Good luck on the exam, guys! You're smarter than you think you are! Go get it!
Everyone pause !!!! Jeremy krug just dropped another chem banger
Thanks for the shoutout! I've got an even bigger one coming up later this week, still recording and editing.
@@JeremyKrug youre the best!
I’ve always struggled on the MCQ. I got a 61 on a practice MCQ while I got a 73 on a practice FRQ.
My teacher thought I was cheating because of how different the scores were lmao.
Thanks for making the video, this is gonna save me in my mcq tomorrow :D
The easiest way to remember that paper is the stationary phase is that paper is stationery
Thank you so much for your videos. They are very helpful. I’m taking this exam on May 6th and this is a good refresher after covering so much material all year. Keep doing what you’re doing because it’s helping the people that want to succeed.
Im so excited for the Frq review 🥳
Thank you Mr Krug!! this video helped me a lot!
I'm glad this video helped you out!
Last minute studying, thanks boss!
Love your videos!! You explain each concept really well and I really appreciate these videos
Thanks for your kind words. Reading comments like yours motivates me to keep making videos. Best wishes on the exam Monday!
I really appreciate the videos, preparing myself for the exam.
I'm so glad these videos have been helpful for you, thanks for watching!
Jeremy, you’re an absolute legend. You’ve got me well prepared for this test 🔥
Thanks so much, I'm so proud of you for being so well prepared. You're going to do great on Monday!
@@JeremyKrug Just took the test and I feel really good about it! Thank you again for everything, I’ll be sure to recommend the students taking it next year about this.
Thank you!! Please drop another mcq video like this, I had no idea the mcq was this hard..
The MCQ has a wide variety of questions. Some are easier than this, but I wanted to go over some of the more challenging questions out there.
How do you know when to use stoichiometry vs ice boxes (equilibrium tables)?
pls make more of these before the exam!!!
Mr. Krug thank you my man! 🙏
You're very welcome. Thanks for watching!
Thank you!!
You're welcome!
The exam is on may-6 😔💔
Just a week away!
Unfortunately, like seriously how fast 😭 @@JeremyKrug
@@ghassanqattan9832 2 days...
Good luck guys
@@Thang-fz7wbthanks you too😊
Jeremy is legitimately saving lives with these videos
I hope I'm saving some grades and AP scores, too. Thanks for watching!
guys wake up mr krug is about to help us get a 5 on the ap examm!
AMAZING!!!!
Glad you like it!
Thank u Mr. Krug! any tips on where we can go to find additional MCQ practice questions that look like what's going to be on test day?
I have had significant success with AP Classroom in other courses and we've been working in it all year for AP Chemistry. Personally, I have found those problems to be helpful. The videos are not usually as good and I prefer independent creators (like Mr. Krug) so much more.
Like @garsh5453 said below, AP Classroom has lots of MCQ practice. Other than that, CB doesn't like to release a lot of those old MCQ questions, since they tend to recycle those questions a little more.
please exam in 4 days, the questions arent stating to which significant figures i must round, im lost
Thank you for this review. Could you possibly make an FRQ review as well?
I have lots of FRQ walkthroughs from the last few years, and I have a big cram session video coming up later this week. I hope that helps!

HI! Quick Question - Do your videos cover everything that the Collegeboard curriculum teaches? They do not miss out on anything, right? In my class, we have not even finished covering unit 9 (Applications of Thermodynamics), and have found myself stressing over this exam. My goal is to get a 5, but I am scared because of what I have said earlier, and need to get studying. Please assist in any way that you can.
Yes, I try to cover the entire AP Curriculum in my complete course playlist. There are 101 videos that cover all 91 topics in the course.
For question 13, how do you know that it is a redox reaction?
Thank you for making these videos they help me out alot, Frq review pls if you have the time!!!!
Here's an FRQ walkthrough from last year, if this helps:

We love you Jeremy Krug!!!
Thanks so much!
THANK YOU KING 🙌🙌
You're very welcome. Thanks for watching!
Quick question @JeremyKrug, in question number 13 it does not specifically ask for a net ionic equation, so how are we supposed to identify that it is asking for that instead of the general equation? Is it because it specifies to identify the "reacting species"? Thank you for the help as always!
The question mentions "reacting species" instead of net ionic equation. Now, the definition of net ionic equation is: a chemical equation at only shows reacting species, and that's how you know which one they are asking for.
If it says "reacting species" or anything like "net ionic equation", you'll write the net ionic.
I’m so cooked 😭
wishing the best for u bro😭😭😭
You've still got time to do this, don't give up!
