I never do work on Fridays. I reserve that day for me and my needs. whether that's giving myself a pedicure or eating some good food and watching a movie. You are just as important as school and work and whatever else you're doing. Don't feel bad for doing things that make you happy!

LeahSWM 2E

Burnt out completely but so so happy that spring break is here. Kind of getting war flashbacks of having to leave campus around this time but happy that I made it through. Very Blessed, Remember to count your blessings!

LeahSWM 2E

Sapling is good for quick review and viewing the solutions and seeing how problems are done and reading conceptual stuff. It helped me a lot.

LeahSWM 2E

Love this thread! was just saying I wanted to read more books my phone is getting annoying lol. Definitely read Becoming by Michelle Obama!

LeahSWM 2E

I plan on moving to an apartment by the school! super excited. Not for the rent tho lol.

LeahSWM 2E

only 14b

LeahSWM 2E

I love burgers and fries and strawberry lemonade. And occasionally some bomb Mexican Food!

LeahSWM 2E

A wise woman once told me to only worry about something 30 minutes before a big event, and then after literally forget about it lol. So that's what I do, I worried enough already so honestly what happens, happens.

LeahSWM 2E

I'm definitely a visual learner so writing out my notes definitely helps me retain info. Typed notes are cool as well but writing has worked for me thus far so I stick to it.

LeahSWM 2E

I'm sure they'll try and give students the option but honestly I hate remote learning. I miss interacting and getting that in person connection. College is more than schoolwork in my opinion its about the experience as well.

LeahSWM 2E

Summer I'll be taking 14C and CL and physics and then hopefully end of summer I'll get to take a trip or two!

LeahSWM 2E

unfortunately no! another professor teaches 14C :(

LeahSWM 2E

Thank You Dr. Lavelle ! you're an amazing professor.

LeahSWM 2E

I thought the final was fair and the questions were very straight forward! Not too sure how well I did but definitely felt more confident than last quarter's final.

LeahSWM 2E

Them Yellow Redbulls from 7-eleven come clutch! lol honestly if you can go ham for today and Saturday, reviewing textbook problems, taking short breaks, and looking over some crash courses on YouTube, you can totally do it. I am in the same boat and honestly having a job can either kill you or make ...

LeahSWM 2E

currently just doing things that make me happy, and revisiting the reasons I'm even in school. I take a hike once a week now, and allow myself the adequate time to be present and or to just lay and do nothing. All this has been really hard to handle so remember to not take life too seriously but kno...

LeahSWM 2E

I literally need a crash course for every topic in this class lol

LeahSWM 2E

I believe Sunday night before midnight!

LeahSWM 2E

Winter Quarter is brutal but we fighting back! lol proud of us foreal!

LeahSWM 2E

If you like alternative R&B, I definitely suggest lucky Daye's album Painted. Such a good album I love studying to it!

LeahSWM 2E

New Girl is freaking hilarious if you need a good laugh. I'm gonna be so sad when I finish *crying emoji*

LeahSWM 2E

I miss the campus so much! I truly miss walking to class strangely enough, I miss the hustle, going to the hill to eat after classes, going to relax on the grass next to BruinWalk :( this time is really sad but it makes you appreciate the small things you can take for granted.

LeahSWM 2E

I think chem community is still available for us to view, just can't make comments!

LeahSWM 2E

I believe they will always provide that information, so you're good!

LeahSWM 2E

k is only affected by change in temperature!

LeahSWM 2E

E naught is basically E but in standard conditions, so think Celsius, Kelvin, atm, etc...

LeahSWM 2E

A compound can be oxidized and reduced in the same reaction, but not necessarily at the same time.

LeahSWM 2E

Definitely Kinetics and Chemical Equilibrium!

LeahSWM 2E

I'm apart of the BPHO (Black Pre-Health Organization)! Great resources and connections!

LeahSWM 2E

I'm taking Chem BL next quarter, and then 14c and CL in the summer.

LeahSWM 2E

I'm taking it this spring quarter as well! I didn't want to overwhelm myself considering the times.

LeahSWM 2E

One Tree Hill on Hulu! very addicted lol

LeahSWM 2E

I don't watch football hehe. Travis Kelce is cute tho, so whatever team he was on lol.

LeahSWM 2E

Yes, make sure to match the units always.

LeahSWM 2E

Cv + R = Cp // I was stuck so bad on this during the sapling homework, but you basically subtract an R from Cv to get the Cp.

LeahSWM 2E

The final is the only cumulative test!

LeahSWM 2E

Finding Nemo :) it makes me feel safe.

LeahSWM 2E

Yes, isolated systems equal 0 because they do not transfer energy.

LeahSWM 2E

ICE box is used to find an unknown concentration.

