chad you are single handedly saving my gen chem II grade. and you'll probably single handedly save my organic chem grade next semester. so thank you :)
Everything you say in these videos are very well articulated and help me recap well for finals. I hardly understood this at first when I took this chapter back in February and you have helped provide examples and explain concepts well.
You're an amazing person. God Bless your soul. I have a final Friday for gen chem 2 that I was stressing over, because I need to score 100% in order to get an A in the class and get a 4.0 for my second semester in a row (partially thanks to you) and your videos just make everything click, they are so clear and so helpful. You're truly helping the next generation of students pursue their dreams, and I am ever grateful!
Chad I know this is a Gen Chem video but I just wanted to say thank you for helping me pass ochem! You were in a sense my tutor somehow you had the answers to my questions! Your videos have helped me and my friends so much and everytime I hear someone struggling with any type of chem I recommend you! Thank you:)
Hello, I would like to ask why some formulas for bp elevation and fp depression incorporate the van't Hoff factor while others don't? I can't understand why some remove i because the former and the latter produce different answers. Thank you!
Hey John, do you have an example? Likely if it is a non-electrolyte the Van't Hoff factor would be 1 and so may be left out of the equation in this case.
Hi, Chad. Thank you greatly for the wonderful explanation! I have a question, however. If we are solving for Kf, would we divide the delta Tf by ( i * molality)?
Because Osmotic Pressure is a special case of the Ideal Gas formula. If you look closer to the Osmotic Pressure formula, you notice it lacks the n in PV=nRT, that's because n/V is molarity, or in this case, the overall molarity of the gas. Osmotic pressure simply calculates the pressure that water exerts on a surface or container if it was measured in its gas phase.

Thanks for saying so, Emily - glad you found the channel!
Your videos deserve a lot more credit. You do an incredible job to simplify complex concepts, the examples are truly incredible!
Thanks Lula and truly glad you're finding these helpful!😊
Hi Chad, your shirts give me so much life! Reminds me of the big picture when I am studying.
Excellent - and a great perspective!

Glad the channel is helping you - get that A!
i've watched 3 of your videos so far and what's crazy to me is that i understand everything so well for the first time :') appreciate u!!
That's excellent - Keep enjoying and learning!
great video but i was wondering if you could talk about volatile/volatile and go a little more in depth about raoults law - THANK YOU!
The more I watch this channel, the more I wonder why this channel doesn't have more views/subscribers!
If only I was as good at marketing as at teaching... :)
What is the van't Hoff factor of MgSO4 ?
that would be 2 as MgSO4 dissociates into Mg(2+) + SO4(2-)
Am so grateful thank you so much
You're very welcome
If u multiply the Vant Hoff factor at the end, it wouldn't work for a solution with two dissolved salutes.
This infinitely more helpful than my class.
Excellent!

Glad the channel has been such use to you, Jerrymvrtinez - thanks for recommending to others, too!
Why didn't the BaOH have the baby equal to 3since the hydroxides are 2

Thank you very much for your beautiful lesson. In particular, I finally understood Raoult's law.
Hello from Italy
You're most welcome and thanks from USA.

Exactly right Chelsea, and don't forget the negative sign also!😊
@@ChadsPrep Thank you!
@@chelsea9013 Very welcome.
hey chad!
for vapor pressure depression, are we lookşng for moles of solute or moles of ion when we try to find ntotal
Is this for the mole fraction? In which case it would be moles of solute + moles of solvent
Thank you so much omg i wish you were my prof lol you explain it excellent
Happy to help!
The osmotic pressure formula is quite similar to the ideal gas formula.
Because Osmotic Pressure is a special case of the Ideal Gas formula. If you look closer to the Osmotic Pressure formula, you notice it lacks the n in PV=nRT, that's because n/V is molarity, or in this case, the overall molarity of the gas. Osmotic pressure simply calculates the pressure that water exerts on a surface or container if it was measured in its gas phase.
wheres chapter 12?
Thanks alot you saved me😢❤
Glad the channel helped you!
Love ur work ❤
Thank you so much 😀
You are awesome
Thanks, Elaine!
I wish I found you channel sooner, my semester was half hell for no reason 🥲
Glad you found the channel, Haylee - Sorry it wasn't sooner!
