Name: ____________________ Student number: ______________ Chemistry 1AA3 Final Exam April 20, 2007 McMaster University VERSION 1 Instructors: H. Jenkins, B. McCarry, H. Stöver Duration: 3 hours This test contains 30 numbered pages printed on both sides. There are 34 multiple-choice questions appearing on pages numbered 3 to 15. Page 26 includes some useful data. There is a periodic table on page 30. Pages 27 - 29 may be used for rough work. You may tear off the last pages to view the periodic table and to do your rough work. You must enter your name and student number on the question sheets, as well as on the answer sheet . Your invigilator will be checking your student card for identification. You are responsible for ensuring that your copy of the question paper is complete. Bring any discrepancy to the attention of your invigilator. Questions 1 to 24 are each worth 2 marks; questions 25 – 34 are each worth 3 marks. The total marks available are 78. There is no additional penalty for incorrect answers. BE SURE TO ENTER THE CORRECT VERSION NUMBER OF YOUR TEST (shown near the top of page 1), IN THE SPACE PROVIDED ON THE ANSWER SHEET. ANSWER ALL QUESTIONS ON THE ANSWER SHEET, IN PENCIL. Instructions for entering multiple-choice answers are given on page 2. SELECT ONE AND ONLY ONE ANSWER FOR EACH QUESTION from the answers (A) through (E). No work written on the question sheets will be marked . The question sheets may be collected and reviewed in cases of suspected academic dishonesty. Academic dishonesty may include, among other actions, communication of any kind (verbal, visual, etc .) between students, sharing of materials between students, copying or looking at other students’ work. If you have a problem, please ask the invigilator to deal with it for you. Do not make contact with other students directly. Try to keep your eyes on your own paper – looking around the room may be interpreted as an attempt to copy. Only Casio FX 991 electronic calculators may be used; but they must NOT be transferred between students. Use of periodic tables or any aids, other than those provided, is not allowed.