LeahSWM 2E

always go with the positive when presented with a negative and a positive. if both are positive you'll have to use both in further steps and see which one gives you a negative value.

LeahSWM 2E

To get the percent ionization, you would divide the concentration of H+ equilibrium by the initial concentration of the acid, and then multiply that value by 100 to get your answer!

LeahSWM 2E

It depends whether it is a reactant (-x) or product (+x).

LeahSWM 2E

You would only include H2O if it is in a aqueous phase, not when it is in the liquid phase.

LeahSWM 2E

Sometimes you have to use a lot of parentheses in order for it to work. I got fed up and just used a quadratic formula calculator online and saved me the time and trouble.

LeahSWM 2E

currently in love with Eric Bellinger and Victoria Monet! can't go wrong with a little Meg the Stallion as well!

LeahSWM 2E

Did you hear about the chemistry joke that flopped?

It got no reaction.

LeahSWM 2E

I remember hearing they'll be proctored during scheduled lecture time on Fridays!

LeahSWM 2E

H2O is only included when it is in a gaseous phase!

LeahSWM 2E

Yes, K is used when the equation is at equilibrium while Q is when it is not.

LeahSWM 2E

When you reverse the reaction of K, the value becomes 1/K.

LeahSWM 2E

Water is amphoteric, which means it can act as both an acid and a base.

LeahSWM 2E

I guessed on like that the last 15 questions. It was a really sad time for me :/. We live and we learn though!

LeahSWM 2E

Since 50% is a C- in this class, anything above it is a passing grade!

LeahSWM 2E

As this very... interesting year comes to an end, has anyone put any thought into what they want to achieve for the next year, whether it is academically, personally, etc? For example, I definitely want to really develop my study habits, but also take more time to journal and reflect on life to furt...

LeahSWM 2E

I'm just excited to eat good food, watch Christmas movies, spend time with family, and start working on my new year's resolutions. Keeping that in mind I am working hard to finish this quarter strong so I can fully enjoy this little break we have! wishing the best to you!

LeahSWM 2E

I missed out on like 20 minutes of my exam because I had to get my materials checked before I could start :/ that was a bummer but there's nothing to do now except to move forward.

LeahSWM 2E

They are usually always updated on myUCLA under chem 14A grades. the 17th (tomorrow) at 8 am is the last day to post!

LeahSWM 2E

You are at the number 1 public university! You are more than capable of everything you wish to achieve!

LeahSWM 2E

I really need to start studying the week I learn the material! that has been my biggest lesson overall. Cramming simply only works for moderate material, it does NOT work for chemistry! there was always a topic I was left shaky on and that ended up affecting my grades on the midterm. We live and we ...

LeahSWM 2E

currently in need of a self-care day! And a vacation in the bahamas! but a nap will do just fine.

LeahSWM 2E

A HUGE thank you to all the UA's and TAs who hosted review sessions for us. Helped me so much and I am so grateful!

LeahSWM 2E

I wish there was a way to check our grade instead of having to calculate it ourselves, I don't always trust my own math lol.

LeahSWM 2E

Final grades will be up on Saturday, according to Dr. Lavelle's email!

LeahSWM 2E

no partial credit, unfortunately. Dr. Lavelle did say something about 10 extra points being applied!

LeahSWM 2E

You're fine! most of the time they're usually worth extra credit so it won't affect anything. I did not fill out any last year and nothing happened lol.

LeahSWM 2E

Leave it in scientific notation, it'll give the same answer!

LeahSWM 2E

This quarter truly tested me as a student, mainly because I felt really alone without the social aspect of college. Then my best friend facetimed me and offered to just sit on the phone with me while I studied and did assignments and that helped tremendously! If you have a friend who is struggling, ...

LeahSWM 2E

bent and angular are actually interchangeable!

LeahSWM 2E

After finals, I am hosting a self-care day... All my favorite foods, face masks, a mani and Pedi, and lots of Christmas movies. Be kind to yourself you deserve it!

LeahSWM 2E

I will simply just be forgetting. lol. will not catch me doing any studying until January 5th.

LeahSWM 2E

I feel like the first class of a series is meant to show you exactly how to study the material and how much time to devote to it. Chemistry requires a lot of practice! Moving forward, I will attempt to work through textbook problems the week of learning them so when it is time to study for midterms ...

LeahSWM 2E

This Winter break I will be ccatching up on all the holiday spirit I pushed back to study and be present with school. Finally going to put up some decorations and watch my holiday movies and spend time with the fam! Oh yeah, and sleep for 3 days straight lol.

LeahSWM 2E

Lo-Fi playlists are great, and strangely baby lullabies work good for me too! lol they keep me calm and reduce my anxiety.

