Calendar description: Thermochemistry, solutions and their properties, equilibrium, ionic equilibrium, pH, buffers, kinetics, reaction mechanisms, other selected topics related to biochemistry, biology, and engineering. Lectures and laboratory. NOTE: Students in programs leading to the BSc degree may not take this course for credit to be applied to their program of concentration.

Prerequisites: CHEM 205

Required background knowledge/skills: proficiency in high-school mathematics necessary (calculus not essential)

Expanded course description: General Chemistry II uses the chemical “language” learned in Chem 205 – atomic theory,

properties of elements, molecular structures, chemical reactions and stoichiometry – and applies it to build an understanding of what drives chemical processes. In this course, theoretical understanding, critical thinking and mathematical approaches are combined to solve chemical problems; the course leans heavily on mathematical calculations. Chem 206 is a course about learning to think like a scientist, by digging through everything you know in order to determine what knowledge is relevant and how best to approach the problem at hand. To succeed in Chem 206, you should REGULARLY work through problems from the textbook, especially the end-of-chapter General Questions these test your understanding and build your problem-solving skills by mixing concepts together, as they are encountered in the real world and on exams. Past exams are available on the course website, and you are encouraged to practice with them. The laboratory experiments further demonstrate how textbook chemistry is used to solve chemical problems. Together, the theory and lab work will give you a well-rounded introduction to some of the quantitative aspects of chemistry.

3. OBJECTIVES

Students are expected to:

o Draw on background: routinely use previously studied chemistry knowledge (Chem 205) and mathematics (algebra) o Acquire knowledge: memorize factual information, assimilate scientific concepts, learn calculations to apply concepts o Build competencies: attention to detail, explanation of cause & effect, application of knowledge to real situations o Develop skills: discipline, logic, qualitative & quantitative problem-solving, data analysis, laboratory techniques o Lay groundwork: for science courses: critical thinking, understanding chemical driving forces & relevance to science

7. RIGHTS AND RESPONSIBILITIES OF THE STUDENT

Read the Core Materials Moodle site within the first week of classes:

Full explanations of the course policies, activities, and helpful tips are provided there as FAQs (frequently asked questions). Please read it before the 2nd week of class – by registering for the course, you are agreeing to follow these rules. The information will remain accessible all term for your reference. If you have questions, please ask the Course Coordinator.

Be prepared for lectures, tutorials & labs:

Lectures: Read the lecture materials before class, and then be ready to (i) answer clicker questions (including calculations) during the lecture and (ii) engage in discussion with classmates to clarify each others’ understanding.

Tutorials: Study the pre-assigned topics posted on the Moodle Core Materials lab/tutorial schedule & complete the hand-in problems, and then be ready to (i) work in small groups at the tutorial and (ii) write a quiz (individually).

Labs: Read the experiment thoroughly & complete the prelaboratory exercises (individually), and then be ready to (i) perform the experiment together with a lab partner and (ii) write a lab report based on your data (individually).

Contribute to a positive learning environment:

Disruptive or disrespectful behaviour will not be tolerated in classrooms or laboratories. Cell phones and other electronic communication devices may not be used in these settings. Laptop computers are permitted for course-related activities. Students engaging in inappropriate behaviour will be asked to leave, without the opportunity to make up the missed work.

Complete the Chem 101 seminar & quiz:

MANDATORY COURSE REQUIREMENT: As part of this course, you are required to (i) attend a Chemistry & Biochemistry Departmental “Chem 101” seminar on the Academic Code of Conduct and the appropriate use of information sources, and then (ii) pass the online Chem 101 quiz (passing grade 100%). The aim of Chem 101 is to clarify the Academic Code of Conduct in terms of what practices are considered unacceptable with regards to work submitted for grading in Chemistry & Biochemistry courses. If you have already completed Chem 101, you are not required to repeat it.

The short seminar will be held at the times shown in the table. Space at each seminar is limited by the room size; please sign up for your preferred time. Sign-up sheets will be available in the Chemistry & Biochemistry Departmental office, SP 201.01.

If you do not complete Chem 101, your final Chem 206 grade will be lowered by one letter grade and carry an incomplete notation (e.g., C+/INC if you earned a B-). Please refer to the Undergraduate Calendar (section 16.3.6) for details on removing an incomplete notation (thus restoring your grade) via the “Late Completion” process.

Demonstrate academic integrity: Source: Academic integrity website: http://provost.concordia.ca/academicintegrity/plagiarism/

Plagiarism: The most common offense under the Academic Code of Conduct is plagiarism, which the Code defines as “the presentation of the work of another person as one’s own or without proper acknowledgement”.

This could be material copied word for word from books, journals, internet sites, professor’s course notes, etc. It could be material that is paraphrased but closely resembles the original source. It could be the work of a fellow student, for example, an answer on a quiz, data for a lab report, or a paper or assignment completed by another student. It might be a paper purchased through one of the many available sources. Plagiarism does not refer to words alone – it can also refer to copying images, graphs, tables, and ideas. “Presentation” is not limited to written work. It also includes oral presentations, computer assignments and artistic works. Finally, if you translate the work of another person into French or English and do not cite the source, this is also plagiarism. In simple words: DO NOT COPY, PARAPHRASE OR TRANSLATE ANTHING FROM ANYWHERE WITHOUT SAYING FROM WHERE YOU OBTAINED IT!

Chem 206 – LECTURE SCHEDULE – Winter 2010

Suggestions on how to approach lectures:

o Read the assigned textbook sections before each class. Lectures are intended to clarify your understanding of the topics covered in the textbook and to get you actively thinking about the material. Lectures do not replace the readings.

o Print out the lecture slides and bring them to class to write on. Slides will be posted on Moodle 2-3 days before class. o Take notes during class to recall the explanations & discussion. Don’t waste time copying down what is on the slides! o Think actively in the classroom: participation via answering in-class clicker questions & engaging in peer-instruction

activities with classmates will comprise part (5%) of the course grade. NOTE: section 52 = single date shown per week; section 01 = two dates shown per week (01 MT exam Feb. 17th). NOTE: section 01 lecture dates affected by University closures for Easter (Apr.2-5); note the week 12-13 dates (*) below.
