Honestly I'm planning on rereading some of my favorite books when I was younger like Harry Potter, and binging everything I've put off during the quarter like His Dark Materials on HBO.

I just wanted to wish everyone luck on whatever finals they have this week! I also wanted to ask if there's anything you've got to keep you motivated to finish the week. For me, I'm just looking forward to have some free time to binge shows and read some books that I've been putting off since October.

I get ready bad anxiety just before a final so before it happens I try to have some kind of routine to keep my mind occupied. Since this final is earlier in the day I made some coffee because the routine is so calming, though I don't know why exactly. Making any kind of food or snack helps, but I ge...

Typically I like to study by playing music but I've now started to find myself getting distracted by that, but I definitely need some background noise to focus on my work. I like using those pomodoro technique videos on youtube, but I was wondering if there's any other methods or things you guys use...

How exactly do we get polarity from the elements in the structure, I understand that the arrows represent the pull of the elements but I'm still struggling to fully grasp it any further than that.

Jade Lastra 3B

I think it's good to look in the textbook I think I remember someone mentioning that some questions are literally straight from the textbook, and even if they aren't the same they tend to be the same format.

Jade Lastra 3B

so I'm almost finished with number five, which I don't know how the different numbers look but this is the one I was given: Determine the [OH−], pH, and pOH of a solution with a [H+] of 6.7×10−9 M at 25 °C. and I've been having trouble with getting what [OH-] is. What I've been doing is dividing 1x1...

I think that tends to happen because too many people are on the cycle at once, so sometimes I'll just wait a few minutes and try again.

Jade Lastra 3B

I think everything will be the same except it's not going to take place during our discussion time.

Jade Lastra 3B

I think they will but can anyone confirm if the final exam will be more focused on older content rather than new content?

Jade Lastra 3B

I like to watch videos on youtube that give examples as well as look over the textbook problems. There's also quizlet flash cards that help with review.

Jade Lastra 3B

I'm having some trouble with trying to figure out the structure for number twelve and was hoping someone could help me figure out what I'm doing wrong.

Jade Lastra 3B

I think most people mentioned this already but taking break is important, but also I always tend to feel guilty for taking them because it feels like I'm wasting time. Which just does more harm than actually help me so when I take breaks I try to actively get my mind off of the activity by making a ...

For this question since the lone pair is present in the central atom that means it would be slightly less than 109.5, so it would just be 109.

I wanted to wish you guys a Happy Thanksgiving and ask if there's a tradition your family partakes in every year?

Jade Lastra 3B

I 100% feel the same way, and am just trying to get as many possible points to try and pass. If it helps the community post and homework do a lot of work to help me pass. Also don't feel to bad if you have to re-take the class, it's a lot more normal in college than it is in high school.

If he does he'll probably make it a short one, hopefully.

What's a chemistry teachers favorite thing to teach about? Ammonia, because it's pretty basic stuff.

Jade Lastra 3B

I was wondering if we would have to memorize all of the shapes and angles for the VSEPR models or if they would be given to us?

Jade Lastra 3B

So I've officially finished the second round of midterms for my classes, and was wondering how you guys de-stress after midterms or finals?

Jade Lastra 3B

If the videos are having a problem I normally refresh the page, or it may just be better to watch the second version of the lecture.

Jade Lastra 3B

Why should you go drinking with neutrons? Because wherever they go, there's no charge!

Jade Lastra 3B

so with structure c it would have the double bond between N and C and because of this the N would get one positive charge and both O's would get a negative charge right?

Jade Lastra 3B

I'm having some trouble trying to find the resonance structure for number four on the homework and I was hoping for some help on trying to approach this one.

Jade Lastra 3B

I always like to watch tv as a background noise while I work so I'll normally go for something predictable like a procedural show like Criminal Minds or NCIS. If I'm not working then I love to watch Derry Girls, it's a really fun show and super short.

