is a C or C- I believe and then just calculate the rest out of total points to get the percent or letter grade you are looking for.

Jaclyn Dang 3B

In person labs are for sure way longer, I personally like online labs because I'm lazy, but its all personal preference.

Jaclyn Dang 3B

I like to talk out loud and repeat the process of the problem when I am doing homework

Jaclyn Dang 3B

I am going to do the practice questions for the text book and read the textbook as well as go over my notes from class.

Jaclyn Dang 3B

Chem 14C, 14BL and physics 5C

Jaclyn Dang 3B

I would say first

Jaclyn Dang 3B

Hi guys im panicking to the point of depression. I did so so bad on the exam. When I saw that the class average was so high, I almost died because I did so bad. For those who are successful this quarter, how are you guys staying successful? I was successful in 14A by doing the textbook practice prob...

Jaclyn Dang 3B

Lavelle usually does not curve since the exam scores are typically high. Last quarter he did add 10 points to the final exam for everyone though!

Jaclyn Dang 3B

I am taking BL in the summer and then doing CL in the spring

Jaclyn Dang 3B

I heard that it was really manageable since being online. I am not sure however if there are synchronous meetings.

Jaclyn Dang 3B

I have a feeling it will be outline 3 4 and possibly a portion of 5. More informaiton is usually released a week before

Jaclyn Dang 3B

steam is hotter than boiling water

Jaclyn Dang 3B

I have 22/25 but shouldn't there only be 20 posts? since its up to week 4 not week 5

Jaclyn Dang 3B

Will these values be given to us or would we have to memorize them?

Jaclyn Dang 3B

My planner for Spring Quarter opened up and I saw that there is only 2 classes of Ochem classes, will there be more classes later since there is like 900 students in 14B right now?

Jaclyn Dang 3B

Last quarter all the questions where multiple choice, but I am told there might me some fill in the blank as well, so Id have sig figs just in case.

Jaclyn Dang 3B

You just need to install the program. I think your TA might make a mini quiz to test it out too like mine did.

Jaclyn Dang 3B

scratch paper is allowed but it has to be held up at the beginning of the exam

Jaclyn Dang 3B

I believe so, make sure to have your phone charged :)

Jaclyn Dang 3B

textbook questions pretty much resemble the exam questions. For content or like a refresher, I go to UA sessions. Towards the exam, I review the textbook questions again along with sapling.

Jaclyn Dang 3B

Because NH3 is a product, it gains 0.2 so it becomes 0.2+x, not 0.2-x. NH4HS is a solid so it is left out of the equation for K. Hope this helps.

Jaclyn Dang 3B

It is probably the same exact format as 14A. The amount of questions and point breakdown will probably be given to us later as we approach the date.

Jaclyn Dang 3B

Im taking 20 units this quarter and I have found it super useful to take breaks between recorded lectures and assignments. For example, I will do 50 mins of work and then 10 mins of free time. After 4 hours, I get 30 mins -1hr of free time

Jaclyn Dang 3B

Its a typo, theres a solutions manual pdf somewhere that corrects it.

Jaclyn Dang 3B

I think outline 1,2 and 3, but of course it is subject to change.

Jaclyn Dang 3B

The inert gas does not react in the reaction because it doesnt affect any of the products or reactants. therefore it K is unchanged.

Jaclyn Dang 3B

I usually think of using ice when the problem gives you an initial concentration and ask you to determine the final concentration at equilibrium. Hope this helps.

Jaclyn Dang 3B

Q is at any time and they are calculated the same exact way. You would measure Q at that moment to determine the direction of the reaction. if Q=K then the reaction is at equilibrium If Q<K, the reaction is going right and it favors products If Q>K, the reaction is going left and it favors reactants

Jaclyn Dang 3B

watch all the lectures, read the textbook and do practice problems

Jaclyn Dang 3B

I love clueless, fast and furious and harry potter. I always have those as a background noise.

Jaclyn Dang 3B

Dr. Lavelle often starts small and builds up on topics whether you remember them or not! he does not make the assumption that all students have learned the material (even though most of us were in his class) rather than he takes his time to reintroduce it. Don't be too worried about reviewing.

Jaclyn Dang 3B

As said above, I believe C is wrong. There is a reaction, however there is Not net reaction because the forward and reverse reaction occur at the same rate.

