Happy Mole Day Chemistry 1 Exam 2 BP October 23, 2009 Name ____________________ Student ID # __________ Section __________ It is critically important that you show clear and logical responses, use proper chemical equations, units, and show calculations quantitatively! 1. (16 pts) The Pfund series of emission lines for the hydrogen atom is from all higher states to the n = 5 ground state. The book only shows the first two transitions in its diagram for hydrogen. ( h = 6.626×10 -34 J·s, R = 1.097×10 7 m -1 , c = 2.998×10 8 m·s -1 ) a) Calculate the wavelength of the transition from the third excited state with respect to the n = 5 ground state. b) Calculate the frequency of the transition from the third excited state with respect to the n = 5 ground state. c) Calculate the energy of the emission from the third excited state with respect to the n = 5 ground state. d) How much energy must be absorbed to get from the n = 5 ground state to the third excited state ? e)
