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

[@kalielaine2328]

The more you learn about chemistry, the more you realize what you previously knew was wrong.

[@georgeabreu6392]

Kali Elaine That quality is true for all knowledge though.

[@MohammadBilal-xt2xh]

Basically an outcome of every science course I have taken haha.

I love how Hank slips in philosophical life advice while ostensibly talking about science. -- "Equilibrium isn’t about staying the same all the time; it’s just about keeping your balance as your circumstances change."

[@KodiaxeMusic]

"Perfectly balanced, as all things should be." -Thanos

[@leewalden3061]

the beginning of this video is actually infinity war. lmao

Thanos is a master chemist

[@TheMrzippie]

I have a test about this in like 2 hours.

[@theduh1011]

Phuong Tran I got a B somehow, so I guess it all worked out well in the end!

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

[@Fenrick]

hey there cutie

[@aniakonopka8958]

I’m revising this for my GCSE’s nahh

So how did u do for your A levels

[@VarshiPyndanna]

Dear Crash course, I'm in my final year of schooling and I'm actually not sure when exactly I started to watch these videos but y'all have been incredibly helpful throughout my years of school. From the bottom of my heart, thank you so very much ❤️

[@LucyOswinSpence]

My teacher spent around 4 lessons trying to explain this to me and she still failed, you've done it in ten minutes! Thanks guys!!! :D

[@UmarTahir]

It was the greatest day of my life when my Chemistry teacher showed us a lesson from my favorite youtube series. So awesome.

[@willbanyard3480]

Cramming for chemistry tomorrow?

[@flow1465]

Science is the only subject which allows you to use your imagination, don't spoil it by cramming.

[@rockercaterrorencountered4924]

Science is the only subject that allows you to use your imagination? What about English? Art? I like science as much as the next guy, but that statement was more than a bit off.

Jokes on you Chem quiz, this KZbin channel exists.

[@2berrykool]

seriously thank you for your videos I got an 88 on my last exam where the average was at a 68... next exam t-minus 2 weeks and final the week after

[@twaal22]

Wish you the best!

[@sherripy3932]

I swear it is not even funny how much your videos are helping me with my chemistry class. I'm studying for my last test (tomorrow) and looking over the homework packet(which i did not do) i realized that I know absolutely NOTHING!!! But watching these videos make everything a LOT easier! I cannot thank you enough for making these videos! I am so grateful to you!

[@khhtutor]

Applause and applause. SAT chem teacher from Taiwan🇹🇼

[@waynasattar2991]

So much to say: 1) I love how there's a variety of classes on Crash Course. 2) Bless Hank for making me less stressed with all the sarcasm and light jokes. I love how he does that. 3) A request: Could you please do a video on the Contact Process for manufacturing Sulfuric Acid? THANK YOU

[@sanahita9678]

I have a major Chem. mock test tomorrow, and I'm resorting to these videos as my final study session! xP

[@shirubionicle]

+Wishbone K. Luck Good luck man

[@pete8420]

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.

[@22453790]

This cannot have come at a better time. I have a chemistry test on equilibrium tomorrow. Thanks soo much crashcourse

[@SuperSox97]

I applaud you two for having a debate so intelligent and devoid of hostility. I found it very interesting to read through it, and I'm glad to know that there are people on the internet that can intelligently discuss subjects (especially ones like global warming and starvation) without raging at each other.

[@kashshk845]

i love how im casually revising, watching crash course to actually understand chemistry and then obviously ONE DIRECTION, why dont them lads leave me for a second to focus IM SHOOK

Hey Hank, you know what would be awesome? If you could do a series on Physics *insert excitement*. Your chemistry videos have helped me so much!

Not sure why this popped up in the algorithm. I'm not studying chemistry. I've never even taken chemistry. I'm not even in school, graduated years ago - business major. But I watched it anyway, and I think I learned something new.

[@shirubionicle]

why isn't there a crash course physics channel?? this is a question ive been asking since da beginning of time XD.

[@JTan-wu7wg]

+Shriram Raveendran Don't know. Probably because CrashCourse tries to fit everything in around ten minutes. Physics, I assume, needs more time than around ten minutes.

[@JTan-wu7wg]

Gunbnelch Maui Yea. I'd usually watch CrashCourse in junction with Khan Academy and Bozeman Science.

[@shereitograce7844]

+Shriram Raveendran I would totally watch that so hard.

[@airro3672]

Physics = Brightstorm. Chemistry = Crash Course. Biology = Bozeman

[@arousedsquirrel2429]

+Gunbnelch Maui Khan could explain what he waists 10 minutes on, in at least half that time.

[@tourmaline2228]

when you have a online test in less than 30 min and crash course is your only hope =]

[@lazyboy395]

The best way to study for a tea you have RIGHT tomorrow is to listen to a KZbin 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

[@apsanders9359]

Thanks for the video and all the other awesome videos! However, there is an issue with the concentration vs time graph around 3:15. The change in concentration should be the same as the stoichiometry ratios. I realise the y-axis has no scale but I think it is still a relative scale and probably needs to reflect the 1:3:2 ratio of the equilibrium equation.

[@parissitzoukis2919]

this is fire 🔥 🔥 damn love it

[@seamie6644]

Well, Hank talked about pressure and temperature can change the side of the equilibrium reaction, so how about volume? does it affect too?

[@alysiastringer5610]

volume is the same as concentration which he discusses at the start...

[@GhastlyDesigns]

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). :)

[@seamie6644]

GhastlyDesigns how can I forget about Boyle's? So stupid of me! Thanks anyway :)

[@GhastlyDesigns]

No worries :3