Jaclyn Dang 3B

I review all of the outlines and read the textbook. I found that lecture and sapling homework is not enough for me to remember the content, so I read the textbook and take some notes. In addition, I practice the study problems and go one at least one stepup sessiona week.

Jaclyn Dang 3B

These are just optional and are not graded. The ones that are graded are the weekly ones .

Jaclyn Dang 3B

The textbook is not required, but it is super helpful if you forgot a topic or need extra coverage. I tend to read it even if I don't need extra help.

Jaclyn Dang 3B

I would memorize them and memorize the factors that make strong acids and bases.

Jaclyn Dang 3B

Hi, I asked my TA about this in discussion. They said some will come from the textbook, but not necessarily all of them.

Jaclyn Dang 3B

The final is cumulative. There are 30 questions, six points each and the content is going to be based off what we spent the most time on.

Jaclyn Dang 3B

As said before, we just need to know that four is either tetrahedral or square planar, but no need to distinguish between them.

Jaclyn Dang 3B

Im going back and doing all of the problems from the outlines again cause I forgot them all and thought it'd be good practice

Jaclyn Dang 3B

It is stated that the ligands are in alphabetical order if that helps!

Jaclyn Dang 3B

Go to the UA sessions, they help! I like going to hannahs session, shes super nice and really helpful. I also read the textbook just to fimilarize myself with the material again . After all that, I practice textbook problems.

Jaclyn Dang 3B

In addition to what is said above, I remember something about Dr. Lavelle stating that the final is only 1 hr and 30 mins, not the full 3 hours.

Jaclyn Dang 3B

stressed cause finals are creeping up and all the work for my classes apparently wants to fall in under week 10 and that was the week I was planning on studying for finals.

Jaclyn Dang 3B

Isn't the structure the same as to where there are only two exams for 14B? Also Id be okay with a conflict as long as the other class is asynchronous, but thats just me.

Jaclyn Dang 3B

NOT A CHEM 14B OR CHEM14A QUESTION

have you guys heard any rumors of getting off the waitlist for chem14bl, there are spots however they dont fit with my schedule and I was wondering how easy it is to get a spot off the waitlist.

Jaclyn Dang 3B

As said before, used flash cards! I like to make my own using quizlet or I use somebody else's quizlet

Jaclyn Dang 3B

I think Im going to take it together just because I happen to despise labs and I dont want to deal with it later on.

Jaclyn Dang 3B

I thought it was just a point system and in the end whatever you have out of 500 will be your grade...

Jaclyn Dang 3B

Relax and breathe before taking the exam. Sit at your desk a little earlier than the final time so that you can mentally prepare yourself. I like to mentally tell myself "I can do this, imma get an A" lol it seems to kinda work.

Jaclyn Dang 3B

Okay so I am just wondering why there are about 930 spots for chem 14A this quarter (fall 2020) and there are only roughly 705 for next quarter (winter 2021). What about the other 230 students? Im a sophomore and I really need the class and now im sad :( I was on the brink of tears watching this cla...

Jaclyn Dang 3B

I exercise my body by going to work (I work shipment for retail) I also used to go to the gym before it closed down in my area.

Jaclyn Dang 3B

Are lewis acids and bases going to be on this exam?

Jaclyn Dang 3B

Its probably going to be posted a little later since most of us a preoccupied with studying for midterms.You are right that there is a sapling every week :)

Jaclyn Dang 3B

In short, when the bond interaction strength increases, so does the boiling point. In addition if the amount of bond interactions is high, such as van der waals with a rod shaped molecule instead of a spherical one, the boiling point will be higher as well

Jaclyn Dang 3B

The 100, Greys Anatomy, Psych, Friends, How I met Your Mother, Dynasty,and Avatar the last airbender.

Jaclyn Dang 3B

You are right in the fact that you look at how far away they are. I had trouble with this one too they they seem almost the same. Hope this helps.

Jaclyn Dang 3B

I've been stressed too, just remember to have a growth mindset and mentally prepare yourself when taking an exam. I found that this works when I feel like im unprepared even though I've studied and done everything that I needed to. Trust the process :)

Jaclyn Dang 3B

Are the amount of questions on midterm 2 going to be roughly the same amount as the amount of questions on midterm 1?

Jaclyn Dang 3B

I've heard that chem 14bl is an overwhelming amount of work and it would be better to take it separate from chem 14b. If you're unsure there are also bruinwalk reviews on what other students chose to take. Keep in mind the reviews may be precovid and online classes.

