I plan on working this summer and saving up for living expenses for next year:) I’m also taking summer courses, and hopefully I can visit some family up north in late July hehe

Maryeli Garay 2H

I think Dr. Lavelle only teaches the first two courses in the chem 14 series :(

Maryeli Garay 2H

Thank you Dr. LL! It was a good quarter I hope everyone finished off strong :)

Maryeli Garay 2H

I think they should be out by this weekend or early next week! Lavelle will probably send out an email when they’re posted :)

Maryeli Garay 2H

I honestly have just decided to forget it ever happened, I’m currently binge watching OITNB for the third time before I continue with finals tmrw:( So I would say just try to watch a comfort movie or spend time with your friends to take your mind off things

Maryeli Garay 2H

Adding a catalyst results in a decrease in activation energy in a reaction, which means that it goes faster! This is true for the reverse reaction too, so it goes faster as well :)

Maryeli Garay 2H

I’m taking 14C next quarter, I wanted to take 14BL too but it’s full :( so hopefully in the summer I can take it

Maryeli Garay 2H

I think 14C is more similar to 14A than 14B, but I would keep any notes regardless because they will probably be useful for any exams or even just to help someone else :)

Maryeli Garay 2H

Thank you for a great quarter Dr. Lavelle! Hope everyone has a good spring break :)

Maryeli Garay 2H

I think they’ll probably be out by next week at the latest, maybe early on in the week.

Maryeli Garay 2H

Mine does that too, usually refreshing the page fixes it, or logging out and logging back into the assignment thru the CCLE link :)

Maryeli Garay 2H

I'm pretty sure we don't need to memorize them all, but I feel like it would help to know the most common ones :)

Maryeli Garay 2H

I honestly did better on this second midterm than I thought I would, so I'm glad but I'm definitely not looking forward to taking the final LOL

Maryeli Garay 2H

Hi, here are some of my Spotify Playlists if y'all wanna check them out :) Spanish music (Reggaeton, banda, cumbia, idk) : https://open.spotify.com/playlist/4Axsr1nRPCedWbYFRScZdB?si=5h3HYS0IREKJA2b_R-wjHQ rap/trap/hip-hop (explicit fasho) : https://open.spotify.com/playlist/3RbmqhIV5tsau2W4kQNi0z?s...

Maryeli Garay 2H

Hi! I've been involved in MEChA, ucla pre-dental society, hermanas unidas and CityLab :)

Maryeli Garay 2H

I have a part time job in food service, and it can honestly be a lot sometimes. I feel super overwhelmed when I have a lot of work and school work too, but I guess the most important thing is communication with your manager about your needs and time off! :)

Maryeli Garay 2H

I think it's usually a week after we take the exam! So hopefully this Thursday or Friday :)

Maryeli Garay 2H

Congrats y'all! It was honestly terrible, but I've just been trying to forget about it this whole weekend LOL

Maryeli Garay 2H

Hi! I'm not in this class or discussion, but I would suggest asking in the class groupme! There are a lot of people in it and I'm sure someone there will be able to switch :)

Maryeli Garay 2H

I love boba! I usually get mango green tea or match & strawberry :) It's my go-to snack when I'm with friends lol

Maryeli Garay 2H

jeffrey van 2I wrote:So just to clarify, spontaneous means that it goes from higher energy to lower energy?

Yes I think so! the system moves to a lower energy state and releases free energy :)

Maryeli Garay 2H

Yes I'm pretty sure the remaining exams will be proctored in the same way with the same TA over Zoom :)

Maryeli Garay 2H

I think UA sessions really help! And also just Youtube videos on specific topics :)

Maryeli Garay 2H

Yes the equation will likely appear on the exam! it is in the thermodynamics outline, i think outline 4 :)

Maryeli Garay 2H

Omg thanks for this I hate taking exams, they make me so anxious. We need to remember that our grades don't define us! And a bad score isn't the end of the world :)

