Question

POST-LAB (EXP #9) 1. The Ionization Energy of hydrogen is the energy required for the process: H + energy The literature for the ionization energy of hydrogen is 1.312 kJmo The ionization energy can also be thought of as the energy required to "promote" an electron from n-I ton"infinity" Prove through calculation the ionization energy of hydrogen is 1,312 kJ/mol. (Hint: the energy calculated using the Bohr equation is the energy of one atom and the ionization energy above is given per mole). 2. Of the all the electron relaxations for hydrogen (on page 9), pick the transitions which a. has the smallest energy: to b. has the largest frequency: n- n- to c. is the red line: to 3. A prism is able to differentiate the colors of the rainbow via refraction (bending of the light at various angles). The spectrometer uses a surface called a diffraction grating, which reflects light of various wavelengths at different angles. Give a real life example of an object or substance which acts as a di n grating, explain your reasoning.
