- I went over Kinetics (rate laws, concentration vs time, reaction order, collision model, Kinetic Molecular Theory, Maxwell-Boltzmann curve) and Intermolecular Forces (London Dispersion Force, Dipole-dipole Attraction, Hydrogen bonding, Ion-dipole force, IMF and solubility, covalent network structure, Ideal Gas Law, deviation from ideal gas) and Chemical Bonds (ionic, covalent, metallic)
I’m really hoping you’ll be able to upload the other units in time for the ap exam. However thanks so much for these as well!
For problem (a) at 1:26:21, could you directly use n=c*v to calculate the number of moles? I didn't quite catch the use of dividing each side by volume
No you can't directly use n=cV. For this formula, the concentration has the unit mol/L. But the concentration given in the question has g/L as its unit. That's why I divided both sides by V, so m/L has the matching unit of g/L.
@@academic-coach-youhyun Ahhh I see I see. Another question I have then is for 1:56:00, do we need to know the formula pH=pKa+log(F/HA)? Thanks!
@@krazedsg4286 you mean [conjugate base]/[acid] right?
@@krazedsg4286 Anyway, this equation is on the formula sheet. you don't have to memorize it
@@academic-coach-youhyun Okok! Thank you so much😭
appreciate you girllll💖💖💖😔💗😔 ... hope your are doing well
@academic-coach-youhyun What is the difference between ICE, ICF, and IMF tables??? I am on a tight line for the AP. By the way, I really appreciate your videos.
I(initial) C(change) E(equilibrium) is used when the reaction eventually reaches equilibrium. ICF(final) is used when the reaction goes to completion. To be honest, as for calculation you can use ICF instead of ICE. This is just an easy way for doing math and it's not some Chemistry concept. You won't get points off in the AP exam for using these two interchangeably.
I've not heard of IMF though.
@@academic-coach-youhyun okay ✅ BTW your video title says IMF, that is why I was asking, maybe you want to change it so that there is no more confusion about it.
@@academic-coach-youhyunThank you very much. I appreciate it. Very helpful info, plus you and your vids are amazing. 😻 ❤😊
Or wait IMF was intermolecular forces? Okay sorry I was confused. Got it now thanks 🙏
Can i have your slides please
Whooooo