Maryeli Garay 2H

I like sort of sci-fi, fictional books because they're more fun to read than non-fiction to me. So I would recommend the "Uglies" series, the Divide trilogy, or honestly even the twilight books LOL I actually liked them when I was younger :)

Maryeli Garay 2H

After this week (week 5) I think it should be out of 25. Also, I think that as long as you have 50 posts by the end of the quarter (week 10) you should be good :)

Maryeli Garay 2H

I was wondering this too because I was stuck on #18 on Sapling for the longest time. But from what people have said on the groupme, it seems like Cv + R = Cp or like Cv - Cp = R.

Maryeli Garay 2H

I'm pretty sure Midterm 2 is just everything from the first exam up till now. The final will be cumulative though :)

Maryeli Garay 2H

I just finished the vampire diaries and I actually almost cried. But I just finished The queen's gambit and it was sooo good! Everyone should definitely watch it :)

Maryeli Garay 2H

I don't think they've mentioned it yet, but I'm sure they will more than likely tell us this week since our midterm is the 19th :)

Maryeli Garay 2H

I'm here after the game, but I was rooting for the bucks! So I'm glad they won; I'm not even a big football fan, but I was pretty invested lol. Also the Weeknd did pretty good

Maryeli Garay 2H

I think I'm gonna take 14BL in the summer, just because I know it's a lot of work and I'm gonna be pretty busy during spring quarter :(

Maryeli Garay 2H

yes, you can attend any of the office hours to review your exam, I don't think it has to be your specific TA

Maryeli Garay 2H

I would suggest using an online quadratic calculator to check your homework answers, but for sure be comfortable using a handheld calculator to solve problems like these because that's what we can use on the exams! :)

Maryeli Garay 2H

Hess's Law states that the change in enthalpy in a chemical reaction is a fixed quantity and it's independent of the steps in the reaction

Maryeli Garay 2H

I think Dr. Lavelle posted them on his website and he updates them too, under where is says "Peer Learning Sessions and Step-up program" :)

Maryeli Garay 2H

I'm sure we will be using it quite a few times on the exam, like for conversions between molarity and pressure.

Maryeli Garay 2H

pKa is the -log of Ka, like what we did in some of the homework problems from week 2. pKa tells you how strong an acid may be

Maryeli Garay 2H

I think they're pretty equal in value so they can be used interchangeably for solving problems :)

Maryeli Garay 2H

I find youtube videos helpful when I'm not too sure on a problem, since they usually include simplified explanations and examples!

Maryeli Garay 2H

I think the exams are going to be during lecture this quarter instead of during our discussions, I'm not 100% sure though

Maryeli Garay 2H

I think both graphing and scientific calculators are allowed for the exams :)

Maryeli Garay 2H

The first midterm is on January 29th. I think it's during lecture this quarter instead of during discussions.

Maryeli Garay 2H

If you bought the package for last quarter it should give you the option to use credit for this course. If you have trouble I’d recommend contacting the ucla store!

Maryeli Garay 2H

The Sapling problems that are assigned every week are mandatory. The first set is due at the end of week 2, not tonight! :)

Maryeli Garay 2H

Yes you can get credit from that. You can post your own topics/Questions or just reply to other people’s posts. As long as you have 5 posts by the end of the week you’re good!

Maryeli Garay 2H

Bars and atm can be used i think!

Maryeli Garay 2H

I think going over homework problems and textbook problems is really helpful! Just to review and see a lot of examples on certain topics. Also asking questions during discussion or UA sessions.

