Thank you so much sir I'm watching from Nigeria ❤️ I really appreciate all your efforts in putting this together 🙏🙏 Much thanks sir

i am taking biochemistry this semester, and i was searching for a video that i will understand how and what i will study. I am so glad that i found you thank you so much

[@bftinylectures4362]

Thank you for watching! I hope that you do well. I love you!

[@xyramz]

i have a test on biochemistry tomorrow and your video just saved me. Cheers!

[@bftinylectures4362]

Yay!! You’ll do great on your exam! Thank you for allowing me to be a part of your education.

[@dulcecastellanos4118]

I’ve learned more watching your videos than I have in my lectures, thank you so much!💖

[@bftinylectures4362]

😈 Thank you!

Thank you so much for the lecture. really help me in biochemistry study

to those who are confused about the sp3 is not really about the electron configuration. its about the kind of Intermolecular bond it has. if it doesn't have a double bond (no pi bond) it's sp3.with double bond, it's sp2 (2 pi bonds) and only SP for triple bonds (linear). dont worry about the detailed explanation that much. just remember sp3 has no double bond, sp2 for a double bond, with triple bond is Sp1 (no need to say sp1 bc if it's 1 its automatic invisible haha) so just write Sp

Thanks dude. This is really honorouble what you doing.

I really want to study medicine in the future, so I'm trying to study really hard now best of luck!

[@bftinylectures4362]

If I can do it and study at one of the best institutions in the country, I think you can do it as well. Best of luck, and keep studying!

I love your examples 😂😂😂 like florine eating all chips 😂 I'm understanding a lot more than I would in class with my lecturer

Thanks Joanita! I appreciate you watching my videos and I hope that you do well in your classes. Good luck and I love you so much!!! 🖤🖤🖤

you are the best man keep doing this shit im going to shout out you to everyone man

[@bftinylectures4362]

Thank you! That means a lot to me!

Hello! I am starting a biochem in the fall, and I love the opportunity to get started on my learning with these videos! I have to know! How has your journey to medical school gone so far? I also am dying to know what the "BF" stands for in your username! Thank you for making this series so selflessly!

[@bftinylectures4362]

I am applying to med school right now! I’ve gotten multiple interviews and have several interviews in August. I hope I get accepted somewhere! As for the BF, those are my initials. I’m supremely glad that you’ve decided to study with me! Thank you so much and God bless you!! :^)

why is it when i am doing the equations 1.8 *10-16 * 55.5 i end up with 9.99*10-15 ?

[@macbook2969]

Isn't the separation of mixed oil and water decreasing entropy and is more organized since water is on its own and oil is on its own so its not as random? I'm so confused by this topic, please any explanation would be helpful

[@bftinylectures4362]

Initially, entropy increases as the water and oil molecules are mixed. as the oil and water molecule separate, entropy decreases. You are correct. Transiently, entropy increases as the solution is mixed. Always remember that entropy increases in the universe, as disorder increases overtime. Think of it as like a room: initially, the entropy in the clean room is low, but as time progresses and more and more trash accumulates, the entropy increases.

[@nataliahincapie5853]

This is probably a stupid question, but how do I know if it is a strong or weak acid? Do I need to know it to use Henderson equation?

[@bftinylectures4362]

For acids, the smaller the pKA, the stronger the acid. The larger the pKa, the weaker the acid. If an acid is weak, then it'll be a strong base. If an acid is strong, it'll be a weaker base. Typically, the pKa values are given to you. If you want to think intuitively, acids that want to become more stable will be more reactive and thus have a smaller pKA. For instance, CF3 is a lot more reactive than CF because it has two more Fluorides. Since CF3 is more reactive, it wants to accept (acids accept) electrons. Therefore, it'll be a weak base and have a low pKa. You could use the Henderson equation if you're given the information, too.
