I'm doing A Level chemistry and my teacher rushes through the topics so fast that a lot of it just goes straight over my head. Here its all covered in one 10 minute video. This is simply golden. Thank you so much Hank. I really needed this :D
I love how I'm cramming for a chem 2 test tomorrow and I'm focused, then he says one direction and in the corner of the screen is a one direction concert going on, now there is a concert in my brain.
Thank you for your videos! My chem/bio teacher left my school and was replaced by a teacher that doesn't appreciate those who have more visual and pattern thinking minds, so I'm glad I can still pay attention to these.
The best way to study for a tea you have RIGHT tomorrow is to listen to a UA-cam video with a quirky guy surrounded by atoms and weird clay sculptures using a lot of funny animations to explain stuff that your monotone teacher just makes boring. Thx for this vid
After you finish the basic chemistry stuff, try to tackle organic chemistry. I'm looking forward on seeing mechanisms explained. That will be... fun. :D
Wow, this video literally explained how equilibrium works without confusing me. This video is going to help me write my discussion essay for "Separation of Cations". Thank you!
Thank you. One thing to remember though is that people can have bad days and not everyone responding with anger is an idiot or a troll, and it is easy to get heated on topics you care about. I try to respond in similar tones to the people who reply to me. It is strange to have a good debate in a Green bros video though since there are a lot of fanboy/girls and younger people with strong feelings and a sense that they are always right. But thank you for listening, I hope you have a good day to.
Great Video. You should read Master Mind (The Rise and Fall of Fritz Haber, The Nobel Laureate Who Lunched the Age of Chemical Warfare). A very interesting book.
NIGIHAYAMI Kohaku Nushi Pressure and volume are inversely proportional according to Boyles law (Decrease volume, increase pressure). If you decrease the volume, it's expected there will be more collisions between the particles and the wall of the container. Therefore it will increase the pressure within the container making the system favour the reaction with less particles to get back to equilibrium. It's also good to note that concentration is directly proportional to pressure, so if the pressure increases; so will the concentration...and volume will decrease (because it's inversely proportional to pressure). :)
M8 this is crash course not safe course lol...he does talk really fast though, but he’s fitting 1 or 2 class periods worth (at least in my AP Chem class at school) of info into 20 minutes.
If only this video came out a few months ago when I did my Chemistry GCSE! Still super useful though and a good reminder of something I otherwise would have forgotten!
Nice video, thanks a lot for it. However, I was a little sad that the effect of catalysts seemed to have been gleaned over. Personally I think it's interesting to introduce homogenous and heterogenous catalysts, and show how Ni is used in addition reaction of alkenes.
From what I can gather on a quick search the answer is yes and no. The world population has hit its production cap for food many times, but only during times when production drops are we over that line, since it is impossible to stay over the line for long due to starvation. Today is actually fairly unique in that we have the necessary production capacity to feed the world and population growth is slowing down. The main problem is people can't afford to buy the food we have in abundance.
From all I know, Youd need a closed system for the 3 H2 + 2N2 (both directions symbol here) 2NH3 to happen infinite times. Since you'd have to add energy if you did this in an open system, Due to the second law of thermodynamics.
Küsh_Lord Yes, equilibrium cannot happen unless you have a closed system. For ammonia, it's not about the energy, so much as the fact that all reactants and products are gases - in an open system, they would all just diffuse away, and would no longer be available to react in either direction. The second law doesn't come into play here other than as it influences where the equilibrium position will lie (where ∆G = 0)
If you think about it as equilibrium, where food demand and production are just about equal, then it is the norm. Outside of that are the booms and bust created by climate changes like the little ice age and the warming period before that. I would say helping people improve economically, will automatically give them a greater ability to feed themselves, so yes in the capitalist world we live in economics are the most import. Yes thank you, It has been a good debate. Have a nice day:)
I just would have said outright that each time you put a stress on an equilibrium, yes it does return to equilibrium, but a different equilibrium than what it was at before. Otherwise a great intro!
thnk you! for making me understand the concept of equilibrium.i m really grateful to you,but studing chemistry is soo much cumbersome cuz we r going to study about things that we reAlly cannot see with our naked eyes.😉
its like our understanding of the cause of ulcers, turns out its the result of a very complicated proccess between our microbiome and other products of our sugar metabolism, same thing with healthy soil and food output, just because you witness plants shoot up when you dump chemicals in the ground doesn't mean its a simple one to one correspondance, soil similarly is the results of interaction between trillions of microbes, miccoorhyzal fungi and general soil carbon content among many many other things. . genomic analysis of soil microbiomes are routine now because agriculture has come to this understanding, its not just put N, P, S in and wait....much more complicated.
