ENDGAME Review Session

[Chem_Mod]

The title is called "ENDGAME" so that you can search "ENDGAME" and easily find this post!

We're in the endgame now. This is your graduating UA, Lyndon Bui, ready for my last ever UA session after three years of service. I am happy to present my packet of questions on Electrochem and Kinetics, since other topics were covered during the midterm review session.


Please complete these problems before my review session. My review session this quarter (W20) will be Friday, March 13, 6-9pm, in Moore 100.
I will go over each problem in detail during my review session. The answers, but not full solutions or work, will be posted here at this post after the review session. Any errors in the test will be posted below as well.

Happy Studying and Good Luck! I love you 3000
-Lyndon Bui, UA

Hello everyone, thank you for your kind words. I was looking forward to this review session, but unfortunately it will have to be cancelled. Judging from Dr. Lavelle's email, I am sure you all will do well on the final, and I wish you the best with all of your future endeavors. Good luck, and have a wonderful and safe Spring Break!!

-Lyndon Bui

[Sally Qiu 2E]

WE LOVE YOU 3000 TOO LYNDON

[Annie Chantasirivisal_4G]

Thank you for all of your hard work these past three years, Lyndon!! King of chemistry congrats on graduating we'll all miss u dearly <3333

[Kaitlyn Ang 1J]

Thank you Lyndon for putting so much time into us. I’m not alone in saying that your weekly workshops, your packets, and your review sessions are probably the only reason I passed 14A and (hopefully!) pass 14B.





P.S. Endgame is a suitable name for replacing Gummy Worms

[Brian J Cheng 1I]

We cannot thank you enough for your service Lyndon! Thanks for making Chemistry something we can enjoy, and for making your review sessions something we could all look forward every quarter! Love you 3000 king

[vibha gurunathan 1h]

Thank you so much for creating this!!

[Michelle N - 2C]

Thank you for everything you've done Lyndon! We truly appreciate it!

[Abigail Sanders 1E]

Will this review session still be held now that all classes are cancelled? Lyndon's sessions are normally the most helpful thing before the finals/midterms.

[Prasanna Padmanabham 4I]

Thank you so much Lyndon! I appreciate all the time you have put into us even though you had a really busy schedule with upperdivs and other commitments.

Facts! If not hosted in person, maybe livestreamed...?

I will actually fail this test if this session gets cancelled :(

[alex_4l]

Thank you so much :')

[Robert Tran 1B]

Will there be a livestream option for the review session with classes being cancelled?

[AArmellini_1I]

Thank you so much for all your help! I know it may be a lot to ask but I really would appreciate it if you could livestream or record a review session. They help me so much for the exam

[Jarrett Peyrefitte 2K]

Thank you King Lyndon you da best :)

[Deena Doan 2F]

thank you Lyndon for your service and help!!! i was wondering if there is any way you could do a live stream or Zoom this session.

[Ghadir Seder 1G]

Can there please be a livestream for this review session that can be posted for reference after as well? This is absolutely the most helpful thing :(

[Trent Yamamoto 2J]

Since classes are canceled, will the session still be happening or is it going to be recorded on zoom/bruincast/an online alternative?

[Brandi 2C]

Thank you SO MUCH for gracing us with your review sessions even though you aren't being mandated nor paid to do so!!! I think I speak for everyone when I say I love you 3000 x 3000 x 3000 x 3000!!!

Also... will this review still be going on regarding the recent notification by Gene Block that classes will be cancelled?? I'm speaking in regards to the "all nonessential gatherings of 100+ people will be cancelled" statement that he said in the recent email. Don't get me wrong, I do believe this review session is ESSENTIAL but I am still curious about what is going on regarding the finals and reviews going forward.

[Jaci Glassick 2G]

THANK YOU SO SO SO SO MUCH FOR THIS WORKSHEET AND BEING SUCH AN ATTENTIVE UA FOR THESE PAST TWO QUARTER!!!!
That said, is the Friday review still happening? If so, how's that going to work?

[ShastaB4C]

You are literally the only reason I made it through 14A/B lol. Thank you soooo much

[Philip]

Are we still going to have a review session on Friday?

[Yailin Romo 4G]

Is this review session going to be live streamed??

[Maya Beal Dis 1D]

Are all review sessions going to be cancelled?

[Kevin Antony 2B]

Are all review sessions going to be cancelled?

I'm pretty sure they all will be cancelled.

[Jamie Hwang 2F]

I really hope this is still happening some way and if it doesn't, that sucks because it's Lyndon's last one.

[Veronica_Lubera_2A]

Thank you Lyndon so much for your kindness and compassion when teaching chem 14A/B to us!! We didn't know it at the time, but we were all looking for someone to relate difficult concepts and share funny jokes during workshops. Keep working hard and we will always support you!

[Chem_Mod]

Hello everyone, thank you for your kind words. I was looking forward to this review session, but unfortunately it will have to be cancelled. Judging from Dr. Lavelle's email, I am sure you all will do well on the final, and I wish you the best with all of your future endeavors. Good luck, and have a wonderful and safe Spring Break!!

Thank you Lyndon!
Will you still be able to post answers to the review so that we can check our work if we already completed it?

[Madeline Phan 1E]

Thank you for being such an incredible, patient, and dedicated UA. I wouldn't have understood most of the topics we went through in class without your help. Thank you again for spending your free time helping freshmen navigate general chemistry. Good luck with the rest of your adventures!

[JChen_2I]

Thank you for all your help these past two quarters, Lyndon! Thank you for putting in so much time and effort to get us through these courses. Congratulations on graduating and best of luck in the future!