Maryeli Garay 2H

Some classes give extra credit for filling them out, but theyre not mandatory

Maryeli Garay 2H

Yeah I felt more rushed for the final than I did for the previous exams :(

Maryeli Garay 2H

miguel zatarain 2B wrote:hey. Im just gonna sleep all break and wake up until the first (maybe second) day of class

hey lol. that sounds so scrumptious to me, I think I will do the same. except I will simply not wake up again, ever

Maryeli Garay 2H

If you're already in the 14A groupchat I don't think you need to worry about joining a new one, I'm pretty sure it just shifted to a 14B chat lol

Maryeli Garay 2H

Unfortunately I don't think partial credit is given for the final exam :(

Maryeli Garay 2H

Next quarter I definitely plan on going to more UA sessions and just doing things earlier overall. I feel like I was rushing through everything this quarter, and that's definitely something I want to change.

Maryeli Garay 2H

I am literally losing my mind. I’m so over this quarter, I can’t wait for winter break!! I just think we’re all tired and dealing with so many things apart from school. We could all use a little break :(

Maryeli Garay 2H

I’m pretty sure Lavelle isn’t offering extra credit for completing the evals. But I would check with you other classes just to see if you can get EC in those courses :) anything helps lol

Maryeli Garay 2H

I plan on spending time with family and watching the office on Netflix before it’s removed on December 31st!:(

Maryeli Garay 2H

Going through the textbook problems for extra practice is probably gonna be very helpful. Also, someone here on chem community posted some review sessions that some students had over Zoom, so I’m gonna be looking into that as well!

Maryeli Garay 2H

Thank you!! Honestly this is super helpful, I’m sure everyone who uses this will be super grateful!! :’)

Maryeli Garay 2H

I would say textbook problems and UA sessions are the most helpful!

Maryeli Garay 2H

Yes :) because both digits are in front of the decimal

Maryeli Garay 2H

Most people have said that textbook problems are a big help when studying for exams, so I would for sure go with that. Also, watching review videos on YouTube always helps too :)

Maryeli Garay 2H

I don’t think we have to know exact bond angles, I think we just need to be able to decipher if a given angle is bigger or smaller than those around it or compared to another molecule.

Maryeli Garay 2H

If you want to tell by just looking at a structure I’d say look for symmetry. Nonpolar molecules are symmetric and polar molecules are asymmetric.

Maryeli Garay 2H

I’m pretty sure it’ll be covering everything from weeks 1-10 :( And for those wondering, I’m sure it’ll be MC too, like exams 1 & 2

Maryeli Garay 2H

I feel the same way :( I think we just have to try our best moving forward, we still have some time to get points!! Good luck, you got this!!

Maryeli Garay 2H

He will probably post a lecture on Friday, but I think discussion sections will be cancelled for Thurs & Friday, I’m not 100% sure though.

Maryeli Garay 2H

They’ll probably be posted sometime this week, I’m thinking either Wednesday or Thursday:)

Maryeli Garay 2H

The Organic Chemistry Tutor has some good YouTube videos!! And like everyone else said, Khan academy for sure :)

Maryeli Garay 2H

Good luck everyone!! Let’s try our best, and don’t forget to get some rest along the way too!

Maryeli Garay 2H

We’ll have the same amount of time for the exam, but I’m sure it’ll be enough to finish, since the questions will likely be shorter / less time consuming.

Maryeli Garay 2H

In order to be polar I believe the electronegativity needs to be between the 0.5 and 1.6 threshold. If it’s over this threshold it is ionic :~)

Maryeli Garay 2H

I think that for the upcoming midterm we’ll be given the equations and all that so it’s not necessary to memorize them :)

Maryeli Garay 2H

I’m pretty sure we’re not gonna need to know how to solve for/calculate the bond length for the upcoming midterm!

Maryeli Garay 2H

Hydrogen is a smaller atom than oxygen, so the bond between H and N is gonna be shorter. :)

Maryeli Garay 2H

I’m pretty sure Sapling weeks 5-6 is due next Sunday night :) hopefully lol

Maryeli Garay 2H

I would follow green if they sus, because if I go missing and Green comes back alone, the rest of the crew will know they are the imposter :~)

Maryeli Garay 2H

I’m not sure on the question count, but if it’s the same amount of points, I would say it’s around the same # of questions :) If anything, there might be more questions but worth less points each, or less questions but worth more points each. I think it’ll still be out of 110 points.

