great video. Screw the haters, they will complain about literally anything but have no ability to do anything else. I'm a university student and this helped me
Thank you nice explanation. I may add a few things. bond breaking requires energy because in bound state,total mass of bound atoms are actually lower than total of mass when they are free. so we need to give energy and they take this energy and convert to their mass. Einstein's formula.. I think there are very deep relations down there but everything is nice
Thank you soooo much!!! Just started learning about thermodynamics at university and this has helped immensely would probably not pass if it weren't for you guys
I got it upside down so I recap here: You used 1707kJ to cut bonds. Cutting bonds is less stable with higher potential, requires energy to maintain. And got 1998kJ from making bonds. Making bonds is more stable, releases energy.
The C-H bonds in the reactant are not broken and retained in the product. So even if you consider the bond dissociation enthalpy in reactant, you will have to consider bond formation enthalpy in product and being opposite in nature these would just cancel out.
Thank you, although I have to say this video has a lot of mistakes in the narration, several times the voice says something that is not correct (like in time 8:20 is not the bonds that are broken but the ones that are formed...) maybe you don't care but if this comment has any help for you to get better videos in the future it would achieved its purpose.
Hahah I get it!! Thank you so much!!! I find you better than Sal. I can't stand his uhhh's and the constant repeating of a sentence when he changes his colors. I mean I do love Sal but you're like the sister-in-law that you love more than your brother if you understand.
Would somebody oblige to explain the case of a dimer formation as in Diargon where Electron Affinity is positive. Would H still be negative, i.e. that formation still be considered as releasing energy?
Why is the bond enthalpy for triple C-C bond lower than 3 C-C bonds? Shouldn't it be even easier to sever the last bond than the 1st and second of the 3, since the Cs would be closer together when triple bonded?
Incorrect: I kept getting the wrong answers and its because you are suppose to add the bonds formed then subtract it from the bonds broken instead of subtracting the bonds made.

When her mouse handwriting is better than my pencil handwriting.
Im guessing she uses a tablet but still its really neat :P
@@2030games If you look at 0:23 she moves her cursor to the left to write. So I'm guessing it is mouse handwriting, as opposed to tablet handwriting.
Jeffrey Huang she might have it set to relative and not absolute
@@jeffreyhuang3814 She could have moved her hand
@@meatsupplies5282 😁👻
she talks cute omg!
why
She wear glasses
Awesome video. You guys always make quality stuff.
Nice video.Helpful to me I'm in class ix .This video topic make me very easier.
great teaching skill.full clarity.
Thank you so much and really good 👌👌👌
Thankss!
Nice video. Explained succinctly, pace is excellent,
Handwriting is so beautiful
you saved me thank you
Thank you found this really helpful, I'm a first year student and it's nice to understand it the way you've explained it keep it up👍🏾👍🏾
Hello
this was a very helpful review for me, I sure appreciate this
Thank you so much,it was really helpful
I finally get why I was getting my answer wrong....I was calculating ALL of the bonds and not just the ones that changed

This is gen chem 1 ali, chill
At what Bond disscociation Energy is a bond considered stable? Is 40 kJ/mol a stable bond?
your handwriting and organization are high key way better than Sal's
Whoa, shots fired
Great video, helped a lot. Thank you!
I really had to force myself to stop focusing on how cute she talks and rather listen to whats she's talking about.
i get it man
bro is down horrendous 💀
Thank you soooo much!!! Just started learning about thermodynamics at university and this has helped immensely would probably not pass if it weren't for you guys
very clear thanks

btw why aren't the C-H bonds in reactants taken into account?
The C-H bonds in the reactant are not broken and retained in the product.
So even if you consider the bond dissociation enthalpy in reactant, you will have to consider bond formation enthalpy in product and being opposite in nature these would just cancel out.
Awesome writing
Thanks alot. I could never understand the numerical by myself.
it is the amount of energy required to break all bonds in 1 MOLE OF A SUBSTANCE. but it was a nice video :)
its a really good video , helped me a lot..
i only watched this because her voice is cute
I love this explanation and your handwriting is amazing! :-)
Like who have biggest thermodynamics chapter in 12th...I have 45pages...
Thanks for teaching me something new😍
I reckon you did an amazing job whoever you are !
thanks

great
hi isnt the c-h bond 8 bonds ?
Lovely.... 👍
Dont u have to balance the rxn?
Hahah I get it!! Thank you so much!!! I find you better than Sal. I can't stand his uhhh's and the constant repeating of a sentence when he changes his colors. I mean I do love Sal but you're like the sister-in-law that you love more than your brother if you understand.
best video ever
Do you also sell propane accessories?
Bond formation is an energy absorbing process ri8 ? I m confused
Bond formation releases energy... Right???
Because of overlapping of atoms (electrons)
Would somebody oblige to explain the case of a dimer formation as in Diargon where Electron Affinity is positive. Would H still be negative, i.e. that formation still be considered as releasing energy?

I prefer sal
joe bloggs sal is GOWD
Anas way more
kickboxing chemistry can be a combo
What do you mean by '1 mol of a bond'?
Maybe she means "the number of bonds within one mole of a given molecule"? I'm honestly not sure.
I hate chemistry. Its so frustrating
why is energy released when a bond is formed? I can't conceptualize it.
because the bonded molecules are now in lower energy state, molecules are bonded to do that (to minimize their energy and become stable).
A beautiful vedio contains a beautiful handwriting and a beautiful voice with a beautiful explanation
bro its video not vedio.
She has a pretty voice and handwriting
what if it's in a soild form?
popcorn xd
did you just write 'hess's law' instead of 'hess' law' 😮

pretty
Incorrect: I kept getting the wrong answers and its because you are suppose to add the bonds formed then subtract it from the bonds broken instead of subtracting the bonds made.
I don't get it lol
LOL
haters gonna hate..
really good handwriting, Her voice lowkey annoying thoo
bro
u mean u cant concentrate. yeah me 2

This woman sounds like the woman from that channel about ADHD. Can’t remember. She calls her followers “brains”
brother what 😭

This was super helpful, thank you!
