I am so incredibly grateful for this series of videos, how can I express my thanks? I need to pass chemistry and am struggling at age 46; I never took it in high school. Today I begin watching your entire series so I can fill in the gaps in my learning -- maybe the pieces will fall into place! Thank you so, so much!
KhanAcademy is the best, Ive been out of school 10 years and just jumped into a biomedical science degree without any chemistry knowledge...they don't teach you crap in college, haha everything I know at this point, is thanks to Khan. I love it
You really blew my mind with the hydrogen = 1 proton. I managed to get a 5 in AP biology, and I understood most the concepts except little details like the splitting of water in photosynthesis. Watching your videos allows me to understand chemistry, which I never did due to a bad teacher, and string together all these pieces of information I have floating around in my head! Thanks so much for taking the time and effort to make these videos!
I always say that a teacher is the most important job ever. Because without people to teach us stuff, our society would be an under educated anarchy. But you, you don't ask for anything in return. you don't ask for money to watch these videos or anything like that. So i just wanna say thank you!
@dxStevenS Ur not alone with chem teachers that teach chaotically. It's hard to point out why it's a crazy class. I like Khan a lot. I watched his videos for DE and am just starting my chem classes. He's very methodical and thorough.
i would just like to say thank you for your hard work. if you ever read this i hope you know that I really mean whay i am saying. this must take hours and hours putting these together so i really appreciate it
I go to the Maine School of Science and Math and Sal is officially way better than any of my teachers and his videos have saved my school life many times :)
At 6:17, I believe he meant to say "for every 6 carbons, there are 12 hydrogen and 6 oxygens"...he said 1 oxygen. Regardless, thank you for ALL you videos...calculus, physics, chemistry...all are very helpful and most importantly easy to understand!
our chem teacher sux and screams at us if we didnt know what he means, so we dont ask him anything and we get low grades, this helped me out throughout the years :D thnx
What you do is amazing! I have found some of these relevant chemistry videos very very helpful. I learn more in 15minutes than i do in a class where we cover the same thing in 50 and i still dont understand it. Anyways what would be GREAT is if you could have a team that agrees with doing things for free so there could be a much wider useful youtube channel/s of knollege. What you do is brilliant BUT you need a TEAM! Teams get more done! Keep up all the good work
I knew someone who used to spend all day every day doing something with molecular structure, and he used to boast that nobody - not even his supervisor - knew what he was doing. I thought 'Great. I wish MY supervisor didn't know what I was doing, so she would have to trust me.' The kind of supervisor I have, knowing something she didn't would be a good thing since I would get even more respect from her. He created new drugs for heart disease and he was a doctor.
I've been a big fan of Khan Academy for years and it has helped me through many a math test. However, if you only learn one thing watching all of the many videos, it has to be that Sal is not a great speller. Makes me feel better about my own lack of spelling acumen. P.S. I had to spell check "speller"
Thank you! I think i 'd better self-studying and watch youtube for the learning of chemistry instead of pay all the attention in school that i dont really understand,
Chuck Norris You read, write and speak English right? Well English came from (drum roll) ENGLAND! And in England they spell it sulphur. So you're wrong
hey sal if you get the time could you make a video about Types of Reactions In these questions we are given the products or reactants and we are supposed to identify the results after a reaction. thanks
hey Sal! i think u explain really well but can u explain empirical formula in detail like from what it is to how to write it (also do u use the crisscross method to solve it??) plz reply asap!
i hope my chemistry teacher reads this: WHY CAN'T YOU BE GOOD AS SAL WHEN IT COMES TO TEACHING D:< .....stop talking about your life....no one freaken cares and start teaching us chemistry like this guy...he's doing great :D
I really love his humour, well you know. Great vid thanks, It helps with my revision. After watching all your videos, I'm gonna start skimming through the textbook and start doing some calculations T_T
I love the video...I finally understand basic chemistry and even love it...thank you for your video because at least dumb people like me finally understand chemistry.
@bodetcorreya YESS i completely agree, i have 4 teachers for chemistry and they all suck, they're just more worried about challenging us making the class almost impossible to pass, im really having a hard time understanding everything. thats why im always on here searching and teaching myself cause i dnt get them... its people like this guy that explain things so simply that i feel like theres hope for me in passing.lol im relieved!! Thank you for posting :) i still hate chemistry tho..
Because our bodies are made of that 90 % water to power just about every reaction in our body through hydrolysis, which given the name, requires water. If the amount of water in our bodies gets too low, then we start to dehydrate which soon seizes our bodies ability to break compounds down into there basic forms. That's just one of the reasons.
I'm shedding tears of gratitude, thank you !!!! I was googling this for half an hour and finally I found this amazing channel!
13 years ago is crazy