LeahSWM 2E

Hi! Zinc ion is usually 2+ charged because its electron configuration is [Ar]3d 10 4s 2 , so it readily loses 2 valence electrons in 4s-orbital, similar to Group 2 metals. Then, since hydroxide ion and nitrite ion are both 1- charged, the "zinc:anion" ratio is 1:2. This gives you Zn(OH) 2...

LeahSWM 2E

Yes, just like with the midterms with a few more questions.

LeahSWM 2E

yup, you arrange it by the ligand name without the prefix.

LeahSWM 2E

Jason Knight - 1D wrote:Polyprotic acids are defined as acids that are capable of losing more than one proton per molecule in acid-base reactions. An example would be (H2CO3) which contains two acidic protons capable of ionizing two H+ atoms per molecule.

thank you for this clarification!

LeahSWM 2E

Shana Patel 1C wrote:pH of 8.85
[H+] = 10^(-8.85)
pOH = 14 - 8.85 = 5.15
[OH-] = 10^(-5.15)

this is a great breakdown, thank you!

LeahSWM 2E

Organic Chemistry tutor is the goat! really helps clear up topics you're still shaky on. Also going over past finals if you can find some online and working through the problems is cool too. You can even time yourself and make it feel like a real exam.

LeahSWM 2E

supposedly we're all going to be split up into different groups, and half of our usual discussion will be with a different TA. Something to that effect lol. We should get a clarification email soon!

LeahSWM 2E

Thank you for this! I am trying to put my best foot forward considering how hard things were for me this quarter. Best of luck to everyone reading this... you are beyond capable!

LeahSWM 2E

Weeks 8 and 9 always feel so stressful because there's this pressure to go extra hard with studying for the final. I, unfortunately, have tapped out of this quarter so whatever I don't know, I truly just don't know. I'll always try to put in the work, but I am done stressing myself out honestly.

LeahSWM 2E

Thank you for clearing this up!

LeahSWM 2E

Hellooooo,

mmol stands for millimole. 1 mmole equals 0.01 mole.

LeahSWM 2E

I definitely have been thinking of changing my major. I am currently a Gender Studies major, but I'm also pre-med. For me, I enjoy Gender studies so much and my plan was to be original for medical school and stray away from a common science major, but I am afraid that it is not a workable major for ...

LeahSWM 2E

Honestly, overwhelmed. On top of UCLA classes, I am working a job that I go to right after I finish my classes. I close almost everyday, so I come home at 10:30. I just always feel like I have absolutely no time for anything, and December is one of those months that keep me up all night. Scared for...

LeahSWM 2E

Hello! A dipole moment is a measure of the polarity of a certain bond. Therefore, if we have a polar bond, then it will have a non-zero dipole moment. Of course, a polar bond arises from the unequal sharing of electrons between atoms (differences in electronegativity), so a dipole moment is also a ...

LeahSWM 2E

You are smart and beyond capable! You got this!

LeahSWM 2E

I didn't do as great as I wanted on my midterm :( I have faith in this second one though I feel I've found the right resources to study with!

LeahSWM 2E

School is stressful and hard at times! Most students at this university put their 110% and leave little time for themselves. But please, if you put in the hours, take some time for yourself and do the things that make you happy or bring you peace. Don't overcrowd your brain, everything that you need...

LeahSWM 2E

I heard Organic Chem on youtube is super helpful, I watch from time to time for a few topics! Also, khan academy is a life saver. Textbook problems are definitely the best way to go for studying though.

LeahSWM 2E

From what I read, the electronegativity difference has to be between 0.5 and 1.6 to be considered polar. Anything less than 0.5 is non-polar!

LeahSWM 2E

A partial charge is indicated by which atom of a bond has the higher EN and which has the lower EN. A formal charge is indicated by the # gained or lossed electrons.

LeahSWM 2E

James Patanian 2C wrote:Another thing is when drawing the structure of a compound, the most electronegative atom(s) (or highest ionization energy) is the one in the middle of the other atoms.

This cleared things up for me! Thank you!

LeahSWM 2E

On the periodic table, electronegativity increases from bottom to top in groups, and increases from left to right across periods!

LeahSWM 2E

The textbook is very confusing for me; I find it difficult to process any information. Any tips? good alternatives?

LeahSWM 2E

How exactly are we supposed to receive credit for our work if it is multiple choice?

LeahSWM 2E

Take advantage of PLF sessions for this class! Don't know what I would do without it!

LeahSWM 2E

Having a hard time getting accurate answers that my peers are getting. Any tips? should I be doing something special?

LeahSWM 2E

If you feel you have studied your best, there's no need to overthink it. Meditate, eat a good breakfast, and remember you're more than capable!