I am more nervous for the MCQ than the FRQ! I think a key component of a lot of these problems is writing out an equilibrium expression just to make sure I don't get lost. Are you going to do more MCQ practice?
Tyler DeWitt has lengthy videos with many MCQ walk-throughs. I strongly suggest you to check them out.
Petition to publish more videos like that!❤
I have a big cram session video coming up later this week. Stay tuned, and thanks for watching!
@@JeremyKrug life-saver!!!!
@@JeremyKrug OH MY GOD I LOVE YOU
@@JeremyKrug WHEN???
You're a real GOAT
Thanks so much!
Thankyou for the video, so on question 8 can you please explain why the concentration of NH3 is still greater than [Ag(NH3)2] even though the Keq constant is greater than 1? I thought for keq if it is greater than 1 that entails that the reaction is moving forward and the concentration of the products would be greater than the concentration of the reactants. Thankyou
Hi! So for this one I had the same question, but i think it's because of the Keq value. Since it's so large it would mean that there's more products than reactants like you said, however, I don't think we think of it that like that, but rather to what extent the reaction will continue to completion. Since it's so large, we need to say that it will almost react to completion, so you just use a ice table to do stoichiometry and then solve.
Hi! I am US student who has exam on may 6th and have a little question
I have been doing frq section and got struggle with sig fig
Is this really matter on the exam???
Because problem says 0.300g at first and next sentence says 138.12g I don’t know which one should pick as my sig fig number 3 or 5???
If I am not sure about this can I just use 3 sigfig?? And for PH is it always 3 sigfig??
Thank you love ur video😻😻
I think that for regular sig figs, you round it off to the least amount given to the problem. In this case, you will round your final answer to 3 sig figs. For pH calculations, the total number of sig figs in your concentration of [H+] is the number of decimal places that your pH has (same thing for pOH). For example, if I have a [H+] of 1.0 x 10^-14, my pH would be 14.00. I hope that answers your question (all of this is answered according to my chemistry instructor who has taught AP Chemistry for many years).
hello mr krug, so on question 13 when you said that cl anions are spectator ions how do we know that because i dont remeber my teacher telling us that anions form strong acids enters and leaves the equation without binding to another molecule.
Strong acids always ionize completely, so the Cl- enters the reaction in ionic form. Since metals react with cations in redox reactions, the chloride has nothing else to react with, so it will be a spectator ion.
@@JeremyKrug thanks alot!!
@@aishamohamed5106 Remember, a metal reacts with a metal ion (along with hydrogen)! Those anions will be spectators in this case.
@@aishamohamed5106 If an anion and an ionic compound were reacting, the anions would react because anions react with other anions. The cation will be a spectator in this case.
Why couldn't we do a calculation for question 9?
Oh, boy. Twenty minutes before I gotta be at the door for the exam.
I have a question. How do you explain how Kw changes as temperature varies using Le Chatelier's Principle? I kinda understand it but I need someone to really write it down for me
You have to see heat as prouduct or reactant. For example, heat is reactant when a reaction is endothermic. Thus if you add more heat to that reaction the equilibrium will shift towards the products. On the other hand, if a reaction is exothermic heat is a product. Therefore, if you add more heat (adding more product), the equilibrium will shift towards the reactant. Hope that helps and good luck if you are taking AP chem test on 6👍; I am also taking it this year
@@mohammadshazidislam612 thank you! good luck to u too!
so these style of questions will 100% come on the exam?
also can you do more please of the mcqs as i mess up on them more occasionally
No one (except for the test development team) knows for sure what style of questions will be on the exam. We know that they will cover the entire course and will have a wide range of difficulty. Study the best you can, and you will be in good shape!
The absolute GOAT
Thanks!
Mr. Jeremy,
Do you have any predicted questions for this year’s exam?
Not exactly, because when I try to predict what they'll ask, I'm usually wrong. Your best bet is just to be prepared for anything CB might throw at you.
Can u pls do frqs 2021 and 2020😢❤ and ur the best
Wait i have a question about 8, wouldnt u have to take in consideration that the large K value means that at equilibrium there would be much more products than reactants? So it would then be only A or B
Look at the stoichoimetry of the quantities present. There's simply not enough reactants present to product more of the product than NH3.
Thank you so much for this I have my multiple choice test Tuesday are u gonna do any more videos like this
do we go to the smae school ? lol cuz I have a mcq test tuesday
@@NaturalLog1probably not lol
@@NaturalLog1 I have my frq tomorrow though 😭
I have lots of FRQ walkthroughs from the past few years on my channel, and I'm working on a big cram session video for later this week. I hope these help!