Jade Lastra 3B

I always find that looking over a video on youtube helps, or going through older examples on the homework. I don't know if Lavelle does this, but I know some professors will post older midterms for students to review. Those always help me get an understanding for what the general format is supposed ...

Jade Lastra 3B

I was wondering if there's a session to go to that'll go over the last midterm?

Jade Lastra 3B

For the chemistry community post do we always have to have five done each Sunday, or does it have to accumulate to 50 by the end of the quarter?

Jade Lastra 3B

just did the problem and it worked! Thank you!

Jade Lastra 3B

so for my second problem (I'm not sure how this one looks for everyone else) I need to show a negative 2 which in class we did with the brackets around the structures. So I was wondering how to show that one sapling?

Jade Lastra 3B

I just wanted to check that the homework would be due next Sunday at 11:59pm not tonight, right?

Jade Lastra 3B

Could someone help me understand exactly how to break down this question and set up the equation?

Jade Lastra 3B

so I was able to figure out the spectral line and the wavelength for n=1 and n=7, but the second part says it's wrong. So for the second one I'd use n=6 and n=7 and use v= (3.29x10^15)((1/6^2)-(1/7^2))

Jade Lastra 3B

I've been struggle over how to get the chemical symbol for the element with the ground‑state electron configuration [Ne]3s^2 3p^3 and wanted to check my reasoning which is to add the 10 from Ne and the 5 from the given configuration, right?

Jade Lastra 3B

I was just clarifying that if we're using our phone as an external camera that's the only one we need, right? We don't have to use our laptops as well, just the phone?

Jade Lastra 3B

I've not been studying for the midterm as much as I planned to and get a lot of anxiety on test over setting up equations (specifically the quantum ones). What are some of the easiest ways to break it down, and also how to get over some test anxiety?

Jade Lastra 3B

What exactly are the importance of orbitals in terms of what we're focusing on right now in class?

Jade Lastra 3B

I wanted to double check if we should print out certain equations/ the periodic table, or if this is gonna be given to us in the midterm?

Jade Lastra 3B

Are there going to be any last minute review sessions before the midterm?

Jade Lastra 3B

To clarify, the answer of the equation is a way for us to know exactly what the orbital looks like, right? So it's similar to the lewis dot diagram?

Jade Lastra 3B

Is the quiz for today for points that counts to our grade, or is it more a practice quiz to do a run through of what it will be like for the midterm?

Jade Lastra 3B

Did you know that oxygen went for a second date with potassium?
How did it go?
It went OK2!

Jade Lastra 3B

I'm having some trouble finding respondus, and was doubling checking if it was on CCLE or somewhere else?

Jade Lastra 3B

I was looking through my notes from the Monday lecture and wanted to know exactly how the cross country analogy connects to quantum mechanics.

Jade Lastra 3B

Does anyone have any good links to quizlet flashcards that they're gonna use to study?

Jade Lastra 3B

Can we use our phones as an external webcam? I've seen so many different answers and was wondering if there's been some clarification about if we need to buy an actual webcam or not?

Jade Lastra 3B

I definitely agree to show as much work as possible when it comes to problem like that because I personally always find it to find me keep track of what is what. Also so anyone who is looking over my work can see exactly what may have gone wrong.

Jade Lastra 3B

I was hoping for some clarification on the school of thought for when it comes to classifying the different number into the correct sig fig categories. Specifically how 3000 goes into one sig fig instead of 4 sig fig, etc.

Jade Lastra 3B

I'm pretty sure that the homework is due Sunday at midnight

Jade Lastra 3B

I've been over this equation a million times and keep getting it wrong, and was hoping someone could point out the error in my calculations or set up. I've attached a screenshot of my work for number 6 (which hopefully shows up). Thanks for all of the help and clarification from the previous post!

Jade Lastra 3B

I'm having trouble trying to learn the difference of setting up how to find moles and molarity for number 6, and was wondering if someone could help me get a clearer understanding the thought process of it?