[Lindsey Chheng 1E]

Hi Lyndon! I'm Johnson's friend, the one from UKS at APIDA Night Market! Thank you for all your help this quarter, you're a big inspiration for the rest of us. I really appreciate all the time you dedicated to help us learn and grow these past two quarters. Good luck with everything, I wish you the best! Stay safe from the virus :)

[alex_4l]

Are the answers to this still going to be posted?

[Sebastian Lee 1L]

Thank you Lyndon for all of the work, time, and dedication you have done in helping all of us learn, succeed, and grow in these past two quarters. You have been an absolutely wonderful, smart, and fun UA and your review sessions have helped all of us improve our understanding and skills.

Thank you so much for everything Lyndon! You've been such a great UA and helped everyone so much throughout both Chem 14A and 14B. We really appreciate all the time you have put in to helping us students succeed. Good luck with your future endeavors after college as well!

[Izzie Capra 2E]

Thank you Lyndon! I honestly couldn't have done this class without you! You will be missed.

[Sanjana Munagala_1j]

Thanks again Lyndon! Like everyone has already said you have been very helpful and a part of the reason for why I have been doing well in chemistry. I hope your future endeavors go very well for you, as I am sure they will. Good luck for you and your future! Thanks again!

[Rebecca Remple 1C]

Hey Lyndon! Thank you so much for all of your hard work this quarter. I've been using your worksheets to study since 14A and they are so helpful. You've put so much work into everything you do and I really appreciate it. I'm sad to see that the session is cancelled but I will definitely be using your worksheet to prepare. Thank you again for all of your help and good luck in all of your future endeavors! :)

-Rebecca

[Naren_Ramesh_4F]

Thank you so much Lyndon! Without your review sessions and your great worksheets, Chemistry 14A and B would have been so much worse. Because of the nature of the cancellations, will there be an answer key that will be posted?

[Tiffany_Chen 2K]

Thank you for an awesome two quarters! Best of luck in your future endeavors :)

[Christine Honda 2I]

Thank you so much, Lyndon! Thank you for your dedication, patience, compassion, and hard work. I've been going to your workshops every week since 14A and I honestly could not have passed this class without you! Good luck in your future endeavors!

[Philip]

When are the answers going to be posted?

[vibha gurunathan 1h]

Thanks so much Lyndon! Your review sessions and worksheets were incredibly helpful!

[Gabriella Bates 2L]

Lyndon thank you for putting so much effort into every review session and being a terrific UA! I've been going to your sessions since chem 14A and you've been so helpful. I wouldn't have passed without you. I wish you all the best!

[Kallista McCarty 1C]

Are the answers for this worksheet going to be posted soon?

[Maggie Eberhardt - 2H]

I love you

[Tiffany Chao 2H]

Thank you so much for all your hard work Lyndon! You have helped us tremendously and I can't thank you enough. Best of luck to you!

[Jialun Chen 4F]

Thank you Lyndon!

[Clara Cho 2K]

Will the answers to ENDGAME be posted soon?

[nehashetty_2G]

Thank you for everything Lyndon!!!

[Kevin Antony 2B]

Thanks for all the review sessions that have helped us along the 14 series!

[ramiro_romero]

Thank you for everything and congratulations! Is there a specific time when we should expect the solutions?

[Chem_Mod]

You may expect answers to be posted now

[ayushibanerjee06]

For #2, I used the E=Eo - (0.05196/n)logQ equation and got 1.7x10^-6 M. Did anyone else get this?

[ayushibanerjee06]

For 5, why is the first SRP flipped? Shouldn't it be the cathode because it is the more positively charged one?

[Chem_Mod]

For 5, why is the first SRP flipped? Shouldn't it be the cathode because it is the more positively charged one?

Good Question. Because of the context of the problem, we needed an equation that had HF as a reactant, dissociating. This is how we can eventually get a Ka. Because of this, we used the equations in a way that kept HF on the reactant side.

[Luyan Zhang - 2D]

For number 7, when you flip the second one around, the E value becomes negative. Do you use this negative E value to calculate G? I thought you would still use the standard reduction potential.

[Sebastian Lee 1L]

For 1E, I thought increasing the concentration of Ag+ on the cathode side would increase the cell potential. In the Nernst equation for a concentration cell where Q=[anode]/[cathode], increasing the cathode concentration will decrease Q which makes the term more negative which means a more positive E cell right?

[Jared Khoo 1G]

Usually, aren't E* values by default given for reduction?

[Chem_Mod]

For 1E, I thought increasing the concentration of Ag+ on the cathode side would increase the cell potential. In the Nernst equation for a concentration cell where Q=[anode]/[cathode], increasing the cathode concentration will decrease Q which makes the term more negative which means a more positive E cell right?

The wording of the question is a little tricky. The substance added precipitates Ag+, which means that it removes Ag+ ions from solution and turns it into Ag (s). This would decrease the concentration of Ag+ at the cathode.

[Jiyoon_Hwang_2I]

Can someone explain why E=0 for question 5?

[chimerila]

Seriously so helpful, Lyndon for the win

[Emily Burghart 1k]

You're great! thank you for posting a comprehensive answer key despite not being able to have the review session!!

Your sessions were very helpful!

[Ghadir Seder 1G]

How do you know which equation to flip when the electrons are on the same side?

[CNourian2H]

This was very helpful, thank you!

[CNourian2H]

I was just confused on 14f if anyone can explain it.

[DesireBrown1J]

Thank you for all your help in chemistry 14A and B. I really appreciate all the hard work you put into making the worksheets and review sessions. They were really helpful.

[Jessica Castellanos]

Thank you so much for all your help for the past two quarters :)

[Anushka Chauhan2B]

Thank you!

[Ivan Tadeja 1G]

Thanks for all your help Lyndon. Your review packets have been such a big help through this series. I wish you the best of luck in all your future endeavors.
