lewis vs bronstead

is it possible for an atom to be both a lewis acid and a bronstead acid? or a lewis acid and bronstead base?
does it just depend on each reaction or are certain elements always one or the other?

partial pressure workbook practice problem

Help! how do I solve this problem in quiz three prep: Fall 2013 #10 Bromine chloride, bromine, and chlorine gases have reached equilibrium in a container at 500K according to the reaction, 2BrCl(g) <--> Br2(g) + Cl2(g). Equilibrium partial pressures are 1.08 bar BrCl, 4.9 bar Br2, and 7.6 bar Cl2. H...

calculating concentration of K Notation

The book writes the K=products/reactants in a different format. is this something we need to know how to do? they are using P and Q and the chemical names as subscripts instead of just writing the chemical symbols in brackets. is this a completely different type of equation or is it just a different...

electron configuration of FC bond

After setting up the molecular orbital diagram, one may be asked to write the electron configuration of the molecular orbital. my question is do I only write down the configurations of the shells that have electrons occupying them? is there any need to write the config. of the 'LUMO' and putting it ...

Hybridization in general

How can you tell which molecules are hybridized? or are all atoms hybridized since all molecules have bonds?

How do I find out if there is an octet exception?

So is it simply an octet exception if I try to see up the lewis structure and the formal charges don't add up?

Sig figs when problem only gives you "n" values [ENDORSED]

So when a problem for example asks you to find the amount of energy it takes to move an electron from n=1 to n=3, and those are the only two numbers you are given in the problem, how many dig figs do I use? Should I use only 1? Or Should I use however many are given to me in planks constant or rydbe...

Hw problem 1.13

this question states: "use the Rydberg formula for atomic hydrogen to calculate the wavelength of radiation generated by the transition from n=4 to n=2."

I am not sure why the answer I am getting is a number to the power of negative 19 when the answer in the book is 486 nm.
thanks
