You have to go to the TA office hours and I believe we are not allowed to write down the questions and answers, hope this helps for 14B

805421690

I'm assuming it's just a general/typical straight scale where: 93%-100%: A 90%-92.9%: A- 87%-89.9%: B+ 83%-86.9%: B and so on... However I'm unsure about the cutoffs as the percentages get lower because you need at least 50% for a C- Do you happen to know the minimum for the the class before you ge...

It is 5 posts per week! By the end we should have 50, hope this helps!

805421690

hi! I was wondering if anyone had any tricks or tips for memorizing/knowing the general area for metals/nonmetals/metalloids on the periodic table?? thank you! Once you learn staircase it becomes very easy! you can try searching up videos on YouTube if you are a visual learner as well, hope this he...

the anode is always on the right of the cell diagram and the cathode is on the right.

I thought the anode is always on the left of the cell?

Organic Chemistry tutor is a great resource found on YouTube, where there are other amazing tutors that will show you step by step how to answer problems and give you different teacher-point of views for learning topics in chemistry

805421690

Yes all of them are multiple choice!

805421690

I believe anything greater than a 93 or maybe a 94 will classify the A as an A+

London Dispersion Forces are synonymous with Induced Dipole-Induced Dipole, Van Der Waals, and Dispersion forces. These type of intermolecular forces tend to appear in all molecules, and when non polar molecules interact with each other they only experience LDFs. Great simple answer to this, also r...

Thank you!! The last group me helped me stay on track, hopefully for 14B I will perform better

805421690

only for anions :)!

805421690

Making an outline of important topics we learned each lecture first, and then going on YouTube to see multiple examples on how to solve and identify those topics through organic chemistry tutor helped me a lot! I am not a student that can learn by themselves by reading textbook problems, I like to h...

This is a great way to memorize which acids and bases are strong thank you!

805421690

click on your name and it should tell you how many posts you have. Just remember each week requires 5 posts so remember to account for that when calculating if you get all your participation points. If we didn't do a full 5 one week, but then made up for it the next week does that count? Like only ...

Nope, these are different chemical processes. As I understand it, Ocean Acidification is a phenomenon driven by the increased atmospheric carbon dioxide we are producing while acid rain comes from sulfur and nitrogen oxides released into the air. Ocean acidification comes from the high atmospheric ...

The lockdown browser pops up on the search bar on the right side on apple devices, and once you take the test it will pop up for you to use and quit all your open tabs! hope this helps

805421690

The professor might have you as waitlisted but everyone eventually is enrolled into the class when the quarter starts still do all the homework and assignments while you wait to officially be enrolled, hope this helps

805421690

Honestly I never really relied on the book, I am not a reading-learner, instead I relied heavily on organic chemistry tutor on YouTube and he is amazing! I hope this helps for the next chemistry quarter

805421690

I wonder if more quizzes In this course would make students study more throughout the weeks instead of before big tests like the midterms and final

805421690

You click on quick links on the top left of the screen, and just click on "Your Posts" underneath it! also, I just figured this out today lol!

805421690

I took chemistry my sophomore year of Highschool, a basic course. I definitely struggled a lot doing this quarter's chemistry and I will say I wish I tried to do a beginners course at my local community college to refresh my memory!

805421690

I just wanted to ask, are they Able to see the posts you make under one topic or will they only grade the ONE post?

805421690

This is a bit late, but you might want to check out Alpha Chi Sigma, the chemistry fraternity here. They offer free tutoring by appointment. Here's a link to their site: http://www.chem.ucla.edu/axe/tutoring.html I did uotknow they even existed, thank you so much definitely will bemusing this for n...

If all of the stoichiometric coefficients were different, the unique rate can still be the same using any of them to calculate it because we are multiplying the (change in concentration/change in time) by 1/coefficient. This therefore allows us to calculate the unique rate using any of the species ...

Watch Evil on Netflix!!! It is so good, although it is on the scary side but it definitely has its funny moments! For sure a binge watch series

805421690

Thank you so much for posting this, I really needed to hear this especially after/during my finals

Does anyone know the best water brand that is healthier to drink, I heard of the most common brands being actually acidic and poor in health for us to drink!

