Hi, Chad. I don´t know if you are still there. I just wanted to reach out to say thank you very much. I am a Mech Engineer and always I have been struggling with chemistry topics, for example, Electrochemistry. I learned Fuel Cells for the PhD but always from the thermal-fluid view, avoiding electrochemistry as much as possible. Your lectures have been invaluable for my learning and your passion as a Professor shows all the time. Congratulations for your work.
Wow I wish you were my chemistry teacher I know I wouldn't be on the cusp of not passing my class your explanations are thorough and sensible I understand so much more now! Thanks so much!!
You're very welcome Darren and I'm glad you're finding these helpful. Only wish you'd found them earlier in the semester. Best wishes on your final exam!😊
That is one of my classic examples in which I attempt to make a concept memorable by devolving into less than tasteful hilarity. Hope the terrible example accomplished the task for you! Happy Studying!
You know what's funny, people that work with cattle often call the refer to a red coat (red holstein, red angus, norwegian red, red and white ayrshire, etc). I call that color brown or maybe reddish brown, but people often call it red. (this is a comment for the algorithm, not a criticism)
you say that when we added the zinc it came in the form of zinc sulfate. But did we not add it in its elemental form? Now that it turned into an ion why do we need to add some sulfate? Can't we just leave it dissolved in the water?
@@ChadsPrep yeah I'm not gonna lie its rough but I had to watch this first because when I took gen chem this was my worst topic so I had been set up to do poorly from 2 years ago
Hey Chad, I love your videos! A question for you: when you calculate the Ecell, you do reduction potential of cathode-anode. Do you multiply their potentials based on cofactors in a balanced equation? Also, do you flip the sign of the anode since its being oxidized? thank you!
Nevermind! I watched your next video! I was doing practice problems while flipping the anode sign but also using the Cathode-Anode equation and getting them wrong obviously, anyway thank you!
Hi Brenna! First, you don't multiply by coefficients from the balanced reactions in calculating Ecell; you just use the value from the table of reduction potentials regardless. Now if you do reduction potential of the cathode - anode then you don't change the sign of the anode as subtracting is already changing the sign for you. Now if you were to use Ered + Eox then in this case you would change the sign to get an oxidation potential. So you either subtract and don't change the sign or add and change the sign. But if subtract and change the sign you will definitely get the wrong answer. Hope this helps!

Definitely still here - glad the channel is helping you out so much. Thanks for the positive feedback!

Knew id come here to get the best explanation! I always read my textbook first but come here to solidify the deets!
Glad you're here, Billy!
took me a while to figure out the red cat joke lol
did not need to be reminded of the gruesome loss of my favorite barn cat 5 minutes in... but it did help me learn the concept LOL
"Red cat" - gruesome and memorable. Happy Studying!
I wish you could teach my teacher how to teach instead of teaching me! :(
Glad you found us, shayan k.
A chad moment with the red cat jokes.

this is a very clear explanation
Excellent!
Thank you for this awesome video!
Glad you liked it, Suhayla!

Such a great video! Thank you!
Thanks Shlea and so glad you found it helpful!
thank you

YES!~~~~~~~~~~~!!!!!!!!
not gonna lie
i'm not even in gen chem
i'm in electrochem and i'm very sad that you can only help me study for the introductory chapters
An entire semester of Electrochem? Sorry I don't have more for you but hopefully this helps lay a good foundation. Best to you Hailey!

red cat YIKES
G.O.A.T chem teacher ... wish I found you earlier
Thanks!
