Re: Difference between Lewis and conjugate acids and bases

Does the label of the compound switch from Lewis acid to conjugate base when the reaction flips such that the name depends on which is on the reaction or product side.

Re: bronsted acid vs. lewis acid

Because the definitions differ a little bit in that one is broader than the other, can one be a Bronstead acid without being a Lewis acid.

Re: Naming the Shape

I think we have to memorize the bond angles for the structures we were shown in class. I believe we're also expected to know how the angles are affected by lone pairs.

Re: Ions and Exceptions to the Octet Rule

Elements in the third period and up can have an expanded octet because they have access to the d-orbital; so there are many elements besides copper and silver that serve as an exception to the octet rule.

Re: Formal Charges on Midterm

I don't think you necessarily have to write out your calculations for the formal charge but it's probably safer to write the number next to each element.

Re: s, p, d, f

Orbitals are the regions of space in which electrons are most likely to be found. Each orbital is denoted by a number and a letter in which the letters (s,p,d,f), describe the shape of the orbital. An s orbital, the first energy level, is spherical and has no nodal planes. A p orbital has two lobes ...

When balancing equations I find it helpful to list out the different elements on each side and tackle each element individually as I go. I re-write the equation with the coefficients I'm trying in order to keep my work organized so I don't get confused.