Ditto, although the WiPhi ("WirelessPhilosophy") UA-cam channel, as well as several university profs posting their lectures online, 3-minute philosophy, etc. all meet that need (though not necessarily with Vlogbrother style!).
how did it caused an explosion? for me as far as I know, the chemical reaction between the nitrogen gas and the hydrogen gas will produce heat because bonds are being broken and new bonds are being formed.. is it enough to produce an explosion????
I have assumed there was enough food to feed the worlds population before the population started to grow very fast...Think that's true? I think it is, it mightn't have been evenly distributed (just like it isn't now) but there was probably enough to feed everybody. The non-fatal effects of malnutrition is a good point, hadn't considered that. I've run into a few trolls here as well, It's exceedingly refreshing to give my brain some exercise on YT with a non-hostile intellect :)
Faith Savery solubility is the ability of a substance to dissolve in a substance (like water). Polar molecules tend to dissolve in polar substances and non-polar in non-polar. If the molecule has dipoles or H-bonds it is really likely to dissolve in water. I’m pretty sure crash course already has a video on solubility
Since exothermic reactions produce heat that heat tends to favor the reverse reaction. "If heat is added to the reaction, it forces the reaction back to the left", "but if heat is removed by cooling the reaction mixture, the reaction will proceed to the right" I listened well, but somehow i'm confused.. pls help?

3:52 'everything that happens in one direction happens in other direction' ... 'other direction' maybe a good name for a boy-band.
i know you said on every episode
The more you learn about chemistry, the more you realize what you previously knew was wrong.
Kali Elaine That quality is true for all knowledge though.
Basically an outcome of every science course I have taken haha.
George Abreu All knowledge except for math. Math dont lie. 😂
from a certain point of view...
Kali Elaine true
You guys are the only reason I'm not failing most of my classes...
Same

hey there cutie
I’m revising this for my GCSE’s nahh
This is truth. XD
So how did u do for your A levels
Jokes on you Chem quiz, this UA-cam channel exists.
God bless your kind soul, Hank Green. I needed this.
Me too!
I suck
God isn’t real
@@ComplexCarmine lol
I love how I'm cramming for a chem 2 test tomorrow and I'm focused, then he says one direction and in the corner of the screen is a one direction concert going on, now there is a concert in my brain.
When you think he already explained everything there is to be explained, but it turns out to be just the intro :')
Thank you for your videos! My chem/bio teacher left my school and was replaced by a teacher that doesn't appreciate those who have more visual and pattern thinking minds, so I'm glad I can still pay attention to these.
That part where Muldoon from Jurassic Park got wrecked by Predator was funny. Thank's hank.
Fun isn't something one considers when balancing the universe.
But this... does put a smile on my face.
Honors chem final in 2 days. I have watched like 20 episodes over the past weekend
Theres def gonna be a big equilibrium problem on the ap exam so im here 3 hrs before it!!
Oh hank, thank goodness crash course exists :) I love this so much!
yuppy
i love hank green so much i hope he is happy and eating good and is getting enough sleep and is well hydrated
Hank, don you know what we do with liars in chemistry 2:55
thanks for teaching an entire chapter in ten minutes that my teacher couldn't explain over the course of two weeks
had wasted years understanding this in class but now... its like crystal clear..love yáll.
Is is bad that the only thing going through my head is that Thanos would _love_ this class?
Thank you so much omg. I have a test tmr and i learn better watching your videos than class....
Hank, what do we do with liars in chemistry?
As you nicely put it, we kill them. Right, Hank?
