[@Silents30]

I only have a few hours to study, and you make everything so clear and fast. You are my new best friend.

[@MakerBayfield]

put on 0.75x speed, its perfect

[@kennys3095]

Thank You. This lady can cover as many concepts in just 5-6 mins as any other tutor would do in 20-25 mins :) LOL!

[@SnowBlossom]

I actually like how short these vids are. It means I can pause, rewind, and watch a large number of them in one hour rather than a 3 or 4 16-20 minute videos.

[@adarshchandel6022]

How much have you changed after 6 years

[@lilgamer1795]

THANK YOU VERY MUCH!!!!!! without your videos i would've been failing my school exams , great job bright storm and keep it up!!

[@kikoritax33]

I love the fact she speaks in a fast pace. All my teachers speak really slowly and its really difficult to get what they are saying, everyone get distracted so fast~~ Thx, I love your videos!!1 :D

[@christinabaden5213]

Great videos, so helpful! The speed and clarity are fine. Thank you for sharing these.

[@goamongmadpeople]

Actually, it is quite easy to understand her at the rate she is speaking. Great video, thanks a lot.

[@fairytail6804]

Awesome vids. She's pretty hot talking science, but I like her faster talking. Get to the point faster (although im not taking notes)

[@violinsheetmusicblog]

Beautiful, never disappoints.

[@alan54130]

thank god for these vids!!!! You are a life saver!!!!

[@tinula]

you explains very clear manner even i couldn't get some parts in mother tongue

[@aaronck1916]

guys you are lifesavers! great vid..

[@singeress2]

Great video, Thank you!!!

[@melaniehellam1512]

Thankk you soo much for your help! you assisted me a lot with my studies..God bless :)

[@DionPaz]

I love her, she always saves my day :)

[@troublemaker0001000]

I aced my test thanks to her! thank you Brightstorm

[@melissaflores3336]

Thank you i learned a lot

[@FungSit]

I like the speed of her speech, condensed information, very informative!

[@chaccco123]

@KatsAndBees the graph shows the reaction from Reactants --------> Products in a Froward Reaction. When the energy of the reactants is higher than the products, it is an Exothermic reaction. Take note that when you subtract the 2 numbers (forward reaction) - PRODUCT- (minus) REACTANT, when the difference is negative, it is an exothermic reaction. If the difference is positive (+) its an endothermic Rx. The graph shown in this video is an exothermic reaction ( the reactant energy is higher).

[@shaketlovet]

Thank you!

[@sccm100]

Wow this was very fast and very good

[@jimparsons6803]

Interesting. Thanks. Brings up fun memories. For those that are interested in organic. See: 'Organic Chemistry,' by Morison and Boyd, or for those with advanced tastes, Advancd Oranic Chemistry by Fieser and Fieser.

[@beinganangeltreon]

The rapidity keeps me alert

[@lfcforever]

Yes, you can cross out species on the left and right side ONLY IF they are produced on the right and consumed(used up) again on the right. They are what we wanna call the "intermediates". hope that helped.

[@spiritedmaru]

@pSychOAtDawn -pokes 3:30+- If its not given you will probably have data to determine which steps are "fast" and which are slow. Or may have to acquire data through experiments.

[@zain19]

Best way is to write everything down while listening,pause if you get behind. Afterwards go back and watch again,start making side notes.

[@LOLWTFBBQz]

As a half-deaf American attending college and majoring in chem, I have a countless barrage of Indians who can hardly make sense when they speak. This woman does an amazing job and no one should complain.

[@JetsCB]

veery helpful!!!!!!!!!!!!!!!!!!

[@HBpencilx]

@Hedonistic21 she is quite clear in her speech though

[@purplefire5]

@KatsAndBees if the enthalpy or delta H is negative it is always exothermic

[@00terrorist]

thanks yo

[@shafsteryellow]

The speed keeps me alert i'd be bored otherwise GREAT VID

[@sciencelessonsinsinhala1540]

Wow 👍

[@trevoreaton2358]

how do i take it off fast forward

[@NeelSandellISAWESOME]

I put these videos on 1.5 speed lol.

[@Super7amzah]

شكرا

[@purplefire5]

@zacmiley12 we can assume this because the reaction takes the most time (it's the slowest) which means the it take the reactants a lot of time to overcome the Ea (activation energy) just remember high activation energy means reaction takes longer, smaller activation energy reaction takes longer

[@ashrox007]

@zain19 she naturally talks like that. Check out brightstorm's website and you'll see.

[@chyeahhhhhh]

it's not that I don't understand what she's saying, I'm just impressed by how fast she talks. So. fast.

[@ggmm117]

We have to make our own reaction mechanisms. and hope it works out.

[@Snow_Pulse]

Then they would either give you a graph to find out. They always have to give you a way to tell if its fast or slow no matter what. TRUST

[@SpasticWire]

hell ppl im from India and i think she speaks just right.....and btw do you have a video on nucleophiles,electophiles and all??

[@ZoeeexD]

@KatsAndBees if the delta h comes out negative

[@xkillingxtime]

Isn't chlorine gas also very unstable since it is also diatomic?

[@LOLWTFBBQz]

Actually, growing up as such had me in speech therapy for the first 14 years of life due to fact couldn't understand normal Americans. Why it is rather difficult to understand a foreign accent, much of that comes from the individual being unaccustomed to having to make a conscious effort to decipher what they're actually saying. It's a skill that is able to be learned if needed, most just chose to complain instead, mainly Americans.

[@WAWAWAYEN]

Ea for the rds, why the 2NO + 2H2??? coz in the elementary step given, 2h2 dont exist at rds....

