Unformatted text preview: Name: Chemistry 007, Fall 2007 Cornell University Dr. Pontrello Final Exam Review Questions To prepare for the final exam, I suggest that you print blank copies of the Chem 207 Assignments and Exams and the Chem 007 Questions and provide answers. Also review your class notes and sections in the textbook that you find difficult. Finally, attend office hours and review sessions as needed. The following additional questions will be addressed as needed during the Final Exam Review on Saturday December 8 th from 2-4pm in Baker 200. Part I: Formulas, Electron Transitions, and Orbitals. I.1 (9 points) The drug Nasonex has a molecular mass of 521.43 g/mol. Nasonex contains the elements C, O, H, and Cl. Elemental analysis indicates mass percent values of 5.80% H, and 18.41% O. Combustion of a 56.7 mg sample of Nasonex gives 129.2 mg of CO 2 as the only product containing carbon. What are the empirical and molecular formulas of Nasonex? Name: 2 I.2 (6 points) What is the wavelength of light absorbed by an electron promoted from the n=2 to n=4 level in a Li 2+ ion? I.3 (14 points) What are the possible quantum numbers of a 4p orbital? Roughly plot the radial probability distribution of the 4p x orbital with the radius along the x axis. Indicate nodes in the plot. How many radial and angular nodes are present in the 4p x orbital? Draw a contour map of the 4p x orbital along the x and y axes. Label the radial and angular nodes in the map. Name: 2 I.2 (6 points) What is the wavelength of light absorbed by an electron promoted from the n=2 to n=4 level in a Li 2+ ion?
