He deserves a Nobel Peace Prize. Seriously.

Nobel Peace Prize? Your use of hyperbole is appreciated!

ive watched all the tutors online, this guy teaches the best

[@timmorris6456]

This dude is an incredible teacher and I’m so grateful for these videos

[@ChadsPrep]

Glad you're finding them helpful Tim! And gratitude is one of the secrets of a happy life!

Chad, thank you so much for helping me understand chemistry. I thought I'd never be good at chemistry. I failed 1046 retook it and passed with an A. I passed organic chemistry 1 and 2 with an A thanks to your videos. I love to see professors wanting to help students understand the material. I'm using your DAT prep and love it!

[@ChadsPrep]

Kudos to your hard work paying off, Brittany - glad the videos have helped you so much!

[@chanis6307]

Thank you so much for these videos!! Using them for MCAT review now and they're the best videos I've ever used!

[@ChadsPrep]

Glad you like them, Chani S - Happy Studying!

@@ChadsPrep Thank you- do you have a video on calculating logs and antilogs without a calculator?

[@emilyh3644]

You helped me get "A" grades in my ochem classes, and now you're helping me in biochem! Thank you so much for these amazing videos! I'm definitely going to return to this channel when I'm studying for my MCAT.

[@ChadsPrep]

Glad to hear it, Emily - much continued success in your educational endeavors!

[@ChadsPrep]

Also, I don't have my basic Biochemistry playlist on youtube, but you can watch it for free on my website: www.chadsprep.com/chads-elementary-biochemistry-videos/ Happy Studying! 👍

@@ChadsPrep Thank you! I have it bookmarked and will definitely be watching it as the semester progresses.

[@ChadsPrep]

@@emilyh3644 Excellent and Happy Studying!

I wish I had found your channel earlier. These explanations are on point!! Thank you

[@ChadsPrep]

You're welcome.

[@Omni-Kriss]

Thanks for these videos :) They are a nice supplement to my self study of chemistry!

[@ChadsPrep]

Great to hear it, Omni-Kriss - good luck with your studies!

You are a God send. Thank you, my good sir!

Thanks, Billy!

Hi Chad, for the equation you introduced at 16:50, or the shortcut equation for the ICE box method, would a polyprotic acid or base change this equation? Thank you so much for these videos btw. Passing and enjoying chemistry this semester thanks to the easy understanding of the concepts. 😁

[@nicoscool2333]

you are helping my last 2 brain cells finish my lab thank you

[@ChadsPrep]

You can do it!

[@snehasree9329]

You made it extremely easy! Great job:)

[@ChadsPrep]

Glad you think so - appreciate the comment!

[@isaacashlind6535]

Great videos!

[@satchelkrawchuk8640]

I am a little confused with your [H+] and [OH-] shortcuts. What if it was a weak acid or base where the molar coefficients were not 1, as in the change column of the table would have 2x, or 3x, etc... That would mean that the top of the Ka could be [2x]^2[x] for example. I am assuming for thus the shortcut doesn't work, since you would have to take the cube route. Was the shortcut simply for 1:1 coefficients? Thank you!

Chad, can you please a video on how to calculate log and antilog without a calculator? Thank you!

[@ChadsPrep]

Hello Ankita! My original plan was to be able to respond to your comment hear with a link to a new video showing how to approximate logs and anti logs (and pH calculations in general) without a calculator. But it's been a busy week, but I hope to get to it right after Christmas!👍

[@327home]

@@ChadsPrep That would be so wonderful. I really appreciate it.

[@michaelisakov1108]

Can u help me with a problem that requires quadratic please?

[@TheShibeee]

The 6.8 x 10^-4 vs 1.8 x 1-^-4 threw me off. Can you please explain why 6.8 is bigger?

[@ChadsPrep]

It's easier to see if you write them without scientific notation. They are both 10^-4 which means they'll both begin with 3 zeroes. So you're really comparing: 0.00068 vs 0.00014 And 0.00068 is definitely larger just as 68 is larger than 14. Hope this helps!

[@TheShibeee]
