Re: quantum numbers

Someone once taught me to think of quantum numbers as the following: n= the floor of the building ( 1, 2, 3, ...floor on the periodic table) l = the apartment # on that floor (0=s, 1=p, 3=d 4=f) ml= the room number inside the apartment (what room does the electron stay in, or what line out of the or...

Re: mmol and mol

You can probably do it in the way that is most comfortable for you, just as long as your answer is in the desired units the question asks for (that is if it even asks).

Re: Naming Complexes

Does using bis or tris apply to (dien) (edta) or (oxo) the way it does to (en)?

Re: Atomic absorption of energy

It is important too to note when an electron moves from higher to lower energy level your delta E will be negative. For example Q2 on the 2011 Final.

Henderson Hasslebach Equation

I understand the equation ph=pKa + log (conjugate base concentration / concentration of acid)
How do you apply this to a Strong acid weak base titration? Is the equation different, how so? I've seen multiple versions and not sure what is right.

Re: Strength of acids

So how do you apply this to a question on the 2010 final, question 5 ranking HClO4 HClO3 HClO2 and HClO based on their Lewis structures?

Re: Valence Shell Energy Levels and Orbitals

So for any atom that is in the 3rd period in the psubshell it has an n value of 3. If you recall from the quantum numbers lecture for any value of n, l can equal n-1, n-2...0. Therefore for atoms like P, S and Cl with an n value of 3, l (which represents the orbital quantum number) can be 0, 1, or 2...

Re: Uncertainty of Momentum and Position [ENDORSED]

If I understood your question correctly, there will always be uncertainty in the electron's position and momentum due to the difficulties of obtaining exact measurements of electron movement/location.