If I pass my chemistry midterms this week I have the Khan Academy to thank....

When you unconsciously use British English 😂
Khan academy has helped me lots.
Thank you for such wonderful videos...plz do keep sharing more such videos!!!
just for those who are interested, the benzene actually has two dohnuts where the electrons are free to move, one above and one below the molecule
THANK YOU SOOOOOOO much! ur videos really help me in my studies as i'm appearing for gcse boards...
can you please be my chemistry teacher?
Yes pleasee🥺💖💖
🥺
You must have graduated now 🥺
He's accent is perfect until he says proTon. lol
but i love that dude! the amounts of times he saved my life
I honestly think they should replace homework with youtube videos, I learned more from Khan than I did from my teacher! =D
Love these videos, I wish you were my actual chemistry A-level teacher cause trust me, you'd be better
Wow your really simplified this for me. My Chem teacher was driving me crazy with this. Thanks

the one thing i have to say u is
thank u,
you tech big concepts in very small time
which i have to suffer a lot know the same in my collage.
Khan Academy always saves my life. Thanks a lot for these amazing videos!
Taught me more than the whole year studyin' in class!

You are great, You ar helping me alot for mY upcoming examination
Good voice, Excellent presentation WELL DONE!!!👨🎓👨🎓👨🎓
you're such a beauty. i understand chemistry now. thank you so much !
hey... you are doing a real good work ,teaching others. may you live long for this program you are are doing.
Thank you for making it easy to understand.
our chem teacher sux and screams at us if we didnt know what he means, so we dont ask him anything and we get low grades, this helped me out throughout the years :D thnx
you do chem also? you saved me in physics and now youre joggin my memory of empirical formulae thanks
This helped me so much on how to figure out empirical formulas
helping me review for my chemistry exam tomorrow! thanks!
the best chemistry teacher i ever had!

hi mate
damn im actually inderstanding stuff!
the colors make it wayy easier thanks again!
this guy knows everything.
im gonna pass my tomorrow exam thanks to you :D
This vid helped me for couple of basic things. Thanks & wish to see some more from u.
I wish I had looked online to learn the sciences. Everything would've made a lot more sense.
Best vid I've ever watched. Dude you the best
this helped me so much thanks for posting it and this helped me study for my test... ur videos r great and ur really smart
Your calculator looking absolutely ancient
You'd be an awesome teacher!
Thanks for the vid! Got more out of one video than I have gotten out of six class periods....
I knew someone who used to spend all day every day doing something with molecular structure, and he used to boast that nobody - not even his supervisor - knew what he was doing.

