This is a very basic answer but sweets-wise, I love Lindor chocolates and Ferero Rocher.... I also love love LOVE pizookies! For like... REAL food I would have to go with an undeniable go-to - Pizza!

I am looking forward to meeting all the friends I've made online, in person and feel what college life is really like! I want to study together, and experience normal college things together with other people!

Your post from the 21st will count towards Week 7!

Burnout normally hits me when I get a lot of deadlines at once. Normally the satisfaction of finishing my assignments satisfies my burnout but if that doesnt work I rough out all my work and then just sleep. As much. as. possible!

Devan Nathu - 2H

i LOVE LOVE LOVE ice cream, and pizza.. as basic of an answer this is you just CANNOT go wrong!

ANYTHING by 6lack or Eli Sostre! Straight up VIBES.

Devan Nathu - 2H

Definitely going to skim through the lectures and try to do textbook problems without help as much as I can! Doing problems helps me most so I will probably prioritize that.

Devan Nathu - 2H

I think starting at 13 to the end (20), we will be reviewing this week!

Devan Nathu - 2H

I'm looking forward to go INSIDE the beautiful UCLA buildings! Also to meet new people. ALMOST THERE! MANIFESTING IT!

Devan Nathu - 2H

I ALSO had this glitch, refreshing the page a few times did not help me so I logged out, and didn't touch my laptop for a few hours. Came back and it was perfectly fine. Hope it all worked out okay for you!

salt bridges are simply there to prevent ions from accumulating. This helps with neutrality.

I surprisingly did very well on this midterm compared to midterm 1. After midterm 1, my chances at an A in this class kinda went downhill but I think if I do well on the final, I could manage a B+! As long as it's better than a B-. Midterm 2 had more time than midterm 1 and that was SO helpful I'm n...

Harry Potter, of course! I am still a tad bit surprised there are a lot of people who haven't read Harry Potter. Also, i LOVE the DaVinci code series. That is my favorite series of all time literally anything by Dan Brown will blow you away but then again I love mystery!

Devan Nathu - 2H

I've been rewatching iCarly to get ready for the reboot! I love watching shows from my childhood like Drake and Josh, Hannah Montana, iCarly, etc... As far as favorite movie. I love mystery thrillers like Deja Vu (Denzel Washington), or the Da Vinci Code Series. gotta love Tom Hanks! <3

Devan Nathu - 2H

Yeah, of course! I sadly do not have all of my points... I am trying my best to make them up. I was under the impression that i could post whenever I wanted this quarter but I needed to have 50 by the end of the quarter but apparently they are counted every Sunday so I do indeed have some serious ma...

Devan Nathu - 2H

I think just re-familiarizing yourself with the material will go a long way. They won't just throw you into material and expect you to know everything off the bat, but that doesn't mean you may not feel flustered at first. I think even glancing over your previous chemistry notes from high school wou...

The only thing I am apart of for UCLA is a bollywood fusion dance team called, "UCLA NASHAA". I would love to expand my horizons, but I LOVE being on this team!

Devan Nathu - 2H

I think I am going to focus mainly on knowing how to solve problems from Sapling. I will cover up the solutions and continue to try to solve them until I can do them successfully. I think the week before I will also start rewatching the lectures. Discussion sections do help a lot though! Special sho...

Devan Nathu - 2H

I don't think the order matters, but someone please correct me if I am wrong! Sorry I couldn't be of much help.

Devan Nathu - 2H

What is "HIJKLMNO"?
- H2O.

This one lowkey gets me all the time.

Devan Nathu - 2H

Yes, this is the same for me it will probably fix itself don't worry too much about it though ahah not to be a vibe killer buttttttt MIDTERM SOON! :,(

Devan Nathu - 2H

I hope you all enjoy your long weekends! Midterm soon don't stress out too much I'm sure you all will do amazing!

Devan Nathu - 2H

Queen's Gambit was VERY good i must admit that was a one day binge! I am a very big fan of Grey's Anatomy and The Flash though... Call me basic... :)

Devan Nathu - 2H

I am not sure but I am lowkey nervous, anybody with me? What are you guys struggling with the most?

Devan Nathu - 2H

Entropy is J/K i believe, not sure if this answers your question!

Devan Nathu - 2H

I always forget coefficients in chemistry because I am going too fast. Talking myself through the problem as I go really helps me.

