CHEMISTRY COMMUNITY

Meredith2E

Don't know why but winter quarter was way more challenging than fall quarter. It was just difficult to find enough motivation to work on school stuff but like someone mentioned, we're kinda basically paying for our education so you can't exactly slack off. It's also depressing knowing I spent more t...

Meredith2E

I definitely feel relieved. I felt like I was going to get stuck somewhere and run out of time or that the questions were going to be difficult. But the final was very fair, it was nicely balanced with lots of time to remaining to take it slow. Can't wait to return to in person classes though, it ma...

Meredith2E

I'm not too sure, you should definitely ask your TA. Most might mistake your highlighting as you trying to sneak in extra information, so it would be best to keep it blank. But usually, TA's just ask to see if you have it and aren't too picky.

Meredith2E

I just miss the experience of it all. Like the freedom of it all. Waking up and getting breakfast knowing I was about to doze though that 8am bio lecture. Meeting up with friends for lunch. Going home to my roommates (miss u chesca) and just spending time with everybody. (Definitely do not miss the ...

Meredith2E

Mostly focusing on the textbook problems, trying to get though as many as possible and doing any problems that I find challenging over and over until I nailed it. Besides that, just attending any extra sessions with the TA's and such for extra work.

Meredith2E

If you didn't do last weeks chemistry community posts, then essentially you would be missing out on five points, since technically its five points per week for the five posts you make. Some TA's have been pretty lenient in which they let you make it up by posting more the next week, but then again, ...

Meredith2E

Definitely going to miss the step up sessions. But I think I'll just be taking advantage of the professor's office hours and also the TA's.

Meredith2E

There isn't a "study guide" exactly, but the closest thing to that would be the outlines that Lavelle provided for us. You can always check and see what topics you don't feel so confident about and review. Plus, there's always review sessions. Last quarter, Lavelle provided us with so many...

Meredith2E

Can't believe it's been a year since the whole pandemic began! So crazy. But this spring break is something we've all be looking for. The honest truth? I'm probably going to spend spring break catching up on shows I've wanted to binge watch and just spend time NOT worrying about school and literally...

Meredith2E

The burnout is real. It has been very exhausting lately to focus on class and do schoolwork. I feel like it helps a lot when I stay organized and break down everything I need to get done. By telling myself to do half of the sapling hw by a certain day and then sticking to my to-do list, I find mysel...

Meredith2E

I used to take hand written notes at the beginning of chem 14a and I felt it was helpful. Sure, I would have to pause lecture recording a couple times to keep up but it wasn't so bad. This quarter I started taking notes on Good Notes and it's so much easier. Any diagram we discuss in class or any pi...

Meredith2E

Looking at what you wrote, I feel like the only problem is your format. In which you're writing 2OH-(aq) as 2OH(aq)-, with the - coming after. Maybe you can change that and put it before. But for this problem, I got the same answer essentially. Cl2O7(g)+4H2O2(aq)+2OH-(aq) ---> 2CLO2-(aq)+4O2(g)+5H2O...

Meredith2E

I feel like studying for the midterms wasn't as overwhelming since I only focused on the topics we were learning (focused on the things on the outlines). But since the final is cumulative now, I don't have a set plan on how much I should focus on certain concepts. Finals are never easy. For 14A, I f...

Meredith2E

First, you need to solve for Ecell, in which you can use the link from the problem to find the standard reduction potentials. Once you find that, its all about plugging in the values you have into the question ΔG∘=−nFE∘cell and you're set. A more thorough explanation would be to write down your two ...

Meredith2E

I was having the same issue last time with week 5/6 homework. I just closed all my tabs and then opened it again and it worked fine. I've only had that issue when I use safari which is weird, so I stick to google chrome now for homework.

Meredith2E

Yeah, even if you reach the 50 post mark, you can still continue to post and help out others. Any additional post won't be like extra points or anything. Plus, you still need to be posting 5 times a week so they won't like stop you from posting even more.