805421690

Quick question, does anyone one know the the intensity of 14B compared to this class? Will it increase in difficulty or be a little bit more easier ? Thank you!

805421690

Does anyone know how many extra points we received for the course evaluation? Will it impact out grade in a negative way if we did not complete them?

805421690

For some reason it says I did not complete the amount of posts I know I did... I think because I replied multiple times under the same post. Does that mean those posts do not count?

805421690

Build my confidence! in every aspect, whether it be my confidence in my intelligence or physically or communication wise

805421690

acid: (-log[H+]
base: 14 - (-log[OH-])

805421690

I am curious to know that if we do all of the chemistry community statements/questions, and homework, will that give enough boost for the final grade? In a situation where you performed poorly on the tests

805421690

Does anyone know that if you fail this class will you be able to still take 14B next quarter?

805421690

I believe that it is almost like a curve, if you get a 50% he will pass you with a low C.

805421690

This final was definitely no joke. I did poor on the first midterm because of poor studying habits but I did great on the second one. However this final for sure humbled me, I am hoping for the best currently

805421690

Over hundreds of students that need to be graded, they should be posted soon enough I know the professor is swamped with the amount of students. I hope he has an amazing break after all that grading

805421690

This might not be relaxing, but I am definitely planning on also being productive over break with my projects. One is my clothing brand called PlayGirlzLA on Instagram and twitter! And the other is my nonprofit organization called H5foundation one instagram!

805421690

I'm gonna spend time with my parents and try to get outside because it feels like I've been cooped up for the past two weeks. Definitely catch up on some shows and maybe read for fun. Also sleep in! Do you have any interesting Netflix shows/movies and books that you suggest! Definitely planning on ...

805421690

Definitely going to get my sleep in for a few days and lounge around! All of these late night study groups and early morning independent study times have taken a tole on my energy and sleeping habits. Of course after that I want to maybe go hiking, go to the beach, go bike riding, just be OUTSIDE.

805421690

I want to work on becoming more focused on academics, specifically finding the motivation to be interested in school. Being outside of the classroom definitely has had a negative affect on my participation with my school work. outside of academics I also want to begin a healthier lifestyle including...

805421690

Does anyone know what we have to score (Minimal) on the midterms and final in order to pass the class?

805421690

Remember to get enough sleep, I know a lot of us try to do cram-studying the night before, but this should be the night you go to bed early! Also hydrate and eat a good meal before taking the test, it may seem small but it goes a long way! Good luck everyone!

805421690

Does anyone know how to calm down your anxieties before you take this final? Since having test anxiety can be very distracting while you're trying to study or even while you're taking the test itself. Open to any tips:) I find it very helpful to put on meditation music or just nature recordings of ...

805421690

Thank you so much for making chemistry something to look forward to, the overall flow of the class could not get any better! I wish we could have came to class instead of doing everything online.

805421690

How do we solve a lewis dot structure? I know for the first step we have to find the total number of valence electrons correct?

805421690

I usually keep it to three, unless the fourth one is higher than five. If it is I just keep it to if I am calculating that number, but if its for the final answer I just round it up or drop it. Hope that helps

805421690

Do you guys know if we use Oxygen's mass as 15.999 or just 16.00, I kept getting different answers online when looking at the periodic table and was wondering which one is most preferred or does it even matter? Thank you!

805421690

I try to remember molecular formula as an exact proximate, just like on the periodic table everything is approximate, therefore for this formula we do not use ratios but instead the approximate number of how many atoms there are.

805421690

I always get confused with the ratios for empirical formula! For example if I simplified the molecular formula by 2, and yet I can simplify it again by another number like 3, is that allowed? Or do I keep it simplified by the first number in this situation which is by 2? Thank you!

805421690

Hey guys, I think the hardest part for me with sig fig was trying to remember the rules. So I wanted to share the easiest way to explain how to find significant figures: 1. Any # greater than 0 is significant 2. Any number between a significant # is also significant. Meaning if it qualified for step...
