Charisma Arreola 2F

Ive been playing Best Friend on repeat, along with Mr. Brightside!!

Charisma Arreola 2F

I like to remind myself why I started in the first place and go over my goals.

Charisma Arreola 2F

I recommend the Harry Potter series as comfort books!

Charisma Arreola 2F

I’m really sorry to hear. It’s hard to stay positive when life seems to tear us down but find strength within and you’ll always come out of it.

Charisma Arreola 2F

I use my iPad so I use goodnotes which is really helpful at organizing!

Charisma Arreola 2F

I plan on taking a few classes but in between I definitely will be going to the beach to relax.

Charisma Arreola 2F

If it is technology like a cell phone it’ll go off at the new 8am!

Charisma Arreola 2F

I think it’s because of the difference and how small pKa values typically are.

Charisma Arreola 2F

I would say just remember that you did your best and that’s all you could’ve done.

Charisma Arreola 2F

I would talk to your counselor about retaking any classes and if it is even worth it as a freshman.

Charisma Arreola 2F

I do not think he does but he does have bonus questions on the final.

Charisma Arreola 2F

Lately i’ve enjoyed anything caramel flavored.

Charisma Arreola 2F

There’s a few he has mentioned so I would recommend looking over those.

Charisma Arreola 2F

Remember everyone that a grade does not define you!!

Charisma Arreola 2F

I am pretty sure all calculators are allowed!

Charisma Arreola 2F

Only 14B! But if you want to be sure you can check the outlines.

Charisma Arreola 2F

I think I will be!! Learning at home has been difficult so I do want to go if possible.

Charisma Arreola 2F

WandaVision is one of the best, too bad it comes out every Friday

Charisma Arreola 2F

We did! And it went better than midterm 1 as well.

Charisma Arreola 2F

I am pretty sure you just need 50 by the end of the quarter to get full credit.

Charisma Arreola 2F

Both the grades tab on CCLE and MyUCLA!

Charisma Arreola 2F

Hope everyone had a great Valentine’s Day!!

Charisma Arreola 2F

Italian food, specifically pastas are my ultimate go-to!

Charisma Arreola 2F

I recommend that you set intervals for studying and in between those intervals you do something to relax!

Charisma Arreola 2F

Dr. Lavelle,

Thank you for all the extra work you have put in for us to understand chemistry. You have provided generous opportunities for growth.

Charisma Arreola 2F

No, although it is similar.

Charisma Arreola 2F

When oxygen isn’t balanced, water needs to be added.

Charisma Arreola 2F

An exothermic reaction has energy escaping, whereas endothermic takes in energy and heat.

Charisma Arreola 2F

If you need help with specific problems, the step ups are probably better. Workshops are more similar to discussions and office hours.

Charisma Arreola 2F

Definitely the chiefs. Ill even make a prediction of 21-37.

Charisma Arreola 2F

Hey so this is totally normal and it is easy to feel overwhelmed in a situation like this. But remind yourself that a grade doesn’t define you first of all. Also, take breaks when needed. Then remind yourself why you chose this school and major and remind yourself of what you’re working towards. The...

Charisma Arreola 2F

Vapor and water are the same phase.

Charisma Arreola 2F

External pressure is an outside pressure pushing down.

Charisma Arreola 2F

A phase change is when the substance either releases or takes in heat to go between a solid, liquid, or gas.

Charisma Arreola 2F

Honestly watching the lectures after reading the textbook, then going back to do the textbook problems is really helpful.

Charisma Arreola 2F

Q denotes heat and H is enthalpy.

Charisma Arreola 2F

I really enjoy And Then There Were None, because it gets your brain going!!

Charisma Arreola 2F

Michael Nguyen is really good with reviews!

Charisma Arreola 2F

It is an isolated system!

Charisma Arreola 2F

A great refresher would be the audio visuals posted on Dr. Lavelle’s website, because they cover the basics and can help you get reintroduced into the chapter.

Charisma Arreola 2F

They are really helpful to start out with! I think the best thing to do is to watch them beforehand.

Charisma Arreola 2F

Any calculator should be fine but I recommend double checking with your TA as well.

Charisma Arreola 2F

Review textbook problems, summarize notes from lecture, and attend workshops from different TAs!

Charisma Arreola 2F

I highly recommend doing the textbook problems from the outline, as well as attending workshops.

Charisma Arreola 2F

If the concentration increases that is a positive x, but if it decreases then it is a -x.

Charisma Arreola 2F

Whichever x value is smaller than the initial concentration is the one you will use.

Charisma Arreola 2F

I highly doubt we will be tested on those since there has been a lack of problems like that on sapling.

Charisma Arreola 2F

My comfort movie would probably be either She’s All That, the entire Harry Potter Series, or Someone Great. I know these are different in many ways but they all feel comforting when I am stressed or upset.

Charisma Arreola 2F

The shift indicates which side is favored (product or reactants).

Charisma Arreola 2F

You’ll first use the original amounts to find the equilibrium constant, then set up an ICE table to solve for x with the added concentration. From there you will find the new equilibrium constant.

Charisma Arreola 2F

The inverse is used when you have a reaction with the correct compounds but the reactant or product is on the wrong side.

Charisma Arreola 2F

The e textbook will take the least amount of time to access so I recommend getting that one.

Charisma Arreola 2F

If you want to directly go to Chem 14B, you could always search up that in the top right or quick links area.

Charisma Arreola 2F

I highly doubt it will be covered on the test.

Charisma Arreola 2F

If it happens again, try using the VPN so that there is less trouble playing them!

Charisma Arreola 2F

Good luck to all! And do not forget that a grade does not define you.

Charisma Arreola 2F

Yes, it will be almost exactly like our past midterms!

