I find the fact that reduction makes more sense for me on the electrode that loses electrons. I keep mixing these up.
and I dont quite understand why positive is gaining electrons electron flow is from - to + so shouldnt we just use that as reference for - and + poles?
Pls continue making these videos......all of my education literally comes from ur videos......
ow
Hen
at 11:01 how I learned was that to give an example from the chlorine atom again the 17 protons (positive charges) are trying to attract and keep electrons in the orbital hence the attraction force is actually divided by 18 electrons not 17 . So we have "1 protons force" that attracts 1 electron but on anion, we have "17/18 proton force" per electron.
That was great, Thanks 👍🏻
Are I and III called anomers of each other.
What does the R represent
Whose here from 2024 😂😅
u ain't alone
what does n stand for?
this vedio helped me a lot. Thank U.
very bad explanation on this one, you're just assuming people know stuff
Since I Is a catalyst how comes that it is counted for calculating molecularity ? Catalyst are not involved in calculating order and molecularity right ??
Damn this is...AWESOME !!! thanks a lotttttttt man
Very nice video brother. I need this for my medicine studies in Germany. Grüße aus Deutschland!
"peroid" table?
bless
I appreciate the explanations for the chemistry, but there is no calculator allowed on the MCAT, which makes the calculations very difficult. Is there a way to learn it without a calculator?
how do I know the Hz for the different protons (coupling constant)?
A good explanation . Thank u
Abe angrej ke aawald hindi me samjha
❤❤❤
What happens after an electron falls from higher energy level to the 2nd energy level? It emits photon...then it must fall to the ground energy level and emits UV. BUT is the photon first emitted still visible?? If yes,then for how much time does it remain visible and for how much time is the spectrum visible?
GRAH GRAH EVERYTHING K
thanks a lot , my concepts are finally looking clear , i can finally connect dots of these quantum numbers
Very informative 😊
Thank you! My textbook was so confusing and the derivation of the equation was not clearly explained anywhere! This made everything click
thanks for showing the mechanism really great video.
Good
One of your best videos. My teacher never taught this in a way I understood so this clarified all my questions! Thanks
God bless your soul
Who is the lecturer? He is a fabulous teacher!
ua-cam.com/video/V9JixmPdeuk/v-deo.html why does the oxygen lose a double bond instead of chlorine becoming a leaving group? and how do we know there's a second step?
Amazing explanation, thanks!!!
THE BEST!!!!
wtf
having this under MCAT prep and using a calculator is mad disrespectful
Thanku
First 6 minutes was not necessary...
Thank youv❤
To be fully rigorous, if Energy is measured in Joules, what exactly does a kJ/mol measure? Unless the mol is not really a unit and could be omitted, it seems to me that a kJ/mol can't be just "energy" but something else.

Please i want to know how you got 30 before subtracting it from 40🙏
Hey I have a doubt that can I draw the NMR spectra without leaving any gap in the baseline ?
Nyc video
what did you do to khan? wheres his body?
Thank u
You could use: MV/n = MV/n n being the moles you obtain fron the balaced chemical equation.
What a great video keep it up