Jaclyn Dang 3B

Electron affinity is the measurement of how attracted it another electron. Also known as how likely it is to gain electrons to complete its octet. An important trend to realize is that it increases as you go to the right and up the periodic table.

Jaclyn Dang 3B

Aw thanks for checking in thats so sweet! Honestly, im struggling lol especially with my Physics class. Things are difficult since its hard to interact and meet new people. Even clubs aren't as interactive. This class is honestly my favorite class this quarter and if anybody wants to make a group ch...

Jaclyn Dang 3B

The bonds get shorter due to the fact that they are pulled in closer. Double bonds have more electrons and are pulled in more tightly. Using this, you would know that triple bonds are shorter than double bonds and double bonds are shorter than single bonds.

Jaclyn Dang 3B

Filling the d sub orbitals first gives it a lower energy level. And electrons want to be in the lowest energy state because that is when they are most stable, therefore they fill those sub orbitals before the s.

Jaclyn Dang 3B

You can also check your progress via MyUCLA. I saw today that I have 20/50 points which is what I should have since i posted 5 times a week for 4 weeks. Hope this helps :)

Jaclyn Dang 3B

Sides does not matter as long as you have the correct number of electrons. I always try to make the lewis structure as symmetrical as possible

Jaclyn Dang 3B

I dont want to repeat what is said above, so I wanted to add onto information about formal charge, the formal charge of each atom should add up to the total charge of the molecule

Jaclyn Dang 3B

I keep it in m since velocity is m/s. Hope this answers your question

Jaclyn Dang 3B

Will there be more modules with the pre and post assessments like the ones for Outline 1 and Outline 2? I found these super helpful!

Jaclyn Dang 3B

Hi all, I know course enrollments are coming up, so I wanted to see if anybody knows how the structure of chem 14BL has changed due to remote learning?

Jaclyn Dang 3B

Will we be able to see midterm 1 scores right after we take the midterm or do the scores wait until all students have taken the exam?

Jaclyn Dang 3B

There will be no orbitals and little Schrondingers. Maybe some basic questions on quantum numbers

Jaclyn Dang 3B

Thank you for the responses! I was reading ahead and had this question and didn't realize that the professor answered in lecture already!

Jaclyn Dang 3B

Does anybody know if the midterm is free response or multiple choice? Also how many questions?

Jaclyn Dang 3B

I take notes,read the textbook, watch lectures and practice the textbook problems from the outline. I am going back and doing the modules again to make sure I understand it.

Jaclyn Dang 3B

How do we know if something has measurable wavelength properties? How do we know if we can detect it or not?

Jaclyn Dang 3B

Hi, I'm not sure where to start on this problem, if anybody can give me the steps along with a quick reasoning/explanation, it'd be highly appreciated! As you may well know, placing metal objects inside a microwave oven can generate sparks. Two of your friends are arguing over the cause of the spark...

Jaclyn Dang 3B

Hi, I'm not sure where to start on this problem, if anybody can give me the steps along with a quick reasoning/explanation, it'd be highly appreciated! A blue line is observed at 486.1 nm in the spectrum of atomic hydrogen. Determine the values of n for the beginning and ending energy levels of the ...

Jaclyn Dang 3B

Can anyone tell me what I am doing wrong in this problem? I keep trying it but it comes up as incorrect A liquid is exposed to infrared radiation with a wavelength of 5.56x10^-4 cm. Assume that all the radiation is absorbed and converted to heat. How many photons are required for the liquid to absor...

Jaclyn Dang 3B

How do you guys keep track of how many posts you've done? In the early weeks its easy but any tips for keeping up with them later on?

Jaclyn Dang 3B

I remember the professor saying that equations and the periodic table will be given to us! I'm pretty sure he will go more in depth as the midterm creeps up on us.

Jaclyn Dang 3B

My TA didn't say anything about quizzes, is this for all sessions?

Jaclyn Dang 3B

Are step up sessions or workshop sessions better for understanding material that may be on exams? Can I still attend workshop sessions if I don't have a strong background in chemistry?

Jaclyn Dang 3B

As stated before, reading the textbook is not required, but may help develop an indepth understanding of the topics. If you dont want to read the book I would recommend skimming it or referring back to it if you get confused!
