this guy and khan are the real profs i need !

Almost done with chem2. wouldn't have gotten through chem1 without your videos. Now next term I'm taking ochem. crazy... thank you so much brotha

Tbh, you're more useful than my current chem prof

Thanks！ You just saved my midterm！

ayyyy exam in 3 days, thanks for all the classes

You are a lifesaver ❤

It is really very good and useful thank you ur explanation is really good

I will prepare to my best !

Thank you for teaching me unlike my incompetent teacher.

Given the following standard reduction potentials in acid solution: Al3+(aq) + 3e- → Al(s) E° = -1.66 V Sn4+(aq) + 2e- → Sn2+(aq) E° = +0.14 V I2 (s) + 2e- → 2I- (aq) E° = +0.53 V Which of the following is the strongest reducing agent?

Ermm please is it necessary to bring the concentration of 1M for the 2nd example when you're writing the cell notation

Reduction occurs at the Cathode, Red Cat!

Cell potential is an intensive property then how can we add directly cell potentials?

How do you know which chemical equation to write for the solution

thank you

God bless you man

INVALUABLE!!!

Eating this 3hour be for ap chem test

Hello my teacher Please could you please explain potentiomtery

Just to let you know for question 7 c the answer is wrong. The Q value should be 1.48*10^-5 and the concentration of Cr^+3 is 4.52*10^-4

I love you no homo

wow

MVP

Do the ending step by step. I don’t understand that method at all

i love you

dude i love you but please increase the volume