Meredith2E

I haven't exactly binged watched anything. It's more like I'm waiting on new episodes of different shows a week. A current fave has to be sk8 the infinity tho :)

Meredith2E

What has everybody heard about Castillo? I kinda just went in and enrolled in any available spot. Lavelle has totally made chem better, kinda wish he could teach me the rest of the chem series lmao.

Meredith2E

I made sure to save the new WandaVision episode until after the midterm lol. It felt so nice to hop back in bed and pull up the episode and just nap! Seriously, sleep felt like such a good reward after all that time studying. But back to the grind again.

Meredith2E

It's better to sign up now and save a spot since they're starting to fill up quickly now. That way, you can at least have a spot and not worry about it once they release the names of the professors.

Meredith2E

They released the score for the first midterm in less than a week I believe, so I'm assuming it'll be the same this time. Hopefully by the end of next week, so possibly by Friday :)

Meredith2E

AHH so relatable. I feel the same way, in which I tend to burnout right before an exam. I feel like it happens a lot more with zoom school than in person school. I think I've just focused too much on school, in which I havent given myself enough time to relax. Like there's always something due and a...

Meredith2E

I plan on taking Chem 14c along with Physics 5c and Stats 13. That is if I'm lucky enough to score any spots. Im just torn between adding chem14bl to the list or just saving it for summer (but then again I need to take Chem14CL). So basically I'm not looking forward to next quarter lol. Anybody in t...

Meredith2E

It says online but that doesnt exactly mean that they're recorded. It's best to check with students who are taking the class right now with the specific professor to see how class is done. Or look into how the professor is doing their classes in general.

Meredith2E

Hi, I was wondering if someone could explain how to do 19 ? The problem is: For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 bar for all species. For the reaction C2H6(g)+H2(g)↽−−⇀2CH4(g) the standard change in Gibbs free energy is ΔG∘=−32.8 kJ/mol. What is ΔG for th...

Meredith2E

Last quarter, the final felt harder, just because there were more questions and it covered the content of the entire quarter. So unlike the midterms where I focused on specific topics, I had to make sure I studied and brushed up on everything.

Meredith2E

I feel like Sapling hw lets you test your knowledge and help you nail down the process. Like learning how to solve for things. Then you can use the textbook problems to apply what you know and get a feeling of how problems on the midterm will be. Both are very helpful.

Meredith2E

Is it wrong to say that I'm only tuning in for the halftime show lmao ? Boutta do some chem hw and jam to The Weeknd.

Meredith2E

As mentioned above, you should be subtracting by 45 rather than 25. If that doesn't give you the right answer then something must have gone wrong when you were setting up your equation.

Meredith2E

Mine was also off last quarter, but by the end, I was given full points. I'm guessing it takes a while to update?

Meredith2E

Yeah, I've felt the same way. Online school can drain all of my motivation sometimes, and I end up stressing myself out by forcing myself to think about what I have to complete. At the end of the day, something that has really helped me is setting up a to-do list and like a semi normal routine. With...

Meredith2E

Usually it all depends on your enrollment time. A lot of people get luck with an early time and are able to snag a spot. But an issue with remote school right now is that there is sometime not enough spots offered. I do believe chem 14c might be a bit tough to get considering a lot of us need to com...

Meredith2E

I'm trying to knock out the chem series as soon as possible. Plus, I feel like taking it back to back will help keep the information fresh in my mind. So I'm rooting for a spot in both 14c and bl to knock them both out with one quarter. But yeah, like others have brought up, my enrollment times have...

Meredith2E

Last quarter, we were able to see our scores in about a week. So I'm sure it will take about the same time considering the fact that the midterm template was just like last quarters.

Meredith2E

I'm planning on taking it next quarter with Chem 14C. I was planning on taking it this quarter but after how terrible my enrollment time was, I wasnt able to [censored] a spot so I'm hoping that this upcoming quarter is easier.

