Hello! To solve this problem, we need to know three steps that involve finding the standard molar entropy of vaporization: the entropy change heating water from 59.0 °C to 100 °C, the entropy of vaporization of water at 100.0 °C, and the entropy change cooling water from 100 °C to 59 °C. To solve t...

Thank you everyone for these great suggestions. :)

Giselle Simmons 2D

For example, when doing work I love listening to Still Woozy, Frank Ocean, and Sky McCreery.

Hey! Please drop some artists you guys enjoy listening to when studying or doing homework.

Giselle Simmons 2D

I'm a pretty big fan of Rita's Gate of India.

Giselle Simmons 2D

It's unfortunate, but so many people I know have been getting Covid recently! It seems that we won't have in-person classes for awhile. My friend was even saying he wouldn't be surprised if we got sent home :/

Giselle Simmons 2D

Sushi is a classic. Also, Thai and Indian food slap every time.
As for campus, I'm always down for that lemon poppy seed bread.

Yes!! Miyazaki movies are the best. I also love My Neighbor Totoro and Howl's Moving Castle.

Giselle Simmons 2D

For a show, I love The Great British Baking Show. The Christmas version especially is so relaxing to watch.

I wholeheartedly agree. Ratatouille is cinematic gold.

Giselle Simmons 2D

Thank you so much! I was wondering the same thing.

Giselle Simmons 2D

Wondering if anyone has read novels by Haruki Murakami? My brother loves his book such as Kafka on the Shore... curious if anyone else would recommend.

Giselle Simmons 2D

I loved The Honey Bus by Meredith May.

I would be down to start one honestly.

I just had boba!! Is there a chemical reason why sometimes the boba pearls are hard and sometimes they are softer? I thought this was a good question so I looked into it! Heat and water trigger the gelatin of tapioca flour, and the end product is a tapioca gel ball. As more hot water flows into the...

I also find it very helpful to work and study with a peer who is in the same class! They can help explain concepts you are stuck on.

Giselle Simmons 2D

Why was the mole of oxygen molecules excited when he left the singles bar? He got Avogadro's number!

Giselle Simmons 2D

I was so excited to see my pug, Bentley. It was a much-needed break before finals.

Giselle Simmons 2D

it is less than 2 days before the final and i am extremely worried about my grade, considering how i did on the second one. at this point, i think all we can do is just study, try our best, and hope that we get the best outcome possible. but we also have to remember that grades don't define us. we ...

Giselle Simmons 2D

Also Naruto <3

Giselle Simmons 2D

Arrested Development, Breaking Bad, Bojack Horseman, The Queen's Gambit, Bridgerton, The Great British Baking Show lol

Giselle Simmons 2D

I have mono which is ROUGH but other than that I have been pretty well! Just excited to finish off my first quarter at UCLA. :)

Giselle Simmons 2D

I get to visit my best friend who lives in AZ and then we're flying back to Santa Cruz together! We're hoping to go snowboarding too.

Giselle Simmons 2D

I am a little stressed but I am confident in Lavelle's teachings and all the help of the TA's! Mostly, I am excited for the final tomorrow because it feels good just to get it done you know.

Right, the Glass Animals really caught me off guard.

Giselle Simmons 2D

Also shoutout to Kate Santoso and Matthew their review sessions are fire.

Giselle Simmons 2D

Thank you, Sofia!! You will do amazingly I am sure. Good luck and have a great winter break. :)

Giselle Simmons 2D

Rewatch the lectures!

Giselle Simmons 2D

Exercise does wonders. Even if you don't have a lot of time, even a short jog or walk can make you feel so much better. Drink a LOT of water. Try to eat healthily so your blood sugar doesn't crash. Make time to be around people that make you happy. :) This reduces my stress the most.

Giselle Simmons 2D

Also- I would say to try and not study in your room. It can get distracting to have roommates and friends coming in and out! The Powell Library puts me in a good studying mood because everyone else there is so focused.

Giselle Simmons 2D

Also, sometimes exercising beforehand clears my mind and makes it easier to study.

Giselle Simmons 2D

My best tips would be caffeine, classical music, turning your notifications OFF, and giving yourself a reward to look forward to when you finish!

Giselle Simmons 2D

I really like handwriting my notes because studies have shown handwritten notes will cement in your memory better!