[@KatsAndBees]

how do u knw if its an exothermic rxn tho

[@HBpencilx]

@lebron15594 i think most of the times u will b given the elementary steps

[@meryemlahbara9669]

I Love You 💕❤️😘

[@joudisinjab8457]

if it werent for your videos i wouldve failed my test. thank you

[@aaronck1916]

I just have one question though.. in the reaction rate laws you guys said not to use the co efficient.. but at the end of the video you guys say we can use the coefficient.. please explain.. :s

[@PepsiT98]

EXACTLY!!!!!!!!!!

[@superJohnnydeppfan]

because we know the steps that the reaction goes through and we can use slowest step to determine the rate. as opposed to the other method which uses expiremntal values to determine the rate. it's just two diffrent ways.

[@KatieP574]

can't handle the amount of times she says 'reaction'

[@kingkrazy0wns]

She speaks at the perfect speed, maybe it's just because I'm a New Yorker and we talk fast.

[@reardelt]

or rewind and play again.

[@ibrahim2ibrahim]

i think she should still divide them up into parts, it just feels like such a waste sometimes...

[@bb4465]

does anyone how to recognize the catalyst and the intermediate? since both do not appear on the final equation. idk how to distinguish them TT^TT

[@abhisheknoba]

B B I think catalyst already exist even before the start of the reaction, though intermediate, as written on the whiteboard, generated in one elementary step and consumed in another one. It sounds logical to me. Please correct if I am wrong. Take care !!

[@IAmDJVie]

Bringing this back around to the original comment; I do not know where @Hedonistic21 is from, so I cannot say for sure that he/she chose to be difficult about her accent. And, even if he/she were American, it may be that they had not come across this subject before, and were having difficulty comprehending it due to the seemingly foreign terminology. Even then, he/she had the option of replaying the video, so I suppose you're right... They were probably lazy. :P

[@TheDiora101]

What if it didnt say fast or slow?

[@oceanceaser44]

there is a pause button man, thats the point

[@zain19]

Its not her fault because youtube don't let them have the each video for more than 10 min

[@jessiejd5330]

shout out to snoddon

[@bhatzahid3573]

put it t0 0.5 speed

[@lambanmartyr]

listen faster or use the pause/rewind button

[@SniPeXBasiKs]

great tutroial, but the insanley fast talking and stuttering is quite annoying at times. I know that there may be time restrictions. but why not just make a part1 and part2

[@LOLWTFBBQz]

you need to think faster

[@riloenyosi]

Simple solution is just listening faster

[@adreniln]

@zain19 But yet this video is only 6 minutes...

[@lfcforever]

CORRECTION to my earlier post....* consumed on the LEFT,,, (not right)

[@IAmDJVie]

Not everyone on here speaks English as a first language. And given that these videos are available globally (or didn't you think fast enough to realise that?), you should know that the audience is much larger and way more diverse than what you are used to... meaning that not everyone (myself included) can keep up with this particular American-English dialect. ~ And she does tend to skip syllables when she speaks, so that might be another hindrance to some. Just FYI ;)

[@sanniebonbon]

the heck are you? noone was talking to u

[@helensmonica]

but i thot oxygen never existed as single atoms cos it doesnt have stability

[@joemchang]

Now I am so fucking slow

[@raitaleo]

Her quick talk is charming... I don t get a thing of what she says but she s a babe..

[@IAmDJVie]

I completely understand. But, you seem to forget the fact that you are American. Your brain has adapted to understand your regional accents without much effort, because the phonetics are so much alike. Here's a parallel argument; an American-born person with immigrant Indian parents, will easily understand an Indian professor who cannot speak perfect English. Why? His immigrant parents have probably exposed him to their culture and languages, so his mind is well accustomed to "Indian English" :)

[@drewbauer2860]

this one was 6 minutes....

[@andrewharlan8256]

FFS stop saying umm

[@murraymj1995]

This video was 6 minutes

[@amberchia7708]

She talked toooo fastttt

[@leduyluan1994]

she speaks too fast to me :((

[@mookieboo2965]

you talk to damn fast

[@cobaltv7884]

+mookie boo You don't know how to use "too" correctly...

[@mookieboo2965]

you talk to fast!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@mookieboo2965]

oh I forgot ----you talk too damn fast !!!!!!!!!!!

[@EdwardCullensMayo]

@Hedonistic21 you need a faster brain

[@sanniebonbon]

She Talks too fast :(

[@Lyrics0for0you]

Ur attractive cant focus!!!

[@dragon_bro_0]

0:51 put on x.25 speed. LOL

[@josejones8837]

my GOD slow down women!!!! she is really good at her stuff but...slow down

[@1413088]

you are beautiful...in a non-creepy way...

[@19abhishekbanerjee]

Good, but the Indian teachers are way better than her.If this lecture was taken inside a classroom , then there sure as hell should have been interaction between she and her students. Its not a tailored made speech she is up with.And FYI, catalyst is a substance which alters the rate of reaction , it does not necessarily increases the reaction speed, there are negative catalysts also available which hinders the rate.

[@natelian79]

Actually, a catalyst is a substance that increases the speed of a reaction by lowering the activation energy. There are no such things as negative catalysts; the thing you are referring to is an inhibitor which decreases the speed of a reaction by increasing the activation energy.

[@miguel-angelgarcia9367]

Nathan Lian You forgot to add "BEEOOOOTCH!" at the end of your comment. You explained that very well

[@zondrah89]

she's good, no need to compare. my only criticism would be that she speaks a bit fast for someone new to the subject matter.

[@Bandtx]

Oh shit you got bitch slapped across the face, how does it feel? Also, indian teachers suck, their accent is too deep when they speak english.

[@Silents30]

I only have a few hours to study, and you make everything so clear and fast. You are my new best friend.
