Distinguishing Nucleophiles

Hey, I was just wondering why on Ch. 4 review problem 1 they distinguished F as an electrophile yet in the reading they said F was a nucleophile. Is it now an electrophile because it wants to have the octet or did the book make an error ?

When determining the strength of nucleophiles, does it depend on polarization or is there some other way of determing which nucleophile is stronger?

intermediate species

Hey i was just curious as to when we would know whether an intermediate species needed to be added or not and how to determine which species gets added.

cell diagram

Hey I'm having trouble figuring out how to write a cell diagram How do you determine which one goes on the left and which one goes on the right? Also, do we include the salt bridge elements?

When do you use w=-p delta v as compared to just w=p delta v. Does the negative have to do with reversible and irreversible reactions or is it compression and expansion?

Hey, while I'm going through the problems, I find it hard to keep track of when to use each equation. Does anyone have and tips on how to keep track of what equations you use under specific conditions?

Internal Energy

How can you tell whether to subtract or add in order to get the change in internal energy? In question 5 you added them but in question 7 you subtracted.

Naming Formulas

If we have lets say tetraamminediaquacobalt(III) bromide, and we are putting together the formula, does it matter if we put the ammine after the aqua or are there specific rules for the order? also can we put the aqua in the (OH2) form or does it need to be (H2O)?

Re: Cis and Trans Dichloroethene

For the chlorine, how in the cis they do not cancel but in the trans they cancel, does that just determine whether it is polar or nonpolar or does it also relate to the charges and repulsion?

Heisenberg v. Schrodinger

I know that Heisenberg's equation deals with the uncertainty of the location of the electron with its mmovements and how Schrodinger's equation squares the wavefunction to find the probability of finding the electron but what is the difference between them and when do we know when to use each one?

Multi electron atoms

With the multi-electron atoms, it gives (q1 x q2/r) to get the potential energy without shielding, but does shielding happen between s, p,d, and f or is the energy different between different s,p,d,and f levels as well. For example, if there was 2p and 3p would we use that equation or would it just ...