Maryeli Garay 2H

I’m definitely nottt doing well :) I hate school, and the online format makes it harder. I honestly just want this quarter to be over lol.

Maryeli Garay 2H

I think he said that higher point questions have chances for partial credit but I'm also not completely sure how it works.

Maryeli Garay 2H

Mine doesn't do this but it has been signing me out randomly and pretty often, I don't know maybe Sapling is having issues with everyone on it at the same time lol

Maryeli Garay 2H

I watched a scary movie with my bestie Miguel! We had so much candy and just chilled because #pandemic :(

Maryeli Garay 2H

I think attending UA workshops really helps!

Maryeli Garay 2H

Thank you sm!! I got it :))

Maryeli Garay 2H

Hi guys, can anyone help me with this question? The electron in a hydrogen atom is excited to the n=5 shell and emits electromagnetic radiation when returning to lower energy levels. Determine the number of spectral lines that could appear when this electron returns to the lower energy levels, as we...

Maryeli Garay 2H

A lot of people were saying that using your phone is okay! You just need to connect to Zoom on your phone as well as on your computer.

Maryeli Garay 2H

To my understanding, both fundamentals and the quantum world will be on this midterm. The midterm covers material from weeks 1-3! :)

Maryeli Garay 2H

The Hydrogen has to bond with F N or O, because they are more electronegative than H.

Maryeli Garay 2H

I wouldn't worry about that, like most people said, the answer choices would be very distinct- if there even are any questions on sig figs in the first place :)

Maryeli Garay 2H

I love to light a candle, turn my sky lights on and just watch Netflix in bed. :) It's important to unwind and make time for yourself, especially right now with everything going on! Everyone deserves some me time.

Maryeli Garay 2H

From what I’ve heard they have prepared content for that week/current topic, but I would say going to office hours would be your best bet! Also you can always post your question on the groupme and people usually answer questions fairly quickly :)

Maryeli Garay 2H

There should be a link on CCLE! I already have it downloaded on my laptop from a previous class, and I would just advise you to make sure you have it all set up before the midterm, because you need to have a camera check/microphone check, etc.

Maryeli Garay 2H

Hi! I don’t know if you’ve already seen Lavelle’s most recent email but he clarified that the homework on Sapling is now updated. It covers weeks 2-4, and the deadline to submit/complete it is midnight on Sunday week 4!

Maryeli Garay 2H

I would say going over practice problems from the book would be most beneficial, as well as attending any step-up sessions from here until the midterm. I also think joining/making study groups would help because you can get someone else’s perspective on questions, or teach concepts to others which i...

Maryeli Garay 2H

Hi, personally I don't think it is as helpful to know the names of the equations as it is to know how they work and when to use them. Of course knowing the names is a plus, but I wouldn't worry too much about knowing them off the top of your head, since they'll probably be given to us for the exams....

Maryeli Garay 2H

You would want to first count up all the atoms of each element, in order to get the molecular formula. Once you have this, you can find the molecular mass by looking up the elements on the periodic table. You find each of their atomic masses, then multiply this with how many atoms of the element the...

Maryeli Garay 2H

Thank you Dr. Lavelle! This is the first chemistry class I have taken at UCLA, and your help has made me feel more comfortable in the course. I appreciate all the resources you have worked so hard to make available to us, a lot of professors wouldn't do the same. I can tell you really want your stud...

Maryeli Garay 2H

I like to just take a look at the reactant side (left) first, and count the number of atoms in the molecules. Then, I look at the products (right) and make sure the # of atoms is the same. If not, then you can get to balancing. I go ahead and add coefficients onto the molecules that need them, and t...

Maryeli Garay 2H

When you balance chemical equations, it is better if there are no fractions as coefficients. You can go ahead and multiply all the other coefficients in the equation by the denominator, to make it a whole number.