Meredith2E

One of the things that made school easier (when in person) was having a routine. And so I began applying the same thing at home. Sometimes I feel so unmotivated and some days are harder than others to get out of bed. But by slowly setting up a routine, it's like I have something to do and a reason t...

Meredith2E

The midterm should be 50 mins long and in terms of number of questions, its not determined yet. The first midterm in 14a was pretty short, in which a lot of us finished with like plenty of time to even double check and even had like ten mins left. But I believe it just ranges from test to test. Fing...

Meredith2E

The outlines themselves are super helpful since you get to narrow down what you should specifically know by the time the midterm comes around, and the textbook problems are also super helpful. The better you get at doing those, the easier the midterm felt (at least for me last quarter.)

Meredith2E

Yeah, last quarter we were allowed scratch paper and a print out of the periodic table. I just printed the one that Lavelle has on his website and that worked well.

Meredith2E

Not gonna lie... Legally Blonde is probably my go-to movie. Like that movie hypes me up and it just motivates me because Elle Woods went to Harvard and studied law and kicked [censored] and it's like, if she can do it, then I can make it through college too. And when I heard that they filmed a shot ...

Meredith2E

Last quarter I used a graphing calculator and it was no problem. If this was like an actual in person midterm, then they usually make your clear the memory on your calculator and show it to the TA who is proctoring, but that would take up too much time when doing it online. But yeah, any calculator ...

Meredith2E

I'm pretty sure there still will be a lecture. Last quarter I remember there was a holiday like on a Friday and we still got all three lectures, so it might be the same here since they are recorded so technically you can give yourself Monday off and just watch lecture the next day lol.

Meredith2E

Pretty sure Lavelle will send out an email to clarify what we should focus on when reviewing (bless his soul).

Meredith2E

Last quarter we were able to see our scores in MyUcla and they were updated like every other week. So you just had to make sure that you were receiving the correct amount of points. I believe Lavelle would also send like emails to remind us that the scores updated and to check.

Meredith2E

Yeah, last quarter I would use Sapling by just clicking on the link on Lavelle's cycle website and it would work perfectly (using safari). But I can't do this same this time, so I just switched from safari to chrome and it works perfectly (kinda strange though).

Meredith2E

Does anybody know if this glitch has been fixed or if Lavelle has addressed it?

Meredith2E

Last quarter we took the exams during our discussion section, so ideally we set up zoom so that the TA can watch us while we do the exam and we used Respondus which is just a browser lockdown. It goes pretty smoothly during the exams, which is very nice. I'm assuming it will be the done the same exc...

Meredith2E

The TAs will definitely be tracking your posts starting week one until the end of the quarter and you get credit for completing the 5 per week. So ideally, you should reach the 50 post mark.

Meredith2E

The chemistry community points don't carry over. It's a new class technically so that means new points and starting from the bottom. Plus, the chemistry community points don't carry over in general.

Meredith2E

Dude this is so clutch! Thank you!

Meredith2E

Usually, just to spice up my studying, I go on YouTube and listen to slowed/reverb music since its calmer and I can totally hum along as I do my work.

Meredith2E

Yeah it's going to be just like the final except that when in the zoom with our GAs, there's going to be someone else proctoring so that we get split up and its easier to monitor everyone.

Meredith2E

Yeah he didn't call it weak, so I have just been assuming it was a strong acid.

Meredith2E

AHHH LOVE THIS! We all got this, we have to finish strong. Thank you for the reminder!

Everybody remember to eat, sleep, stay hydrated and just take care of yourself (I know we can all get caught up studying and grinding during week 10 and finals week.) Good luck to everybody.

Meredith2E

Definitely going to do the textbooks problems since they seem to help me master the concepts more than the sapling hw. But Lavelle has a bunch of review sessions planned which I highly appreciate and will most likely be attending. Besides that, I'm just trying to go over anything and kind of have it...

Meredith2E

Most likely a no. I don't think any professor really offers extra credit for them, just because they're anonymous and there's really no way to keep track if somebody does them or not. But it's really helpful if you fill them out since it helps the professors prepare better for the next quarter.