Giselle Simmons 2D

While studying for midterms, I found it helpful to rewatch lectures. Once I had done some practice with the topic, watching it again helped clear up any questions I had and solidify the concepts.

Giselle Simmons 2D

Thank you so much Ashley best of luck with everything. :)

Giselle Simmons 2D

I like to exercise to calm the jitter! Going for a walk the morning of a big test / waking up early enough so that you're not rushed before always helps :) Good luck, you'll do great! I would also agree that exercising does wonders to ease anxiety. :) Harvard states, "The mental benefits of ae...

If you are nervous, remember how much you have accomplished to get to where you are today- a STEM student at UCLA. :) Based on that, you studied plenty. Now, you just need to believe in your abilities and try your best. Even if it doesn't go as well as you hope, it is NOT the end of the world I prom...

For the other major resonance structure, consider creating a double bond between Nitrogen and Carbon.

Giselle Simmons 2D

Also, try and find a friend who's done AP or IB Chem! They are usually really good at explaining problems you may need help on. :)

You should 100% go to the step up sessions. They saved my grade. Here's the schedule.

Wait, are all these jokes too basic for you? Because I see no reaction.

What was Avogadro's favorite sport? Golf! He always got a mole-in-one!

Why does a hamburger have less energy than steak? Because it's in the ground state!

Old chemists never die. They just stop reacting!

Two chemists walk into a bar. One tells the bartender, "I'll have an H2O." The other says, "I'll have an H2O too!" The second chemist dies.

Kind of dark but oh well.

What are you guys doing over winter break? Also do you have any good book or movie recommendations? I am going to be road tripping down the Pacfic Coastal Highway with my family in an RV (social distancing at its finest). I am super excited to visit a bunch of beaches and escape my house. :) Also, ...

I think I'm going to go skiing in Tahoe with some friends! I might wanna try snowboarding though...

Giselle Simmons 2D

Mine wasn't working either, but for a different reason. It said to remove my Castify extension but I couldn't see it under extensions. Does anyone know how to fix this?

Giselle Simmons 2D

Also, here's the schedule for all the step up sessions and workshops!

For B, I was a bit confused but here is how to do it.
First, convert 150.6 KJ/mol (given) to Joules by multiplying it by 1000L/1 KJ. This should give you 1.506 x 10^5 J.
Then, divide 1.506 x 10^5 J by Avogrado's number, which is 6.02 x 10^23 mol.
The answer is 2.501 x 10^-19 Joules.

Giselle Simmons 2D

For A, how do the units work out to be Joules for the answer?

Giselle Simmons 2D

It would also be good to know E_kinetic(e^-) = hv-E_eject(e^-)

Giselle Simmons 2D

These are so smart thank you all! :)

Giselle Simmons 2D

Is the equation E_n = -hR/n^2 only specific to Hydrogen?

Giselle Simmons 2D

Hi, When converting grams to moles and dividing the grams by an element's atomic mass, is it crucial that we use as many decimal places as given in the periodic table? For example, if we divide 40.9 grams of C by C's atomic mass to find the amount of moles we are dealing with, would we always divide...

I wondering when Joules seconds is used? And how this is different from Joules per second? Thanks.

This article discusses how mercury travels from the atmosphere to the sea and contaminates our food. This is interesting because it is so relevant to California considering how the population consumes so much sea food here. https://www.sciencedaily.com/releases/2021/09/210929124357.htm

I think it is so fascinating that literally everything can relate back to chemistry! Even cooking/baking. I think it’s a great analogy when doing limiting reactant problems to think of them as ingredients for a recipe! A limiting reactant is a great analogy. For example, I used to bake cookies with...

Love this thread! One thing I have recently began to do is add vinegar when I am boiling or poaching eggs. The acid in the vinegar prevents the water from spilling out of the pot if a shell breaks and helps with the coagulation of the egg whites. Emily- That's such a cool tip I had never heard of! ...

I always thought the chemistry behind baking bread and having it rise was super interesting. Yeast in an ingredient of bread, which is a single-celled fungi which helps to convert sugars in the bread mix into carbon dioxide. Bubbles from the carbon dioxide are what cause the bread to physically rise.

This is not necessarily involved with cooking, but it applies to the kitchen! I always remember when my family cleaned the kitchen with bleach, my mom would warn us not to put the bleach next to the ammonia in the cleaning supply closet. This is because when combined, bleach and ammonia release toxi...
