Q5 2010 Exam--Determining level of acidity of Bronsted Acids

The question says:
Determine the most stable Lewis structure for the following Bronsted acids and list them from least acidic to most acidic: HClO3; HClO; HClO2; HCLO4. Explain their trend in increasing acidity.

Can someone please explain why HClO4 is more acidic then say, HClO?

Clarification on J.1B

I noted that another person asked about KOH being a Bronsted base or not, and in the book it says that it "supplies the base OH-". However, I think that it says that it "supplies the base" because it specifically asks to identify if KOH is a Bronsted acid or base in water. When i...

Re: Ending for Coordination Compounds

When naming compounds within the coordination sphere, you'd name something with -ate, such as chromate, when the charge of the complex is negative (so the charge outside of the brackets is negative). Notice that the suffix -ate applies to the transitional metal and that it is an anion. The ending -i...

HW 17.37 Spin-off

In each example, there wasn't an anion or cation outside of the brackets. When counting the number of ligands, will the anion and/or cation outside of the brackets be included in the counting for coordination number?

Re: Naming and Order

I thought that aqua could be written as either H2O or OH2. On page 741 of the textbook, it explains why the order of the atoms is changed and all it says is, "If a particular point needs to be emphasized, then the order may be varied". On page 106 in the course reader, it has an example wi...

Re: Naming and Order

I'm not too sure how to answer your first question but here goes a shot for your second question.
Water as a ligand is denoted as Oxygen and then two Hydrogens to emphasize that the O links to the metal atom. So, from what I've seen so far, water is sometimes written like that.

Re: acids and bases

A Lewis acid acts as the "acceptor" while the Lewis base acts as the "donator" when forming a coordinate covalent bond. The thing that is being "accepted" or "donated" is electrons because even though this type of reaction has a specific name, we are still dea...

Vectors in Relation to Polarity

Can someone please clarify how to tell if a molecule is polar or not in relation to vectors? I understand that in order for a molecule to be polar, there must be dipoles that do not cancel and as far as I understand, dipoles are vectors. I read in one of the questions about polarity before that symm...

Re: Valence Shells

Theoretically speaking, Lithium can gain electrons instead of losing them. What happens, however, is that the other element that it is bonded to, say Oxygen, becomes less electronegative. Essentially, you are making an element that is close to achieving noble gas configuration positive and that is w...

Re: Rydberg Formula

Are you speaking of a specific homework problem, maybe? If so, the context if the problem will let you know what n is equal to. For example, in HW problem # 1.13, you are explicitly told that n=4 and n=2, meaning that the numbers you plug into the Rydberg equation will be 2 and 4. So, in short, the ...

Re: Precision on the frequencies

Adding onto that, the energy of it can be exactly the same as the energy required to excite the electron and just result with zero excess energy.

Clarification on description of a photon

I understand that light can behave like a wave and a particle. The particle is referred to as a photon and is described as, "discrete packets of energy". What does it mean for it to be "discrete" in the context of the photoelectric effect?

Re: Relationship between frequency and wavelength

Also, if you look at the equation where the wavelength of light (represented with lambda) times the frequency (represented with the letter v) is equivalent to c, we know that if we are given the wavelength and asked to find the frequency, we can find the answer because they are inverses and that all...
