Chemistry 121: Atomic and Molecular Chemistry Course Outline Winter 2010

Page 1 of 3

Instructor: Rob O’Brien (Sci 163) 807-9569 email: Rob.OBrien@ubc.ca Course Description: Stoichiometry, atomic and molecular structure, chemical periodicity, gases, liquids, solids, and solutions. Required course for all students needing a first-year Chemistry course who have Chemistry 12. [3-3-0] Learning Objectives: Students in Chemistry 121 consider an introduction to modern theories of atomic structure and molecular bonding, and use these models to explain the nature and behavior of matter in the gaseous, liquid, and solid phases. The course also briefly reviews fundamental principles of chemical stoichiometry from Chemistry 11 and 12. A student who completes both Chemistry 121 and 123 will have the ability to quantitatively and qualitatively interpret physical and chemical changes in terms of molecular properties, and will be well prepared for further studies in science generally and chemistry specifically. Lectures: The lectures are designed to define the course curriculum and to present core material in an interactive medium. You are expected to prepare for lectures by reading materials in your text book and other supplementary sources. Lectures will be presented : 8:00am - 9:20am; Monday, Wednesday. Fip 204 8:30am - 9:20am; Friday. Fip 204 Supplementary Materials: I will provide a range of supplementary material on my web site or links to other such material on this site. This material is provided to augment your learning experience. I am experimenting with various multimedia formats and therefore any of this material should be considered bonus material rather than an integral part of the course. Laboratory: Laboratory instruction is an integral and important part of the course. You are responsible for ensuring you are enrolled in an appropriate laboratory section. Failure to achieve independent passing grades (50%) in both the lecture and the lab results in a maximum possible course grade of 48%. Required Text / Material: 1. General Chemistry: Principles and Modern Applications, 10 Edition, Petrucci, Herring, Madura, & Bissonnette; Prentice Hall (2011) ISBN-10: 0136121497 2.

Quizzes: Weekly quizzes will be administered through WebCT/Vista, an online course management tool, available at http://www.vista.ubc.ca. Students will have a time window during which they may log in and complete the quiz. Results and answers will be posted after each quiz is complete. Term and Final Exams: There will be two term tests of 50 minute length (October 8 and November 10), and a cumulative final exam during the final examination period, December 8 – 22 (including Saturdays). It is the student’s responsibility to be available for all examinations. Calculators with programmable memories are neither required nor permitted for exams – a calculator with scientific notation, exponents, and logarithms will be sufficient. It is your responsibility to review and understand the UBC policies on academic misconduct. The section describing the nature and consequences of academic misconduct are described in Chapter V of the UBC calendar: http://okanagan.students.ubc.ca/calendar/index.cfm?tree=3,54,111,0 If you require disability related accommodations to meet the course objectives please contact the Coordinator of Disability Resources located in the Student development and Advising area of the student services building.