Charisma Arreola 2F

The best way for me is to rewrite the notes in either a more simplified, or less confusing way so that I make sure I understand what I am writing down, and its in my own words. Also, recognizing which topics are my weaknesses allows me to work on those more. I think everyone is different, but these ...

Charisma Arreola 2F

There will most likely be a fair amount from the textbook, even more from the topics that we covered the longest.

Charisma Arreola 2F

Yes, we should know the most common and most strong acids and bases. This way you can better figure out the strength of other acids and bases.

Charisma Arreola 2F

I heard somewhere that it is cumulative, but that there will be a focus in the quantum world because that was a big topic for us.

Charisma Arreola 2F

Remember that a grade does not define you, and take a breather. Stop thinking about the class for a bit, and instead do something that makes you happy. Then come back, study, and feel better about everything that is going on.

Charisma Arreola 2F

Watching YouTube videos and going to TA review sessions are really helpful in reviewing for the class!

Charisma Arreola 2F

I believe the majority of questions will come from the textbook problems!

Charisma Arreola 2F

Since there aren’t too many, make flash cards and memorize them! I’m sure you’ll feel better if you do.

Charisma Arreola 2F

I do not think there is, but I would say that practicing homework problems from the textbook is the best way to review!

Charisma Arreola 2F

Thank you all!!

Charisma Arreola 2F

Hi! I also got a much, much lower score on this midterm compared to midterm 1. I recommend not overstressing, and instead focus on what you can do like studying for the final. A 50% is needed to pass, which is 250/500 points total for this class. Try to set a realistic goal for the final and keep pu...

Charisma Arreola 2F

Honestly I did not do so well on midterm 2 compared to midterm 1, so I will be reviewing those topics twice as much as the topics from midterm 1. I say strengthen what you already know, but create flash cards and do practice problems for topics that are a little more troubling. Also, there are a lot...

Charisma Arreola 2F

I solved for number 15, but can someone better explain the reasoning for pi bonds in a molecule and how they determine the shaping. I still do not understand the correlation. Thank you!

Charisma Arreola 2F

Step-up sessions and workshops are honestly a great method for tutoring. I recommend checking those out first since the TAs have an idea of what you need to know for exams.

Charisma Arreola 2F

Since they will be similar in style to an online recording, more students will be let in so try not to worry.

Charisma Arreola 2F

Reading the textbook before watching lectures has helped me to get an understanding of what his lecture can cover. It is best if you break it up and try not to read too many pages in one sitting so that you can take everything in.

Charisma Arreola 2F

I believe there is no curve, but the only grading exception is that a 50% is deemed as a C- for passing.

Charisma Arreola 2F

Memorizing the trend for electro negativity, and then remembering maybe five of the main elements should help you figure out the rest.

Charisma Arreola 2F

For those, mini flash cards really helped me when I was learning them in AP chem. Our teacher actually suggested it and it turned out to be useful.

Charisma Arreola 2F

I don’t think that there is a curve, but that his grading system has a wider range for passing.

Charisma Arreola 2F

Also, to study and feel like you have a firm idea of the concept, rewrite some of the facts/problems that are harder for you so that you remember them better and are able to feel more comfortable with those topics.

Charisma Arreola 2F

I highly recommend setting aside a few hours to do absolutely nothing but watch your favorite movie or show, and either have an herbal tea or a feel-good snack you may not always have.

Charisma Arreola 2F

Honestly, one of my favorite shows is Revenge, but I am not sure where they still may have it. Also, Criminal Minds, Lucifer, and Hannah Montana are all really good too!

Charisma Arreola 2F

My best recommendation is to study in intervals! Give yourself breaks and genuine “relaxing” time to let everything soak in. Also, coffee and energy drinks for that final push are GREAT. Find a study buddy and do zoom calls.

Charisma Arreola 2F

About to join, thank you!!

Charisma Arreola 2F

I believe you have to go to your class study list and change it.

Charisma Arreola 2F

I am pretty sure he said office hours and workshops would cover them!

Charisma Arreola 2F

Simple answer is it takes less energy the closer it gets to a noble gas

Charisma Arreola 2F

I think it is just a matter of what is given in a test or problem.

Charisma Arreola 2F

The end of a noble gas shows a full electron level, which is why it is easier to use a noble gas as a shorthand configuration.

Charisma Arreola 2F

Some more chemistry jokes?

All the good ones argon.

Charisma Arreola 2F

I try to tell chemistry jokes....

But there is no reaction.

Charisma Arreola 2F

I believe these are a combination of p=mv and E=h/c

Charisma Arreola 2F

No, but I believe he said it will be on the second midterm.

Charisma Arreola 2F

It is much easier to remember the second option, and since that is the option we use more on sapling I would suggest using that one.

Charisma Arreola 2F

So you will need to compute using E=frequency x wavelength and use that to complete the kinetic energy equation.

Charisma Arreola 2F

The password should be LL14A20, I would double check your email though!

Charisma Arreola 2F

My TA said as long as a webcam shows our work that we aren’t accessing other tools it should be fine!

Charisma Arreola 2F

If you have another laptop or phone to use, you can log onto your zoom and use it as a webcam I believe.

Charisma Arreola 2F

I believe you will because I am currently doing the same thing. My TA said as long as I have an external webcam for the zoom during the midterm, I should be fine.

Charisma Arreola 2F

Most of the time you will have to reference the formulas to find what they’re giving you and solve from there!

Charisma Arreola 2F

An electron is only ejected if it has become too excited for the current level it is in, and can not jumo into a new level.

Charisma Arreola 2F

From what I understand, the farther light travels, the more extensive the wavelength is. I think that this does cause energy to lessen over time, but I have not done enough problems to actually test that.
