Course Material
Required Textbook (McGill Bookstore, $99.90 $179.95) (SAME AS CHEM 110)
Chemistry: The Molecular Nature of Matter and Change (2nd Canadian Edition) by Silberberg, Amateis,
Lavieri, and Venkateswaran
Hard cover text + Connect/e-book + Digital Student Solutions Manual $179.95
Connect/e-book + Digital Student Solutions Manual $ 99.00
* copies of the text will also be available on reserve in the Schulich Library (Science/Engineering)
Connect Online Learning
Purchasing the textbook/ebook gives you access to the McGraw-Hill online learning system ‘Connect’.
This program will be used for weekly ‘LearnSMART’ readings and ‘Connect’ homework assignments. The
homework site can be accessed directly from our myCourses lecture page.
In-Class Polling ‘Turning Point Cloud’
Polling will be used in this course as a self-check for your understanding of course content, to provide us
with feedback, and to enhance your engagement in class. Polling will NOT be used for grading.
During a class with polling questions, you will be asked to respond to questions from the instructor from a
personal device (smartphone, tablet, or laptop). Please come to class with your devices charged and
connected to the Internet. If you do not have a phone, tablet, or laptop to use for polling questions, and wish
to participate, please contact the instructor immediately in order for appropriate arrangements to be made.
Polling will be available through using your McGill username/password.
Any non-programmable/non-graphing calculator is required (e.g. CASIO fx-991MS or Sharp EL510), as
graphing or text storage calculators will not be permitted in midterm or final examinations at McGill.
Lecture Notes/Recordings
Course notes will be available as pdf files on myCourses before lecture. We encourage you to print the
slides (4/6 per page), bring them with you to class, and add your own notes during lecture.
Lectures and lecture-style tutorials will be recorded and available through the ‘Lecture Recordings’ tab in
myCourses. We recommend that you attend class and only use the recordings as a review tool. If you have
to miss a class, make sure you view the missed lecture recording before rejoining the class.
Course Evaluation and Key Dates Standard Missed Midterm* Exempt from Lab
Midterm I 20% 30% (I or II) 25%
Midterm II 20% ----- 25%
Final Exam

Connect weekly 5% (0%) 5% (0%) 5% (0%)
Grade with vs. without Connect will both be calculated and students will be awarded the highest outcome.
Room assignments for midterms will be posted on myCourses ~24h before the exam.
Room assignments for the final exam are handled by the Exam Office (posted mid-March)
* If you are unable to write a midterm, you must contact us ( before the
exam only legitimate medical or academic excuses will be accepted. Students excused from writing a
midterm will have the points equally redistributed between the other midterm and final exam. In the unlikely
event that you miss both midterms, your final exam will be weighted 75%.
Please be clear that no instructor at McGill is authorized to alter the time/date of a final exam or to offer a
special writing opportunity; these issues can only be dealt with at the McGill Service Point. If you have
too many exams in a short period of time consult:
Policy Statement on Academic Integrity: McGill University values academic integrity. Therefore, all students must
understand the meaning and consequences of cheating, plagiarism and other academic offences under the Code of
Student Conduct and Disciplinary Procedures (see for more information)
(Approved by Senate on 29 January 2003)
Policy Statement on Language: In accord with McGill University’s Charter of Students’ Rights, students in this
course have the right to submit in English or in French any written work that is to be graded. (Approved by Senate
on 21 January 2009)
Conformément à la Charte des droits de l’étudiant de l’Université McGill, chaque étudiant a le droit de soumettre
en français ou en anglais tout travail écrit devant être noté (sauf dans le cas des cours dont l’un des objets est la
maîtrise d’une langue).
Policy Statement on Extraordinary circumstances: In the event of extraordinary circumstances, the content and/or
evaluation scheme in this course is subject to change.
Policy Statement on Course Material: Instructor-generated course materials (e.g., handouts, notes, summaries,
exam questions, etc.) are protected by law and may not be copied or distributed in any form or in any medium
without explicit permission of the instructor. Note that infringements of copyright can be subject to follow up
by the University under the Code of Student Conduct and Disciplinary Procedures.
Policy Statement on Diverse Learners: As instructors of this course we endeavor to provide an inclusive
learning environment. However, if you experience barriers to learning in this course, do not hesitate to discuss
them with us and the Office for Students with Disabilities, 514-398-6009.
Learning Objectives
Chemistry 120 aims to provide you with an introduction to the quantitative aspects of fundamental chemical
principles, such as gas law, thermodynamics, kinetics, solubility, equilibrium, acids/bases, and
electrochemistry. This course compliments the more qualitative principles/topics presented in Chem 110.
Here, our focus is on developing an understanding of these underlying principles that dictate chemical
behavior and reactivity.
Instructional Methods
There is no one way of learning chemistry. In this course, you will have access to a variety of resources
which we hope will provide you with an opportunity to engage with the subject. Looking over material
before class, through the LearnSmart Pre-Readings, will prime your brain to learn what is being presented
in lecture. Connect Assignments will be provided for you to engage with what you learn in class. Practice
exams will be provided so you can acclimatize yourself to the style of multiple choice exams. We strongly
recommend engaging with these resources whether it’s working on them independently or with your fellow

* for any questions related to the labs, see Mitch Huot (Pulp & Paper 118A)
Labs will begin on 14th January.
You must read the detailed lab syllabus and watch both a lab safety video and a lab introductory videos at
the start of the course. The lab syllabus and videos are accessible via our lab myCourses page. Once you
have read the syllabus and watched the videos you will need to complete a safety/syllabus/schedule quiz.
The quiz is not worth any marks but you will need to complete it and receive 9/9 in order to access the
rest of the course material. You have an unlimited amount of attempts for the quiz.
All lab information will be available through myCourses (including the lab schedule and lab manual).
Personal safety equipment is required for the initial lab, so ensure you have purchased lab coat and safety
glasses. Lab coats and safety glasses will be available for sale in the Holmes Room (basement of Otto
Maass) during the first few weeks of class. Come to the lab (Otto Maass 1 in the basement of Otto Maass)
according to your scheduled lab section (schedule available on myCourses)
The laboratory counts for 20% of the course grade, but is a required course component. If you fail the lab
and pass the lecture, you will receive an “F” grade and must redo the entire course.
Lab Exemption
If you are repeating this course, you could be eligible for a lab exemption. You must have passed the lab
component within the past 3 years. Contact Mitch Huot to confirm your eligibility for a lab exemption and
obtain authorization. Be aware that when exempted from the labs, only midterm and final exam grades
count to your course grade (see “Course Evaluation and Key Dates” above). Lab grades are not transferred
from previous years.