I lover your panel at Stanford Big FAN, keep up the good work.
It's spelt Sulphur in Canada
... Lol how many countries do you see burning the Maple Leaf flag?
spelled*
Sarah Griffith lmao!
Sarah Griffith
It's spelt Sulphur everywhere (English-speaking-countries) except America.
Same here in India, it’s spelt Sulphur.
I've been a big fan of Khan Academy for years and it has helped me through many a math test. However, if you only learn one thing watching all of the many videos, it has to be that Sal is not a great speller. Makes me feel better about my own lack of spelling acumen.
P.S. I had to spell check "speller"
He makes up for it by knowing just about EVERYTHING else
Benito Calabria Well you better call Sal
I miss that show!
Thank you! I think i 'd better self-studying and watch youtube for the learning of chemistry instead of pay all the attention in school that i dont really understand,
wow that was great! EXTREMELY helpful! It makes me like chemistry a little lol
Ten years later~
Something I've learned from watching KhanAcademy videos: Khan really likes Magenta.
Dear brother , I like u and ur videos
THANK YOUU!! YOU HELPED A LOT
Love Your videos Khan- your the best ; )
Thank you!!! i learn more from you than my professor lol
you have a good voice for radio!!!!
05:14 "It's not a ph it's an f"
WRONG! In the UK anyway. Lol.
Mr. Khan your are a beast!!!! Thank you so much
MR BEAST
MR BEST
If my chem teacher were this guy, I may actually show up to class.
Thanks for uploading, you are the best!
Good luck on your test tomorrow!
This will help me for tomorrows final test =D
that was really helpful!
"Most of" and "how much of" are imprecise and could refer to volume, mass, or quantity.
This was extremely helpful. Thank you!!!
My blood boiled when he said Sulphur was spelt wrong...
it's spelled sulfur in america and that's the only place god pays attention, so suck it the fuck up and god bless america
Chuck Norris Please shut up. And I'm an American too, doesn't change the fact that you are acting like a pretentious patriotic hillbilly.
Chuck Norris You read, write and speak English right? Well English came from (drum roll) ENGLAND! And in England they spell it sulphur.
So you're wrong
I like the inbred royal look.
Jack stratif HAHAHA Very good!
(I certainly don't like the royals, but American arrogance is far worse)
hey sal your videos are great!!!
hey sal
if you get the time could you make a video about Types of Reactions
In these questions we are given the products or reactants and we are supposed to identify the results after a reaction.
thanks
Do you have videos on calculating empirical formula from molecular formula?
The RK it can be millions of chances...
CH can be C2H2. C999H999
@Budisawsome Its a tablet. He writes with a stylus on a board that is hooked to his computer. The computer translates this to the screen.
Gosh this video is really old 😅 but still useful!
Great video> Good to see another genius that's missing the "spelling" gene. lol, hey we're not Mathematicians. Keep up the gr8 work Sal. Stay n touch.
hey Sal! i think u explain really well but can u explain empirical formula in detail like from what it is to how to write it (also do u use the crisscross method to solve it??) plz reply asap!
i love how ppl going crazy over spelling errors, u get what he's trying to say dont you?
i hope my chemistry teacher reads this: WHY CAN'T YOU BE GOOD AS SAL WHEN IT COMES TO TEACHING D:< .....stop talking about your life....no one freaken cares and start teaching us chemistry like this guy...he's doing great :D
good vids sal, idc if you can't spell empirical. thumbs up
Without you, i would probably fail my chem final tomorrow...
I really love his humour, well you know.
Great vid thanks, It helps with my revision. After watching all your videos, I'm gonna start skimming through the textbook and start doing some calculations T_T
way better than my chem class
Thanks a lot for explaining so simply. Actually chemistry is easy when you have a teacher who konws to teach chemistry, if not its hell.
I love the video...I finally understand basic chemistry and even love it...thank you for your video because at least dumb people like me finally understand chemistry.
@Broccolidiesel its funny that even when he is using a stylus he has such neat handwriting
Thanks helped me a lot
Great vid ...sulphur
Thanks so much! I finally understand this!
how can someone dislike these videos?
Seriously what an awesome manly voice =]
@Budisawsome
He utilizes an electronic pen on a special board connected to the computer, allowing him to "write" on the computer.
i WANT u AS my Chemistry Teacher
goiog
this guy is awsome
wow I was 4 when this video was published 😅 I'm now (almost) 17 and watching this in prep for my chemistry exam
omg sameeee
How r u guys studying that at 16-17 yo , in my country i study that at 13 yo 🙂↕️😭
@bodetcorreya YESS i completely agree, i have 4 teachers for chemistry and they all suck, they're just more worried about challenging us making the class almost impossible to pass, im really having a hard time understanding everything. thats why im always on here searching and teaching myself cause i dnt get them... its people like this guy that explain things so simply that i feel like theres hope for me in passing.lol im relieved!!

How would some one have a bag of benzene, wouldn't it just drip out of the bag ??
may be the bag is of plastic
