AP Chem - Unit 7 Review - Equilibrium in 10 Minutes - 2023

[@evanfaimon6281]

Equilibrium has so much more content than I remembered! I'm cramming currently studying for the AP Exam, I really appreciate your videos.

[@JeremyKrug]

Equilibrium is definitely a big idea in AP Chem, and it extends to other units as well. Thanks for watching!

[@patrickadaoperez5452]

Actually crying and throwing up cus I got a 3/33 on the MCQ for this unit❤

How was the exam?

[@evanfaimon6281]

@@jenpuff I ended up getting a 4, almost entirely because of this page tbh. Are you taking the AP Chem test?

[@shahda4803]

My exam is 6 hours and I am literally just learning the content now. THANK YOU

[@JeremyKrug]

Glad I could be of help!

I just wanna say Thank you! These ap videos helped me feel confident about my test and you really condensed so much information into a quick overview that's somehow still extremely informative :3

[@JeremyKrug]

I'm really happy my videos helped you out. I'm hoping you got a great score today!

[@AdiR9234]

@@JeremyKrug Hi Mr.Krug, Thanks so much for the review! It really helps! Since we're getting closer to the AP exam, could you review practice FRQs on your channel? If you need it, I can send you some :D

[@Elustria]

My unit 7 test is in a day and after watching your videos + practicing some questions i feel pretty confident 😌

[@JeremyKrug]

I'm glad to hear that. I hope you did great on your test, and all the rest you have coming up!

[@abdullahp6248]

Exam in 2.5 hours away. Thank you for making all these videos that I can watch for a quick refresher on everything before the exam.

[@JeremyKrug]

You're very welcome. Hoping the exam goes well for you today!

[@MMohamed-ow2bo]

Thank you a lot for this wonderful explanation

[@JeremyKrug]

You're very welcome. Equilibrium can be one of the tougher sections on AP, so I hope this video helps a lot of students.

[@AndrewMS.]

Thanks for this review!

[@JeremyKrug]

You're welcome, Andrew. Best wishes on your exam Monday!

[@bookdragon7546]

This is so helpful! Thank you so much! I feel so much more ready for my exam today!

[@JeremyKrug]

I'm so glad my video was helpful to you. You're going to do great today!

the exam is today, i am hecked.

[@sony8848]

That pacman tip is such a lifesaver. I really appreciate the time and effort you are putting into these review videos and how much content is in just 10 minutes. Thank you very much! :)

[@JeremyKrug]

Glad you liked the pacman tip. I came up with that a couple years ago and was hoping that would help. Thank you for watching, and you will do great on your exam tomorrow!

[@2b2c1d2]

​@@JeremyKrug is it always going to be Q>K or can it also be K>Q on the AP test?

[@OmeQR]

You literally carried me through my studies, just like Mr Sinn did for AP Human. I can't thank you enough

[@dharunnaga]

Thank you so much for the simple explanations!

You're very welcome. Thanks for the kind words!

Thanks for watching, and keep up the good work in chemistry!

[@ryanellis9239]

Currently very nervous but these videos certainly help.

[@JeremyKrug]

No need to be nervous, Ryan. If you've been studying and working all year, you will do GREAT today!

ap exam tomorrow thank you

[@JeremyKrug]

Tomorrow's going to be a GREAT day for you! You've got this!

[@2b2c1d2]

at 9:22, are you sure we can just take out 2x from (0.1+2x)^2? because when I tried calculating it, I got about −0.0509, far from 6.6 * 10^-4. i hope I didn't do anything wrong.

[@JeremyKrug]

The 2x is very small compared to the 0.10, small enough that we can ignore it in the equation. That's confirmed by looking at the answer, which is 6.6 x 10^-4 (way less than 5% of 0.10).

[@thanosasscheeks]

In 2:58 if k is large, the reaction will shift to the left, right? Since products are larger.

[@JeremyKrug]

If K is a large value, equilibrium will favor the right side, which means we should have higher concentrations of products than reactants at equilibrium. Great question!

[@thanosasscheeks]

Thank you so much!!

[@Cerumiri]

thank you mr krug!! 🥳

[@JeremyKrug]

You're very welcome!

[@带安安]

I have a question, at 9:52 of the unit 7 vedio, why the weak base is the conjugate base of the weak acid? but you have said in early vedio, the stronger acid it is the weaker conjugate base it have.

[@JeremyKrug]

Remember that there are only 8 strong bases and 6 weak acids, so any other acid or base will be weak. Pretty much any weak acid will have a conjugate base that's also weak. We can see HOW weak it will be by looking at its Ka value. Also remember that the Ka of any weak acid times the Kb of its conjugate base will equal Kw. I hope this helps!

[@带安安]

@@JeremyKrug So except 8 strong base and 6 strong acid, all others are weak, but i means you have said the weaker acid have stronger cnjugate base, like F- and CO3 2- actually are strong conjuate base, and the weak conugate base is hardly to react with the acidic solution.

[@krispy9038]

In this test i should do good this test is only for equilibrium since its before winter break, so i dont har to take anything for scid and bases

[@JeremyKrug]

Sounds good. Acids and bases will be Unit 8, I'm working on getting those videos finished over the next week or so.

[@hayleymikealson5551]

How did u get you 6/10 ? I know where the 10 came from but the 6??

[@Ricky-jj6ot]

There are 6 hydrogen molecules out of the 10 total molecules.

Thanks🎉🎉

[@JeremyKrug]

You're welcome!

[@notadam7867]

i got a 20 on my test. feeling fabulous!!!!! help me

[@JeremyKrug]

Focus on the individual lessons instead of the big review. Go back to the "AP Chem full playlist" and watch the individual lessons for the unit you need help on. It will take longer than 10 minutes, but the time investment will be worth it. You can do this!

[@linkanika]

woahhhhhhhhh

[@JeremyKrug]

There’s a lot in these 10 minutes!

[@Sushimindest24]

I have my exam after an hour am dead 💀

[@sunilsandhu7863]

[@FrenchFries879]

I really dont understand the part where you put variables like x or -2x when you determine the concentration for all substances at equilibrium. Ive watched your videos about it 3 times to no avail. In the end i just skipped the thing entirely :( 🥲😭