Meredith2E

I think flashcards are the way to go, just because they're so easy to make and you can easily quiz yourself and have others quiz you. If you want to get even more creative, maybe make something interactive like a kahoot? I can't think of anything else lol.

Meredith2E

This quarter has just been so hectic. But now with finals being literally around the corner, I feel like so much information is being thrown at me so its been a lil rough. Can't wait to finish my last final and just enjoy winter break. We all deserve a break no joke. Hopefully winter quarter is easi...

Meredith2E

Bless up! I was really looking for videos that could help me study and these are really clear and easy to understand! Thank you!

Meredith2E

Under test and exam schedule on Dr. Lavelle's website, it says that the final will be on Sunday December 13 from 11:30am – 1pm. There is also an alternative time for international students. Hope this helps! :) Does this mean that since we are taking it between 11:30-1 as a entire class that it'll b...

Meredith2E

I try to go by the outline that he has. So based on the topics we’re supposed to be learning or must master, I try to watch videos from youtube that go over them (mostly because i’m a visual learner and most youtube videos just go straight to the point.) When it comes to studying for the midterm, I ...

Meredith2E

That’s a good question, I honestly thought they were the same thing lol... like you can say radical or free radical and mean the same thing but now? Not so sure.

Meredith2E

^Thats what i had as my third structure and it was correct :)

It’s so tedious doing drawing these on Sapling, definitely not my favorite type of problem lol.

Meredith2E

^Yeah I agree with Chesca.

Lavelle hasn’t said anything yet but since finals are quickly approaching, i’m sure he will soon address it to give everybody a chance to accommodate their schedule (in case it conflicts with other things or figuring out the time difference issue).

Meredith2E

Oh dude same, i skipped this problem. Gonna keep an eye on this post so i can get some help too lol.

Meredith2E

It would be a nice break to not have lecture, but who knows, he might make it a short one at least.

Meredith2E

If the grades are posted this week, I’ll pretend I do not see it and enjoy my thanksgiving first lmao.

Meredith2E

Usually I treat myself to something, like eat some candy or ice cream and watch a movie in order to relax and just get my mind off of the midterm. If i have nothing due like school wise such as homework or labs, then I try to distract myself by spending time with my family since i usually keep to my...

Meredith2E

I felt better about this one, in general I felt more confident since I kinda fixed up my study habits. But you bet after that midterm I put on a holiday movie and relaxed :) Make sure to take care of yourself ! (Seriously can't wait for my much needed winter break)

Meredith2E

I'm not exactly sure, I mostly try to estimate my grade based on the points I'm receiving (like getting points for chemistry community, the hw, etc). And then based on how my midterms go, I try to see what range I'm in (like whether I'm passing or not lol). I don't think Lavelle has specifically sa...

Meredith2E

The textbook problems definitely come in clutch! If there is any specific topics that I still dont understand, I tend to watch videos (YouTube) since I'm more of a visual learner.

Meredith2E

My TA mentioned how we should have trends such as ionization energy, electron affinity and atomic radius kinda nailed down (to make it easier on us) and added that we can also tell nonmetallic & metallic character as well (so thats another trend to know if you're a hardcore chemist lol).

Meredith2E

Usually after seeing a midterm grade, I tend to take a breather/break to focus on myself and not let myself get too anxious about my grade. And then I just focus on lectures and improving my studying habits (its been wayyy harder to study at home that I expected compared to campus). But I've learned...

Meredith2E

Waittttt this is great! I was literally about to post a question about video recommendations on this! THANK YOU!

OMG JUST DANCE! I remember begging for a Wii when I was younger and im so sad that they stopped releasing new just dance games :( But you can always count on just dance for a nice grind/workout lmao.

Meredith2E

Yeah they haven't really been clear with how many questions EXACTLY, but it would be a lovely thanksgiving gift if they would keep the questions to the same amount as the last midterm (HINT HINT @ LAVELLE).

