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

[shahda]

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

[ringcat]

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

[Elustria]

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

[abdullahp]

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.

[sony]

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! :)

[OmeQR]

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

[MMohamed-owbo]

Thank you a lot for this wonderful explanation

[jaronharris]

In 5:42, how did you know the mole fraction was six out of 10? It is because it had six total H2 molecules, and if so, why did it have to be out of 10? Is it because of the 4 hydrogens on the CH3OH?

[bookdragon]

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

[archmusical]

Amazing videos! Learned lots from them and they even leaked some exam questions. Hoping for a 5 on the ap test in May.

[kaidoust]

Jeremy Krug thank you so incredibly much!

[dharunnaga]

Thank you so much for the simple explanations!

[bcd]

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.

[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.

[thanosasscheeks]

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

[elise.who.has.problems]

My teacher wasn't joking when she said equilibrium is easy but complicated. Gonna be a rough exam but at least I get some of it

[krispy]

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

[hayleymikealson]

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

[Mitsuayagoat]

i got a 20 on my test. feeling
