For SO4, I understand that it's a nonmetal, and therefore going to be acidic, but when I draw the lewis structure, there doesn't seem to be any need for it to accept any more electrons. So why is it still acidic?

Can someone explain why in part B of this problem, BF3 is a lewis acid?

In 12.3d, the acid HCOOH donates its proton to become the conjugate base HCO2^-

I understand this problem, but I was wondering, is it wrong to write HCOO^- as opposed to what the solutions manual says (HCO2^-)?

Is there a difference?

I was wondering about this too, but I read another post addressing this issue and the way I understand it now is that the sum of the charges of atoms inside the brackets will be opposite of the charge of the atom on the outside of the brackets. (Someone correct me if I'm wrong, or phrasing it wrong)...

17.29 asks us to name the complex (which I understand) and then to determine the oxidation number of the metal. The solutions manual gives a formula for finding the oxidation number of the metal: (# of metal atoms)(oxidation number of the metal) + ∑(# of each ligand)(charge of each ligand) = charge ...

Yes, they are the same ligand. "Cyano" is the older version of the name whereas "cyanido" is the newer version.

The atom is TeCl4. The question asks to write the Lewis structure, VSEPR formula, shape, and predicted bond angles. I understand everything including the fact that it is See-Saw shaped. However, the solutions manual lists the bond angles as 90 degrees and 120 degrees. First, why are there two bond a...

I was wondering about the same question (4.13a). The solutions manual lists two lone pairs on the right side of the central Iodine atom and one lone pair on the left side. This drawing makes it look like it should be angular. Can someone explain why it's linear?

4.7 (a) "What is the shape of the thionyl chloride molecule, SOCl2? Sulfur is the central atom." This problem explicitly gives sulfur as the central atom; however, in this instance, is it acceptable to use Oxygen as the central atom should the problem not have specifically given the centra...

3.11 Question: Which M^3+ ions (where M is a metal) are predicted to have the following ground-state electron configurations: (a) [Ar] 3d^6 (b) [Ar] 3d^5 The solutions manual says: (a) Co^3+ (b) Fe^3+ To find this, do you simply add 3 electrons to the given ionized configuration (i.e.: [Ar] 3d^6), f...
