Calculating the Wavelength of a Photon Emitted in a Transition
I'm having trouble figuring this question out... I know that if I was dealing with hydrogen I would use the Rydberg constant and it would be smooth sailing, but I can't seem to find anyone online explaining how to solve this type of question when you are given energy differences between states and the atom is not hydrogen.
Any help is greatly appreciated.
[size=medium]The energy difference between n=2 and n=3 for an atom is 3.00x10-19 J and the ene

How are concentrations of acid and absorbance of a specific wavelength related?
I'm working on a lab where i used NaOH with concentrations of .2, .1, ,05, .025. and .0125 molarities. i measured their absorbance at 565nm and they all had 1 drop of phenophalien. I took readings every minute until 16 minutes passed. It looks like they all have a linear decrease in absorbance, but the .0125 concentration actually goes up. does this sound correct? how should each concentration of acid differ?

Finding the maximum wavelength that will eject an electron
Hey everybody i've been going over some of my practice exams and I am baffled by how I answer this one question. It provides the table

Wavelength of Light for a Transition in the Hydrogen Atom
The answer in the book is n = 1. I tried to do it myself and I got n = 5.92. I went on Yahoo Answers and this guy used Rydberg's formula: 1/w = R(1/L² - 1/U²) and he got the right answer. However, in my book Chemistry: A Molecular Approach by Nivaldo J Tro, the equation used in the sample problems and for these specific practice problems (there are 3, I did the first two and I got them right) is
ΔE = -2.18 x 10^(-18)J (1/n2(final)-1/n2(initial))

Calculating the wavelength of a photon using the energy change?
What is the energy change when the electron in a hydrogen atom undergoes a transition from the 4th energy level to the 2nd energy level? What is the wavelength of the photon emitted?
I've already worked out the first part of the question, which is E=4.09*10^-19J
Just wondering how to find the wavelength.
λphoton = hc / Ephoton
[size=medium]λphoton= (6.626*10^-34Js)(2.998*10^8ms^-1) / (4.09*10^-19J)[/siz