The best way to study for a tea you have RIGHT tomorrow is to listen to a UA-cam video with a quirky guy surrounded by atoms and weird clay sculptures using a lot of funny animations to explain stuff that your monotone teacher just makes boring. Thx for this vid
After you finish the basic chemistry stuff, try to tackle organic chemistry. I'm looking forward on seeing mechanisms explained. That will be... fun. :D
The way you described pressure's effect made so much sense!! Thank God for this channel
Nikitha P. Me too found these all videos helpful, For math I watch on mathbff it is great channel too!
i’m here because i’m a nerd that loves science since middle school
I love the Thought-bubble-John cameo at the beginning. And with Thought-bubble-Henry! :)
Came to see how Hank pronounces "Chatalier." Stayed to study for my AP tests. Great as always, Hank!
Love Crash Course Chemistry! Very helpful and very intriguing
Wow, this video literally explained how equilibrium works without confusing me. This video is going to help me write my discussion essay for "Separation of Cations". Thank you!
"The Blue Side"
**Blue Side starts playing in the bg and stirs up all the feels**
And how tf did I find an ARMY here... same bubs same...
3:54 pop out/highlight the double arrows!
You guys are wonderful! I always watch Crash Course to help understand my online classes! Thank you! (:
AP Chem 2019 !!
M M why are everybody in ap watching this I’m in regular class and my teacher is making us watch this
watching these crash course videos in 0.5 speed makes me chuckle
Men... this videos ARE GREAT!!!!!! THANKS!!!.... and please... keep doing it!!!!.... also, I enjoy the biology ones too!!
Thank you.
One thing to remember though is that people can have bad days and not everyone responding with anger is an idiot or a troll, and it is easy to get heated on topics you care about.

Hank's holding a copy of The Fault in Our Stars in the "balance between work and play"...
Great Video. You should read Master Mind (The Rise and Fall of Fritz Haber, The Nobel Laureate Who Lunched the Age of Chemical Warfare). A very interesting book.
Thank you, you have saved my life
First day of year twelve and all i can think is "thank you so so so so so much for the existence of crash course"
Thank youuuuuu hank! U and John are the best teachers! I also enjoy thought bubble XD (cute drawings)
coming in clutch yet again and saving my chem grade
This channel is seriously getting me through my a-levels
I have my finals tomorrow and just now I find these videos....great
Well, Hank talked about pressure and temperature can change the side of the equilibrium reaction, so how about volume? does it affect too?
volume is the same as concentration which he discusses at the start...
NIGIHAYAMI Kohaku Nushi Pressure and volume are inversely proportional according to Boyles law (Decrease volume, increase pressure). If you decrease the volume, it's expected there will be more collisions between the particles and the wall of the container. Therefore it will increase the pressure within the container making the system favour the reaction with less particles to get back to equilibrium. It's also good to note that concentration is directly proportional to pressure, so if the pressure increases; so will the concentration...and volume will decrease (because it's inversely proportional to pressure). :)
GhastlyDesigns how can I forget about Boyle's? So stupid of me! Thanks anyway :)
No worries :3
i've an exam tmw about this chapter & i had restored all informations about this chapter after studing ! .. thank you doc. ;)
i just learn this at school... this video is really helpful..
You taught me what my teacher couldn't in a week
CRASH COURSE PHILOSOPHY! YESSSSSSSSS
Would you please talk a little bit slower?You are disturbing the equilibrium of understanding talking too fast! :P
Really!!!:(:(
You could change the speed of the video, you know. :3
True that though! :P
i sped it up, too slow
M8 this is crash course not safe course lol...he does talk really fast though, but he’s fitting 1 or 2 class periods worth (at least in my AP Chem class at school) of info into 20 minutes.
If only this video came out a few months ago when I did my Chemistry GCSE! Still super useful though and a good reminder of something I otherwise would have forgotten!
Physics please hank.
Thank you for never forgetting to be awesome.
The new equilibrium would have fewer living people in it, so yes fertiliser is saving lives.
It's 2:43AM and I'm cramming for my chemistry final
How did it go?
so in an uncontrolled equilibrium, will there be any ammonia produced since whatever is being produced keeps on decomposing?
Nice video, thanks a lot for it. However, I was a little sad that the effect of catalysts seemed to have been gleaned over. Personally I think it's interesting to introduce homogenous and heterogenous catalysts, and show how Ni is used in addition reaction of alkenes.