Meredith2E

I'd recommend Money Heist, Criminal Minds, The Vampire Diaries, The Originals and Legacies. :) If you know a specific type of show that you like, I can come up with more ideas, those are just some recommendations. Dude Criminal Minds is golden (fave character?). That is literally my comfort show, a...

Meredith2E

Not sure if the midterms will be curved, I think the class did pretty decent overall so they might not adjust anything. Some say that Lavelle adds a couple of points to boost our grades but thats about it.

Meredith2E

Literally the main difference that I remember them by is that ionic bonds mean atoms transfer electrons to one another while covalent bonds share the electrons. One like to give and the others like to play nice and share. (The most basic rundown lol)

Meredith2E

THANK YOU ALL FOR THE HELP! This really does clear it up :)

Meredith2E

Yeah they don't carry over. 5 per week (although if they did carry over, that would've been nice).

Meredith2E

Might be an obvious answer, but can anybody explain what is the difference between resonance structure and resonance hybrid?

Meredith2E

Literally same, one of the many perks of chemistry community. Literally Lavelle's entire intention when he created this community lol.

Meredith2E

LDF is the weakest type of intermolecular force. Wait why have I never heard of LDF. Did he go over this or is it just a type of universal chemis...

Meredith2E

In lecture, Lavelle mentions how radicals are an exception to the octet guideline but I was wondering if that is the only possible exception to the octet guideline?

Meredith2E

In the Sapling Hw, we have a question that asks which molecules exhibits London Dispersion Forces. Does anybody know what that means or how to determine if a molecule does have such force? I'm guessing this is something that hasn't been covered in lecture yet unless I missed it.

Thank you!

Meredith2E

As far as I was concerned, I don't remember being told that discussion was mandatory but that it was recommended since most TAs go over the topics that we covered in lecture. I think if you just missed one discussion you should be fine (that is assuming that it counts towards grades) but double chec...

Meredith2E

I think just to be safe, have the 20 posts by this Thursday since they are doing a grade update. And then make sure to keep it up and have the total points by the end of the quarter. Better safe than sorry ya know.

Meredith2E

Has anybody asked like their TA's or Lavelle about this? Since the midterm is coming up soon.

Meredith2E

I mean, they do want us to get it right but I feel like if you're off by a sig fig they cant just not give you credit. Although thats a good question. Some professors are pretty strict on units and stuff.

Meredith2E

My TA mentioned having access to the equation sheet but I think to be sure, you should try to remember really important equations in case we're not provided with it. I think Lavelle will clearly state whether we are provided with it or not soon since the first midterm is coming up soon.

Meredith2E

Inclusive access is basically a program that lowers the cost of required course materials. For example, for Physics 5A you're asked whether you want to opt in or opt out. This just means whether you choose to be in the program or would rather not and get your materials for class from a different pla...

Meredith2E

THANK YOU ALL FOR ANSWERING!!

I ended up sticking with just 110 as the molar mass and just kept in mind the whole “window” thing, and yes @Dominic, I did end up multiplying by 2 in the end when I got the molecular formula.

Meredith2E

So as I'm going through the Sapling hw, I come across a question where it gives me the molar mass as "110±10 g/mol." I don't know why but this really stumped me and I can't seem to understand what it means. I've never seen molar mass written in that form so if anyone can explain that would...

I do have the groupme for this class, but I was looking for the discussion one. I know a lot of people posted links but I couldnt seem to find one particular to 1C.

Meredith2E

This may have been asked before but I couldnt seem to find a group me link for Discussion 1C, so if anybody can link it down that would be nice, thank you!

Meredith2E

Lavelle offers a bunch of resources, mostly so that we can ask questions since everything is online and recorded. Its fine if you dont have questions lol, maybe something will come to your mind as you listen to what others are asking, or maybe you'll hear someone ask something that you had previousl...

Meredith2E

I think that if the question is asking for you to solve for something specifically like moles, then you use those units. But yeah, overall mostly use the units the question is asking and if not, then SI units would work best. At least that's how I've been doing lol.
