Jeremy Krug you are my Jeremy Goat (Greatest of all time)

[@JeremyKrug]

Thanks so much, I try hard to make good videos!

[@hudsonharris7506]

Dear Father Krug, Your towering presence and booming voice have sculpted not just my understanding of chemistry, but my very appreciation for the sciences. Under your tutelage, I've morphed from a mere student into an ardent disciple, eager to absorb every bit of knowledge you impart. Your rugged masculinity and heart of gold blend seamlessly, making you not just a teacher, but a beacon of inspiration. With each dynamic lecture, captivating demonstration, and late-night tutoring session, you, Kruggie, have etched yourself into the fabric of my academic journey. Long live your reign in the realm of academia, for your legacy as King Krug will endure far beyond these classroom walls. Thanks Papa Krugger! Yours in admiration, Hudson

[@JeremyKrug]

I'm so happy that my work has made a difference for you this year! I hope I've helped you deepen your appreciation and love for chemistry. Best wishes on the big exam Monday!

Mr. Krug im naming my future son after you

[@JeremyKrug]

Will you be naming your son "Mr. Krug?" LOL I'm so glad I've made an impact on you this year. Thanks for watching!

[@edvantagetv]

Mr. Krug. Thank you so much. I wrote my school's model AP Chemistry exam today morning and you have no idea how much you helped me. Please never stop!

[@JeremyKrug]

I'm so glad my videos have helped you out this year. And I'm not planning on stopping anytime soon!

[@supershaw3651]

Mr. Krug, thanks for all you have done. I'm only about two hours to your south in TN, and I've been studying your full AP Chemistry playlist along with Princeton Review's AP Chemistry Premium Prep book, and I'm on Unit 3 right now. There are 5 tests in the book, and I'm giving myself practice on the first one. However, the remaining 4 will be used as real tests, so a 5 is obviously my desired score. My high school never offered AP classes, and now I'm going into my third year in college to take General Chemistry I and II, so I figure that going through these with mastery will lead me to steamroll through those courses. I also had a Chemistry teacher so bad in high school that I took nothing away from the course. Chemistry was my least-obtained knowledgeable subject until now. You changed that. It might now be one of my favorites, though I will be a meteorologist. I don't know how true it is, but I head that a score of 100% full marks was attained by only 3 people in the entire world. Even a 72% is sufficient for a 5, which seems lenient. I also plan on taking Organic Chemistry I and II, but I've heard that those courses are the hardest courses in college ever. We shall find out... lol. Great work, man.

[@JeremyKrug]

Thanks so much for your comment! High school chemistry is a tough class for so many students, so I'm glad that my videos have helped you this year. Best wishes as you progress through your college chemistry classes!

[@supershaw3651]

@@JeremyKrug Absolutely. Chemistry is a very appealing, amusing, and interesting subject to me. I'm going to be a meteorologist, so chemistry doesn't have that much to do with it, but it's still a very interesting subject to me, so I still plan on taking all the General and Organic courses. I appreciate the outreach, and I'll continue to use your videos as imperative resources.

[@studyjoy3763]

@@JeremyKrug Hi Mr. Krug! I actually had a video suggestion for you which I think would be exceedingly helpful. Throughout all my practice tests I keep consistently getting questions about lab related chemistry wrong, such as reading burettes, differentiating between volumetric flasks and graduated cylinders, and just writing lab procedures in general. For the 2022 and 2023 FRQs, College Board has been asking students to write lab procedures, so if you could make a video on some important lab procedures and lab equipment, that would be EXTREMELY helpful! Just a suggestion :D. Thank you for your help!

[@studyjoy3763]

Lol nevermind-- I just found your laboratory review video from last year! It is exactly what I need. Thanks again!

[@JeremyKrug]

[@OrigamiCrane-st9uc]

At 8:51, why we were able to use the concentration of NaOH from the endpoint if the equation MaVa=MbVb applies only at the equivalence point?

[@JeremyKrug]

What we observe in the lab is called the 'endpoint.' If we've chosen an appropriate indicator, we can safely assume the endpoint is very, very close to the equivalence point.

[@OrigamiCrane-st9uc]

@@JeremyKrug Ohhh okay thank you so much!!

[@HelixAdamOxford]

2:45 I might be misunderstanding but wouldnt those add up to 8 electrons?

[@JeremyKrug]

Each atom does have an octet, but the formal charge is a different form of accounting for electrons, where each bond touching the atom counts as a 1, not as a 2.

not necessary, mL is fine for this scenario

[@JeremyKrug]

You're correct, as long as you're consistent with your units, you can leave it in mL.

[@randomidiot4736]

hello sir, i appreciate your videos a lot and they are very useful, though i am a little confused regarding a thing, if the value I write is extremly close to the one on the scoring guideline though is slightly different, am i still getting the point for that question ? (i.e if the scoring guideline accepts 0.035, and 0.036 with decimals carried, do i lose the point for that question if my answer was 0.034 ?).

[@JeremyKrug]

I think you'll still be okay with that answer. Thanks for watching!

[@MeenaAlfalahy]

When do we use percent yield?

[@JeremyKrug]

The question will specifically ask you to calculate percent yield. This is when a reaction doesn't produce as much product as we expect it to.

[@posatok273]

For % error, is it okay if we switch the correct answer and the calculated answer in the numerator, as long as the denominator stays as the correct answer? I'm worried I might switch up the numbers. I'm thinking that the absolute value would just give the same result.

[@JeremyKrug]

Yes, that's perfectly fine, as long as you get the same right answer.

[@shobhaupadhyaya880]

Hi Mr. Krug! Just a quick question (technically 2) - Are your topic videos for AP Chemistry aligned fully with Collegeboard? Like you aren’t missing anything out, right? And I have 7 days to review for the AP test, and I have not anything at all. Please help 🙏

[@JeremyKrug]

Yes, I've tried to include everything in the 91 topics of AP Chem. Check out my full AP Chem course playlist, along with my 10-minute unit review videos, work lots of practice problems, and you should be in good shape.

[@xuantinglu9793]

the question on the titration part, it's "the equivalence point", not "the end point".

[@JeremyKrug]

The question refers to what a chemist sees in an experiment. It is not incorrect to say "endpoint" when referring to what we observe in a titration. In an actual experiment, the chemist observes the endpoint, not the equivalence point. If we have chosen the appropriate indicator, we make the experimental assumption that the endpoint is equal to the equivalence point, and use that for our calculations.