Devan Nathu - 2H

I think it all depends on the problem you're given. You will just have to adjust your units given what you have and what you need and make that adjustment for each problem!

Devan Nathu - 2H

This was actually one of the most helpful posts I've seen on chem community to date, thank you!

Devan Nathu - 2H

Energy cannot be created or destroyed! The one part of the laws of energy I will always remember!

Devan Nathu - 2H

I think it is theoretical, because i don't think there is such thing as a PERFECT heat engine in the real world. I may be wrong though!

Devan Nathu - 2H

Not personally a fan of Kdrama, but seeing all these suggestions makes me lowkey want to look into one loll

Devan Nathu - 2H

Definitely not holding back on classes in anticipation for Fall quarter. Not saying it won't happen or that it's unlikely but I am just going to continue along my normal class course and take whatever class I need to following this class! MY enrollment period is so late though!

Devan Nathu - 2H

Congrats everyone! I get so stressed for chem exams but hey! ITS OVER! Until the next one... tee hee. But yeah great job guys!

Devan Nathu - 2H

I believe my TA mentioned that it was a strong acid!

Devan Nathu - 2H

I have this ability to get messed up by questions even when I feel prepared and that exact situation happened. I got into the exam and the questions were just like... interesting to say the least haha. But oh well i guess! Onto the next one!

Devan Nathu - 2H

I tend to procrastinate but when I actually study ;)... I like to go over slides and practice problems when they're available! This helps me the most!

Devan Nathu - 2H

I personally have not read the textbook but my TA goes over textbook problems in discussion, so I honestly might start skimming and taking selective notes over it. If you have time, it definitely wouldnt be a bad idea to review the textbook!

Devan Nathu - 2H

I actually had this same question haha thank you for asking! I tend to cram so my advice isn't the best and seldom works, but some of these study tips people are saying sound like great options! WIll definitely try them out!

Devan Nathu - 2H

Definitely do a brief review! Professors do make sure you get the gist of it again before you do assignments and whatnot, they don't just throw you in. Also there are plenty of opportunities for questions not only through chemistry community, but through office hours and discussions as well! So don'...

Devan Nathu - 2H

I'm big into Rap and Ambient Rnb, late night drive music. EscapeTracks on Youtube post nothing but quality music! Also, I'm a huge Bollywood nerd haha so that's actually the majority of what I listen to.

pKa is the -log of the acidity constant (Ka).

Devan Nathu - 2H

Sapling randomizes the numbers for each person, the overall solution however, should be the same.

Devan Nathu - 2H

The Kw value at 25C is 1.0 x 10^-14. It is also the designated value for Kw. Because water is neutral, it can be inferred that the [H3O+] and [OH-] concentration will equate to each other and have the same value, which is where 1.0 x. 10^-7 came from.

Devan Nathu - 2H

Yes! The Kw value will change based off of the temperature, which in turn changes the pH of a solution. Water is considered neutral when the acid and base concentrations are the same, hence pH = 7.

Devan Nathu - 2H

Yes, you always have to translate the coefficient into the exponential value in equilibrium concentrations.

Devan Nathu - 2H

Since the system is being compressed, which applies to pressure, we are only looking at moles of gas. Therefore, since there are 6 moles of gas on either side of the equation, the system would not favor either side when compressed. Why don't you take the six moles of gaseous water into account on t...

Devan Nathu - 2H

The general rule of thumb is to never take into account the liquids and solids, only aqueous compounds, because liquids and solids are incompressible and their concentration stays constant throughout the reaction. The concentration value of liquids and solids is so high that including them in the eq...

Devan Nathu - 2H

For pure solid and pure liquid, active mass is taken to be unity, i.e., 1 as they remain constant throughout the reaction. In other words, pure liquids and solids are made up of one substance, hence they do not have a concentration because it doesn't change enough.

Devan Nathu - 2H

Yes it can! However, Kc should be used if all of the species in the equation are aqueous, you should be using Kc. When everything in equation is gases, either Kp or Kc can be used.

Devan Nathu - 2H

Where does the value for the gas constant come from? I understand that the value equals 8.3144598 J/mol·K, however how was this value calculated?

Devan Nathu - 2H

Just to clarify, will we always be able to assume that the reaction is at equilibrium when K=Q? Thanks!!
