yes lone pairs affect the pulling

105012653 1F

is it because there isn't a partially negative charge?

105012653 1F

if dipole moments cancel out then the overall molecule will have zero dipole moment

105012653 1F

yes all substances will have london forces.

105012653 1F

Not quite sure about this either..

105012653 1F

Yes the closest to stable would mean zero formal charge

105012653 1F

also was confused about this question..

105012653 1F

"Oxygen will want to gain or receive electrons badly making the ionization lower" im lost on this concept, can you further explain?

105012653 1F

I did the steps but I still got something different...

105012653 1F

^^ agreed

105012653 1F

^^ I had the same question.. still lost on that

105012653 1F

this makes so much more sense now... thanks!

105012653 1F

I had trouble with this question too... great explanation!^^

105012653 1F

I don't really know whether it'll be given on the final, but I don't think hurts to memorize pH = -log[H3O+].

105012653 1F

They are the same; you should be able to use all names.

105012653 1F

Sorry, I'm kind of confused; what exactly is an oxidation state?

105012653 1F

What was that joke about sodium again?

Na, nevermind I forgot it.

105012653 1F

In what scenario is it okay to break the octet rule?

105012653 1F

What are formal energies used to determine?

105012653 1F

What is the best way to study conceptual questions?

105012653 1F

It means the lowest energy. Atoms and molecules, if left alone, are in their ground state (lowest energy). Therefore, as I discussed several times in class, we can figure out the electron configuration without needing to memorize them. By extension, how would the electron configuration be for excit...

Alma Flores 1D wrote:The 4s orbital has higher energy then the 3d orbital. After the 4s is completely filled, 3d is lower in energy than 4s.

Although I know this to be true, is there an explanation as to why 3d is lower in energy than 4s only after the 4s is completely filled?

105012653 1F

If we're finding the electron configuration for, say, an ion with the same amount of electrons, would it also follow the same rule?

105012653 1F

Has anyone found any other resources outside of class that is useful for preparing for the test? Like any practice exam/test problems? I think using the course reader and taking advantage of the Peer Learning Sessions are really helpful, especially since my friends who had the class before really r...

Is there a trick in doing them faster?

105012653 1F

No because it was either be completely used up or some left over and two reactants cannot limit one another

105012653 1F

Also confused on this

105012653 1F

What are the uses of Avogadro #? What's an example we would use it in?

105012653 1F

Could you go in more depth? Still not sure too

105012653 1F

Is there a more efficient way to balance out equations? I know the fundamentals of balancing it's just tedious sometimes. What's a trick in doing it faster?
