Happy Studying!
Just wanted to thank you for creating your channel. You've helped me through my MCAT prep more than words can describe! I'm sure I speak for many other students out there.
thank you, Chad!
You're very welcome Cythia! Best on the MCAT!
this dude is god damn legit
Thanks Norman! Glad you found this video helpful!
I've never in my life understood the concept of the Cells this is the 1st time ever that it has made sense!! WOW Amazing...
Glad you were able to finnally get it!
studying the gamsat in australia, thank you so much for this!
Very welcome from the USA - Happy Studying!
You deserve way more subscribers!
Thanks Mariah! Glad you're finding my videos helpful!
this video helped me a lot. thank you very much
Glad to hear it MD - You're very welcome!
Hi, why do you put Mn+2 + 2e---> Mn ? the question says Mn/Mn2+. don't they both have to be in oxidization from or anode form? in the video, they are in reduced form or cathode.
I am from India and I don't know why but I find it helpful for me. Thank you 💜
Great to hear you find this helpful Sneha and welcome to the channel :)
You helped me with equilibrium now withh this... thanks
You're welcome, Santiago!
Really awesome dude
Thanks a ton!
hey got a question:
why do galvanic cells have a positive cell potential?
Hello Martin! Galvanic cells have a positive cell potential by definition. There are two major types of electrochemical cells: Galvanic Cells and Electrolytic Cells. The big difference is in spontaneity; galvanic cells are spontaneous and therefore have a positive cell potential and negative delta G, whereas electrolytic cells are nonspontaneous and therefore have a negative cell potential and a positive delta G.
Hope this helps!
These videos have helped me so much thank you Chad
You're very welcome Shanta'!
thank you bro, you just saif me
Glad to hear it!
We are not a British like you to know and understand English we are Indians Hindustani
English speaking course kar le
please talk in Hindi in any videos
Be universal!
@@TechnoSan09 yes man I know but ur English is not so understandable . Even u can't take some stop.
