What is the wavelength (in nm) of the line in the spectrum of the hydrogen atom that arises from the transition of the electron from the orbital with n =3 to the orbital with n = 2?HINT: Look up Rydberg equation - in Lecture Notes B.
Note, the line corresponds to the energy of the photon that is emitted in the transition.
Consider the voltaic cell , which is based on the following cell reaction. Zn(s) + Cu2+(aq) Zn2+(aq) +Cu(s) Under standard conditions
What is the order of the reaction if it takes 10 minutes, 20 minutes, 30 minutes to reach 75% conversion?