@@JeremyKrug can you have more mcq walk throughs because I think they got harder over the past 2 years the Frqs seem much easier.
Hi Mr Krug, is it possible for you to do some live review in the days before the AP exam?
I'm planning a cram session for later in the week. It won't be live, but it will cover all nine units. It will be dropping later this week and will last about an hour and a half.
@JeremyKrug Thank you! Also I forgot to ask but when we do our math should we use sig figs throughout our entire process and round it to the proper amount of sig figs or should we just round to 3 sig figs?
this is the only time I'm grateful that my teacher gave us 60 collegeboard mcq and 7 question frq tests for every unit 🙏 I feel prepared even though my grade in the class sucks😍
Your teacher cares about you and your AP score. That's a good thing!
Can you re explain 9.? I get that decreasing volume goes to the side with fewer mols, but doesn’t that mean there’s more product? What do you mean, less space less pressure?
omg I have the same question, I'm so lost on that one too 😭😭
let me know if you figure it out!
Since we're shifting equilibrium toward the product side (by decreasing the volume), we'll have fewer moles of gas produced than we originally had. Fewer moles implies less pressure than the 2 atm we would have had if there had been no reaction at all.
Amazing videos we need a free responce questions version
Here is a link to the first question in my 2023 FRQ walkthrough series. Thanks for watching!

Guys wake up Jeremy Krung posted another chem banger!!
And there's another big one coming up later this week...
i wish i found your channel sooner !
Better late than never. Thanks for watching!
Mr. Krug the exam is in 6 days, how should I study??
Here's a video with lots of study tips for AP Chem:
ua-cam.com/video/BIQqLntRUfY/v-deo.html
I thought the question 8 would be a. Because of the high k value, may you please explain that.
I thought the same, so many times when the value of K given, I solve it in a way that a would be the correct answer
Even if the reaction went all the way to completion, the NH3 is in excess, so much so that NH3 will be even more abundant that the product that could be formed. The ICE box shows the relative concentrations at equilibrium. NH3 has to be more abundant than the product.
Isn’t Mg(OH)2 a weak base?
Yes, but in an acid-base titration, moles of acid = moles of base at the equivalence point. As long as one of the components is strong, the acid and base will both react in a 1:1 mole ratio.
@@JeremyKrugOhh okay, thank you!
Today I got a 60% on a mock exam and my teacher said I got an AP 3. I feel like that's gotta be not accurate. I'm soooo nervous for Monday guys
A score of 60% is right on the bubble between a 3 and 4, most years. Keep working, and you're going to do great!
I need to go to sleep- the test is in like 13 hours
We're cooked
nice review questions, Mr.Krug😂😂 mcq requring high understand on what we learned, which cooks my brain😢
I hope the cooking makes your brain stronger. You've got this!
@@JeremyKrug yessss, after reviewed your brain steps on this mcq practice, amount of my correct answer increasing from 50 to at least 70 more, thanks Mr!!! So helpful! If you can, please post more!
Jeremy Krug you are my king, if you see this , save us from this ap exam and bless us with a 5
You're going to have that AP Chem exam for lunch on Monday. Now go out there and get that 5!
For #8 why is AgNH3 not the highest if k>1
I think because the Ag was a limiting reactant, since the reactants were not present in stoichiometric initial concentrations. So that’s why the all the Ag reacts approximately due to the outrageously large Keq and the remaining 0.2M of NH3 is larger than the concentration of AgNH3.
I have 1 week to lock in for this
Counting down the days!
jeremy gyatt is the goat sigma alpha bulusu
Thanks!
I'm scared
I on the other hand, suffer alot with FRQs compared to my MCQs
I understand. Fortunately, we have lots more released FRQs to work with. CB doesn't release nearly as many MCQs.
MCQs are killing me
These are some of the tougher ones. You'll often find a lot of MCQs that are easier than these.
do you know my teacher alissa clark at bardstoen high school
I do. Say hi to Ms. Clark for me!
It’s over
40 minutes left….
i am not buying the ultimate review packet but ill get a 5 anyway
That's ok. I want to see you get that 5 either way!
i hope both sides of your pillow are cold and your phone is always charged. you are a saint, id probably fail chemistry if it wasnt for you. god has a special place for u in heaven king
Thanks for your kind comments! My phone is at 91%, so I'd say things are good. Keep studying and you'll do great next week!
