BEFORE STARTING THE EXAM PUT YOUR FORM # IN COLUMN P AND YOUR SECTION # IN COLUMN K AND L ON THE SCANTRON. ALSO DARKEN THE CIRCLES PLEASE. 1. The number of cubic nanometers in 1 cm 3 is A. 10 27 B. 10 36 C. 10 21 D. 10 8 E. 10 -27 2. Consider some oxides of the fictional nonmetallic element rutgersium (Rg) in column IVA of the periodic table. It forms three oxides, rutgersium monoxide, rutgersium dioxide, and rutgersium suboxide (Rg 2 O 3 ). In the monoxide we find that 1.00 g of Rg is combined with 1.50 g of O. Which one of the following sets of mass compositions is correct? A. choose this choice if none of the others is correct B. dioxide 1.00 g Rg, 4.00 g O; suboxide 2.00 g Rg, 3.00 g O C. dioxide 2.00 g Rg, 6.00 g O; suboxide 1.50 g Rg, 4.50 g O D. dioxide 1.00 g Rg 3.00 g O; suboxide 1.00 g Rg, 2.25 g O E. dioxide 2.00 g Rg, 1.50 g O; suboxide 1.00 g Rg, 2.25 g O 3. A compound contains 70.9 % Xe, 20.5 % F, and 8.6 % O, by mass. The empirical formula of the compound is A. XeOF 2 B. Xe 2 O 2 F 2 C. XeO 2 F D. Choose this choice if none of the others is correct E. Xe 2 OF 4. A 10.00 g sample of a compound with the formula XCl 2 reacts with excess Cl 2 to form 13.55 g XCl 4 according to the reaction XCl 2 + Cl 2 XCl 4 The atomic weight of X is A. 207 B. 71.0 C. 104 D. 129 E. 258 5. The mass of 0.532 mol of the compound XSO 3 is 55.5 g. Using the periodic table and these data, X can be identified as A. Al 161EXAM II V1 FALL 2003 2
