Course Website General and section specific Chemistry 112 information can be found on PAWS (paws.usask.ca) under the COURSE TOOLS tab. This site will contain laboratory information, important updates, answers to most common questions about the course, and any section specific information. Updates and announcements will be posted on PAWS.

Final Grade The final grade is reported on a percentage scale. Your overall mark will be calculated based on the following weightings: Laboratory 20%, Assignments 10%, Midterm 20%, Final examination 50%. 01/15/2020 8:46 AM

Your final grade in the course will be assigned based on your overall mark. In order to be assigned a passing final grade, you must fulfill the following conditions: 1. Obtain an overall mark greater than 50%, AND 2. Attend the laboratory regularly and complete all required lab work (with no more than two approved absences) and obtain a 50% mark therein 3. Achieve a satisfactory performance in the examinations.

Examinations Midterm Examination: The mid-term examination will be held for all sections on Friday February 28, 2020 from 7:00 pm – 9:00 pm. Please mark this date and time on your calendar and plan now to ensure that your work and travel plans do not interfere with this schedule. For on-campus sections, an alternative midterm exam sitting is available upon application, for students unable to make the Friday midterm due to a valid conflict (job, childcare, etc.). This alternate exam is scheduled for 6:00 PM on Tuesday, March 3, 2020. Final Examination: The final exam will be scheduled by the Registrar’s office and will be held during the April final examination period. Exams can be scheduled at any time in the April 9 - 30, 2020. Do not schedule travel until after the official exam schedule is released (usually by early March). The Midterm and the Final Examination will be common to all sections of Chemistry 112.3. All examinations are cumulative and ‘closed-book’. Data sheets and other help will be supplied at the examinations, if required.

Homework Assignments The course textbook is fully supported by the Smartwork5 website. We will use Smartwork5 to assign graded and non-graded homework (see Final Grade above). The homework assignments will not only help you to test if you understand the material, but it will also teach you how to solve chemical problems. Some of the homework assignments are fully tutored, which is one of the strengths of the Smartwork5 website. Assignments should be done by all students individually. We note that students attempting to cut corners – including cheating - on assignments have always suffered in examinations. BEFORE you can register for SmartWork5, you need the right “Registration Code” (provided with a new textbook or can be purchased separately) and the correct “Student Set ID” for your section of the course. “Student Set IDs” are specific to each section. The link: http://bit.ly/nortonregistration shows a complete video on how to register and join a Student Set. Also, please see the Smartwork5 FAQ document in the course website for frequently asked questions (and answers) about Smartwork5TM. More important details may be given during the first week of lectures. Register AFTER these details have been presented during lecture. With your “Student Set ID” (see table below), your “Student Number” (see your student card), and your “Registration Code” you can then register on the website: https://digital.wwnorton.com/chem5 If you have used Smartwork5TM before (i.e. in another course) your login and password should still be valid, but you will need to register for the correct section of CHEM 112 using the appropriate 6-digit “Student Set ID”. 2

Academic honesty and integrity Honesty and integrity are expected of every student in class participation, examinations, assignments and other academic work. Every student must perform his or her own work unless specifically instructed otherwise. Cheating (includes plagiarism, copying or presenting other's work as your own ideas) on class assignments, quizzes, and exams will not be tolerated. Please read the materials posted at the University of Saskatchewan website: http://www.usask.ca/university_secretary/honesty/ The assessment of your course work, including a midterm or final examination, can be appealed using procedures posted at the University of Saskatchewan website: http://www.usask.ca/university_secretary/honesty/Student_Academic_Appeals.php

Consulting and Tutors You are encouraged to approach instructors and laboratory staff on an individual basis to discuss any aspect of the course. The Chemistry Learning Centre (Thorvaldson 162; located opposite the Chemistry main office.) will be available to Chemistry 112 students; times will be posted on PAWS and outside the Centre. Other tutor opportunities may be arranged by the Chemistry Student’s Society. The University of Saskatchewan Students’ Union (http://www.ussu.ca) and Chemistry Students Society (http://thecs2.ca/) both maintain a tutor database. 3

Please note that most Chemistry 112 instructors will generally respond to emails within 24 hours, during working hours. Please first check the course outline (this document) and the Chemistry 112 course website to ensure that the answer is not already posted.

PAL Peer Mentors The University Library harnesses the power of peer learning by training academically strong upper-year students to provide academic support. The philosophy of Peer Assisted Learning (PAL) is to provide positive, safe and comfortable learning environments that encourage, support and empower students in their academic pursuits. In Chem 112 Peer Mentors will be leading weekly structured study group sessions on the U of S campus. Details will be provided in class.

Other Information Calculator Policy: You should have a simple scientific calculator and know how to use it. Students may use a basic scientific calculator (e.g. Texas Instruments TI-30X series, Hewlett-Packard HP 10s or 30S) for all Chemistry 112 exams. Graphing or programmable calculators, or calculators with communication capability, are not allowed. For example, HP 35s, Casio fx-50FH, TI-83Plus calculators are not allowed. Ask your instructor if you are unsure whether your calculator is acceptable. Bring this calculator to all examinations, laboratories and tutorial sessions. Note that personal digital assistants (i.e. Pocket PCs, iPads, etc), wireless devices (cell phones, smart phones, iPhones, etc), and music players (MP3 players, iPods, etc.) will not be allowed during examinations. Please note that you will only be permitted to use a non-programmable calculator above during examinations. There will be no exceptions. Email: All University of Saskatchewan students are supplied with a university email account and are strongly encouraged to use the university account instead of Hotmail or Gmail (or other free email service) for any university-related correspondence. See http://www.usask.ca/its/guides/student_guide/ for more information about the services available to you and how to get your email account set up. Classroom Conduct: Learning chemistry will require your full attention. Therefore, we must ensure that our lecture halls and laboratories maintain an atmosphere that is conducive to learning. Disruptive activity (e.g. viewing videos, surfing the ‘net') is not permitted during lectures or laboratory periods. Ensure that your cell phone ringer is turned off before you enter the lecture hall or laboratory.

Course Description and Learning Objectives The course focuses on structure, bonding, and properties of materials with emphasis on both qualitative and quantitative aspects of chemistry. You will learn practical applications of chemistry through course material and laboratory experiments. The course strikes the careful balances between principles and applications and between qualitative and quantitative discussions. As a consequence, you will sharpen your skills in critical thinking and problem solving. Above all, the course will help you to understand the relevance of chemical concepts to your everyday life, and to your future career. Topics discussed in the lectures are listed below, with cross-references to the textbook and the learning objectives for each section. You should read and review the textbook together with the lectures to achieve your own comprehensive understanding of the course material. The textbook sections identified below are assumed reading throughout the course. The laboratory work is designed to both complement and supplement concepts presented with lectures and to develop skills in laboratory technique, observation, and data analysis. 4
