Professor Organic Chemistry Tutor, thank you for a short and sweet video/lecture on Graham's Law of Effusion in AP/General Chemistry. According to the history books on Chemistry, during World War II, Graham's Law was applied to a rather complex chemical problem. It became necessary to separate U-235, which is fissionable, from the more abundant isotope of uranium, U-238. Since the two isotopes have identical chemical properties, chemical separation was not feasible. Instead, an effusion process was worked out using uranium hexafluoride, UF6. This compound is a gas at room temperature. Preliminary experiments indicated that u-235 could indeed be separated from u-238 by effusion. This is an error free video/lecture on KZbin TV with the Organic Chemistry Tutor.

This man is just showering us with constant updates and I'm loving it

[@garrettmateo3653]

i realize I am kinda off topic but do anybody know of a good place to stream new movies online ?

[@kamarileonel1276]

@Garrett Mateo lately I have been using Flixzone. You can find it by googling =)

[@tracetate2832]

@Garrett Mateo I watch on FlixZone. Just google for it =)

3 years ago and it's still very valid Thanks for saving lives organic tutor🙏

[@nageshyadavbommu8350]

This is what I was planning to learn tomorrow thank you organic chemistry tutor........

[@tipsprince8026]

I love the way of you.. I mean no matter what you keep uploading videos .. Love you bro it helps me a lot

[@bukolaadekanmbi9795]

This man just helped me in doing my chemistry assignment

[@teamcherzelcamino4154]

Thanks to your videos.I learn a lot especially chemistry.

[@mira-image]

this, as well as your other video on graham's law of effusion, really helped me! i was strugglign to tell when i needed to use the t1/t2 = root m1/m2 and when i needed to use r2/r1 = root m1/m2 for a question on finding t, but after watching and rewatching these videos (As well as reading from a few other tutorial websites), i've come to understand that it depends on whether the volume of the two gasses is the same. if it's the same, use t, if it's different, use r to solve for t.

[@jazzminemungai]

hi what do u mean by using r to solve for t if they are different ,how?

[@mira-image]

@@jazzminemungai I'm sorry, I learned about this topic 5 months ago and it's now left my brain completely and I have no idea now XD That's the beauty of cramming amirite.

You’re the best keep it on ❣️

[@marwincoronel767]

Actually the formula in the thumbnail is not correct it’s supposed to be R1/R2=square root of M2/M1 cause the molar mass of certain elements is inversely proportional to its rate of effusion, just sharing ya know 🥰✌🏼

[@aswin8063]

Yep .. infact that's why I even opened the video cos it was given wrong

[@gamerboss8445]

Uh it still same

[@gamerboss8445]

Caus it doesn't matter whether it's up or down but it has to be inversely proportional

[@JoshuaNkandu]

It's the same thing🤦🤦 geez

[@NesKape15]

thx

[@dorismeliwane1242]

Amazing..this helps allot.. 👍👏🙏

[@afnanbajwa1965]

Hi I have a question how do we know which one to put in each formula. I mean how do we know which gas to put above and which to put below or does it not matter? urgent hv an exam on monday

[@mirandazapata9691]

they are indirectly related. Whatever is on top on one side goes on the bottom on the other side and vice versa

[@elileoci9173]

@@mirandazapata9691 thank u lol

[@Chivende]

​@@elileoci9173 how do I know then that this is supposed to go on top

[@zivyinon4884]

Great vid. Thanks! Do u know if the effusion rates changes if the ratio of mols is diffrent from 1:1? Like if i got a ratio of 2:1 does its effect the ratio?

[@sabarishkumar5612]

Sir pls upload folding and symmetry in circuits sir

[@EddieRogiat]

How did you get the molar mass. Sorry I'm a bit confused

[@MichaelDubuc-z7e]

This should be R2/R1 = square root of M1/M2. They need to be flipped.

Have u seen 'The Doctors' 😅

[@natnaeltadesse7585]

Good explanation

[@OmoleBola-qf2eb]

How will i know which gas comes first

[@jetbean7901]

The formula written on the thumbnail is wrong.

[@arc9171]

noticed this too, its at top of google search as well

[@actual.education]

@@arc9171 yeah this is a HUGE problem - please fix!!!!!

[@TalentedPrecious]

50 cm cube of ethane effuses in 10 seconds what time will it take for 25 cm cube of carbon IV oxide

[@dizzy8175]

Wrong equation at video start. It brings up the wrong equation on google images because of this video. Having the top search result for Graham's Law, and having the subscripts wrong, is pretty bad.

[@natashanzala2198]

Thank you so much 😍

[@arc9171]

PLEASE PLEASE PLEASE FIX THE THUMBNAIL! ITS THE FIRST RESULT ON GOOGLE SEARCH AND IS EXTREMELY MISLEADING!

[@AD-wg8ik]

Change the thumbnail it’s wrong

[@arnavverma2461]

The thumbnail shows wrong formula, pls fix that

[@innocentabae1118]

It's lovely.

[@abigailmellor9973]

the thumbnail is confusing me and i'm not sure which way is right

[@aparnachowdhury445]

The process he shows in the video is correct

[@aparnachowdhury445]

The thumbnail is the mistake
