The Creation of Chemistry – The Fundamental Laws: Crash Course Chemistry #3

Today’s Crash Course Chemistry takes a historical perspective on the creation of the science, which didn’t really exist until a super-smart, super-wealthy Fr…

This lesson discusses what intermolecular (van der Waals) forces are and why they occur. We look at Dipole-Dipole interactions, Hydrogen bonding and London D…

I heard physicists say that according to Einstein’s relativity theory
matter does turn into energy thus losing mass. So in theory if i burnt 1
mole of methane and somehow collected all of the products the mass after
would never be exactly equal to what i started with. I think this is pretty
much negligible with combustion and all chemical reactions, though.
I like that nerd shirt. I want that nerd shirt. Where do I get that nerd
shirt? Give me that nerd shirt. now
Crash Course has replaced Cliffs Notes… forever! I’m kidding–they still
have a website. But I’d rather watch Crash Course because the Green
Brothers ROCK!!
Since when does Hank’s hair have a puff-level!?!
Did he go from Thought Buble to Thought cafe
Thumbs up If you noticed
how is it that the men you name as the fathers of chemistry came after the
egyptians who invented it?
Never even learned the basics of chemistry. Absolute beginner. He goes a
tad too fast for me to understand, but it is called ” Crash Course
Chemistry ” anyway I will keep watching and see what I can get 🙂 hail
Heisenberg
This might just be me but at some points he goes way too fast to understand
it all. This is coming from a person with little knowledge of Chemistry.
Still, I will be watching this series. Nothing to lose and everything to
gain.
I have ADHD and love these videos but sometimes you guys have a little
backtrack/music that plays and it totally drives me insane. I can’t focus
on what you’re saying and it kills my concentration. smh
You make Lavoisier sound like a pervert getting married to a 13-year old
girl. To be fair he married her because she had been promised to a man in
his 40’s. Women married young then because they had to. When you can only
expect to live to about 35 you have to start having babies as soon as
possible if you have any hope of raising them to adulthood then helping
your daughter or daughter-in-law with HER babies. Women today can afford to
wait until their 30’s to start having babies because women today can expect
to live into their 80’s
So we can turn ash into diamonds? Misty would be proud :P
The Creation of Chemistry – The Fundamental Laws: Crash Course Chemistry #3
This is going to sound stupid but how does the volume of oxygen being two
times smaller than the volume of water vapour show that oxygen was
splitting into two pieces? My brain is being extremely slow and cannot
connect the dots. Could someone please explain this further for me? Thank
you.
WHAT IS UP WITH THIS BACKGROUND MUSIC?!
You guys should make lesson plans for teachers worldwide. People would be a
lot smarter, I guarantee.
Hank wants to teach me about chemistry. My lack-of-focus-level: noticing
hank’s haircut as well as the fact that cc’s #’s 1 and 2 were probably
filmed on the same day
Correct me if I am wrong, but I heard Hank say “Hydrogen wasn’t inflammable
air …” at 2:55, don’t you mean “Hydrogen wasn’t FLAMMABLE air …”?
Can you please do a crash course in physics? Pleeeaasee?
this is getting me through chem in HS.
Why can they not teach ALL classes JUST LIKE THIS.
make it interesting.
I dont get any chemistry.I dont have a chemistry background-can anyone help
or suggest a website?
CrashCourse My Science teacher loves you guys!
Whats the number?
Lavoisier didn’t discover a single element. While he might have named them,
he was not the discoverer, especially not in the part of oxygen. Hydrogen
was Cavendish. Oxygen was Scheele, but Priestley was doing very similar
things independantly at similar times. Edmond Genet about Lavoisier: “I
also had the advantage during my stay at Birmingham of becoming acquainted
with Dr. Priestley who had the kindness to repeat for my gratification his
most interesting experiments on air and gases of which I sent an account to
the Academy of Paris. At that time, Lavoisier was pursuing the same
subject, and I was surprised on my return to hear him read a memorial at
one of the sittings of the Academy which was simply a repetition in
different words of Priestley’s experiments which I had reported. He
laughed, and said to me, “My friend, you know that those who start the hare
do not always catch it.”
thank you for explaining how we went from alchemy to chemestry. i’d always
thought we’d gone from one to the other through a better understanding of
atoms, but this fills out all the blanks. plus, now i can explain it to my
relatives and not have them look at me like i’ve grown a third head.
Hi Mr. Green, Can you please do videos on Physics?
A big big bigggggggggggggggggggggggggggggesssssttttttttttt thanks to you
for this great video…..:-)
This is amazing u have no idea how much youve helped me! Imm gunna pass
this test wooooo!
thanks for making this an easy lesson to pick up on something that can
seem very confusing if not for your technique on the demonstration!
*T H A N K Y O U S O M U C H !*
I wish you were my teacher instead
THANK YOU SO MUCH HOLY FREAKIN CRAP
Helped so much thanks!!!
Great ! thanks
Great teacher!
finally get it, thanks alot :))
You have helped me so much preparing for exams. I just dont’ understand my
teacher when he talks about it, but it makes sense when you write it out.
Thank you so much.
very helpful 🙂 Thank you!
That…was…beautiful. Simple and concise. Thank you so much.
Thanks.
life saver
I´m brazilian boy and i am loving this class thanks!!!
Brilliant! Thank you very much!
Thanks man!
this was very helpful, thanks! :)
I go to a private university that costs 28k a year. My chem professor took
an hour to describe what he just did in 10 minutes lol.
Great tutorial – thanks!
A* great vid
This was really easy to understand. Thank you for making this video as it
really helped to clear things up after a class taught by my student teacher
who definitely has no experience…
wow, chemistry video with lecture+lab experiment, awesome
Really good video, thanks.