This is because catalysts don't affect equilibrium.
0:07 holding the cartoon version of the fault in our stars haha
Equilibrium is like the coolest word ever.... It's my nickname in various games...
From what I can gather on a quick search the answer is yes and no. The world population has hit its production cap for food many times, but only during times when production drops are we over that line, since it is impossible to stay over the line for long due to starvation.
Today is actually fairly unique in that we have the necessary production capacity to feed the world and population growth is slowing down.
The main problem is people can't afford to buy the food we have in abundance.
at 10:04, you misspelled Le Chatelier's Principle
Very helpful. :D
From all I know, Youd need a closed system for the 3 H2 + 2N2 (both directions symbol here) 2NH3 to happen infinite times. Since you'd have to add energy if you did this in an open system, Due to the second law of thermodynamics.

The second law doesn't come into play here other than as it influences where the equilibrium position will lie (where ∆G = 0)
On the subject of Le Châtelier, I just discovered that I share a birthday with him. Today!
My favourite episode!
u make learning fun :')
When it’s dead week, the only equilibrium we have in our lives are the questions on our finals
Thanks! :D
"A wild night at the cheesecake factory" - Oh, how I love you.
thanks! really helped!
straight fire
If you think about it as equilibrium, where food demand and production are just about equal, then it is the norm. Outside of that are the booms and bust created by climate changes like the little ice age and the warming period before that.
I would say helping people improve economically, will automatically give them a greater ability to feed themselves, so yes in the capitalist world we live in economics are the most import.
Yes thank you, It has been a good debate. Have a nice day:)
I just would have said outright that each time you put a stress on an equilibrium, yes it does return to equilibrium, but a different equilibrium than what it was at before. Otherwise a great intro!
For gods sakes man, if I would of seen this series before my last exam I wouldnt've of failed it! SHITTTT
Hank #1 is missing from the intro! D:
thnk you! for making me understand the concept of equilibrium.i m really grateful to you,but studing chemistry is soo much cumbersome cuz we r going to study about things that we reAlly cannot see with our naked eyes.😉
thank you.
OMG Please talk more sloooowwwlllyyy !!!
its like our understanding of the cause of ulcers, turns out its the result of a very complicated proccess between our microbiome and other products of our sugar metabolism, same thing with healthy soil and food output, just because you witness plants shoot up when you dump chemicals in the ground doesn't mean its a simple one to one correspondance, soil similarly is the results of interaction between trillions of microbes, miccoorhyzal fungi and general soil carbon content among many many other things. . genomic analysis of soil microbiomes are routine now because agriculture has come to this understanding, its not just put N, P, S in and wait....much more complicated.
Anyone watching this before C3 tomorrow?
Final exam tomorrow and I waited till today to study
I heard it out on the street first 😑
Wait, so does adding heat to the reactant side shift to the right side or to the left side?
could you please do an episode about titration please
I have a test on this tomorrow
I WANT CRASH COURSE PHILOSOPHY!
Thanks
Ditto, although the WiPhi ("WirelessPhilosophy") UA-cam channel, as well as several university profs posting their lectures online, 3-minute philosophy, etc. all meet that need (though not necessarily with Vlogbrother style!).

Are these prosses the basis for most oscillating reactions?
4:00 so like osmosis
Holy shit, yes 0.o please.
thanks hank
Do a video on solubility please!!
Faith Savery solubility is the ability of a substance to dissolve in a substance (like water).
Polar molecules tend to dissolve in polar substances and non-polar in non-polar. If the molecule has dipoles or H-bonds it is really likely to dissolve in water.
I’m pretty sure crash course already has a video on solubility
Faith Savery I also heard from my teacher that the AP Chemistry is ONLY going over unit 12A-12B this year
I'd rather hear anything from Hank than out on the streets.
Since exothermic reactions produce heat that heat tends to favor the reverse reaction. "If heat is added to the reaction, it forces the reaction back to the left", "but if heat is removed by cooling the reaction mixture, the reaction will proceed to the right"
I listened well, but somehow i'm confused.. pls help?
who needs school when you have CrashCourse?
This is what we do in grade 11 in South Africa, 16 - 17 years old.
