Re: What exactly is 3/2RT and when do we use it?

Do you just use 5/2R when it is at constant pressure?

Re: Derivatives and Integrals

I feel like we won't need to do any calculations with derivatives. I think those equations were given just to help our understanding.

Re: Energy

Since neither energy nor matter can be exchanged in an isolated system, the energy cannot change and will remain constant.

Re: Constant Pressure/Volume

So if pressure is not given, can we assume that it will remain constant at 1 atm?

Re: When to Use PV=nRT

PV=nRT can be used to relate Kc and Kp since you can use it to convert between partial pressure and concentration.

Re: Kc and Kp

Kc can be used for both aqueous and gasphases, but Kp is for gases since you use pressure. And the ideal gas law can be used to relate Kp and Kc

In order for the interaction to be strong enough, the Cl's must be on the same side and must create a net dipole.

Re: Determine Lewis Acid

One thing to look for is if something has a lone pair of electrons, it would be a Lewis base because it would donate those electrons.

Re: Disperson forces

larger atoms have more attractive forces between them because they have more electrons, so they they will have stronger dispersion forces holding them closer together and will therefore be liquid at room temp rather than gases.

Re: Electronegativity

Electronegativity decreases as you go down a period because the atoms have more shells of electrons, so the valence electrons are farther from the nucleus. This means that the pull on the electrons is not as strong as in the atoms closer to the top of the period.

Re: formula units [ENDORSED]

I was unsure about what the problems meant by formula units as well, but I just treated it as sort of a synonym for "molecule". So one of the problems asked how many formula units of a compound are in 5.15 g, I just found how many molecules would be in 5.15 g, using Avogadro's number.
