11 5 Temperature and Pressure Gay Lussac's Law
Hey! Thank you so much for your videos-they have been extremely helpful for me this whole semester. I have another problem under this same name, but it has two nitro groups and is talking about rotational kinetic energy. Is there any way you could do a video with an example of the rotational problem?
Ok How did you get such a hard sounding problem. It is still easy. Whatever your top number of epsilons is will be shared between your 2 nitro groups. If for instance your number of states is 10e then the 1st nitro could have all 10 of the kinetic energies and the 2nd would have 0. Or the 1st 9 and the second 1 etc. Since the 1st group can go down to 0, there must be 1 more state than you number. In this example, W would =11. The lower energy is the same. Add 1 to the number of epsilons and you have your second W. Whichever one is the last goes on top of your fraction and the other goes on the bottom then do it as I explained in the video you watched. Best I can do. Good luck.
Thank you! I was really scratching my head on this problem and this video finally helped me figure it out.
im so glad Thanks.
Why couldn't we just say 1/3 for the product and reactant then?
the concentration of the profits raised to its coefficient over the concentration of reactants raised. to its coefficient is equal to K. the numbers of reactants and products are not necessarily equal to the K.
thank you!
Thanks. I was able to memorize the solubility rules in 5 mins with the help of this picture.
Me too.
Egipt is not at the equator. It is at the Tropic of Cancer, I think. Thanks for the videos regardless.
Thanks for helping me improve.
the math is not mathing???
Keep going. I hope you have fun with it as you struggle.

Thank you so much! I truly appreciate how you fully explained what was occurring- it helped strengthen my understanding, finally 😅
I'm glad it helped you. Thank you for your kind words.
This was a big help. Thank you so much.
I'm glad
1:30 just as the prophesy foretold, rizz
Good luck this term.
Can you use a cursor or pointer when explaining…beginners are having a difficult time following
I'm sorry. I'll do so in the future videos
This took a bit to process but helped a lot! Thanks 💚
I'm glad.
I appreciate it
I'm glad. Thanks.
this was rlly helpful thx!
thank you.
Super helpful thanks
you're welcome
Omg not the first problem being the EXACT same problem lmao
wow that's amazing
Wow this did not eat
Can I email you a chemistry question ?
what's your question?
Thank you!
thank you
W video
Note to anyone in the future watching this: - The criteria is not that a mineral should not contain carbon, but that it should be inorganic (carbon + hydrogen). Diamond, which is all just purely carbon, is a mineral. - Mercury is not a mineral because it does not have a crystalline structure or a solid structure Edit: grammar
great comment. Thanks
so helpful thank you 🙏
Very helpful
this is beyond confusing still im gonna have to drop this class
oh my god thank you i didn’t get any of the other tutorials and it finally clicked
👍
Thank you sir😊😊😊..from Malaysia🇲🇾🇲🇾🇲🇾
Nice
Where did these sp2 and sp3 hybridisation come from ?
What do I do if there’s a metalloid in the compound ?
A metal reacts with a nonmetal ionically.
Appreciate the help
thanks
Please take this video down!! That’s absolutely WRONG…. Take it down sir. This is NOT correct…

No
Thank you for the video sir.
I can’t emphasize this enough “You are truly a savior!”
I am certain that I would make an insufficient savior. I wish you well in your studies.
thank you! this was very helpful
I'm glad, thanks.
do we have to convert to seconds?
the half-life has to be in seconds.
what would a weak acid look like
you will have a mixture of HA and H3O at the end
Thanks!!
you're welcome
Couldn't have done this without you
I'm glad it helped you.
My feelings EXACTLY! Thank you sooo much!
Where did you get the numbers from?
U help me so much I am in 7th grade learning AP chemistry and you are getting me through it easily
I'm so glad. Congratulations on your hard work.
Thanks! :)
you're welcome.
I had a similar one, but with 13atm for NO and 14 Cl2 with Kp= 7x10^-3 and aleks said it couldnt be predicted. Sneaky Aleks is sneaky.
It sure is. Good luck this term.
Thank you for this video! I was wondering if the sig fics will always be depended on the given K?
no, whatever the sig figs of the reactants will be those of the answer. there are certain rules to follow.
yap
bros just yapping need roxi hulet to post bout this topic fr
Roxi his excellent
