Introductory Chemistry II (CHMA11H3)
Winter 2019
University of Toronto at Scarborough
Welcome to Introductory Chemistry II: Reactions and Mechanisms! Chemistry is an exciting subject with far-
reaching applications in countless disciplines (biology, medicine, geology, environmental science,
neuroscience, forensics, food science the list goes on!). CHMA10 might have given you a taste of this, but in
CHMA11 we’re going to take things even further. We’ll be continuing to teach you the fundamentals of the
subject, but our hope is that this course will also give you an appreciation for the depth and importance of this
discipline. By the end of the semester, you should be thoroughly convinced that chemistry is indeed all around
you! Before we get started, please read through this syllabus. It contains important information, which will
help make sure you have all the tools you need to succeed in this course.

Peer Facilitator Program: Facilitated Study Group (FSG) is being run through the Centre for Teaching
and Learning. These weekly sessions are open to all students taking this course who want to improve their
understanding of course material, improve their study techniques, and improve their grade. Attendance is
voluntary. In these sessions you will compare notes, discuss important concepts, develop study strategies,
and prepare for exams and assignments on course material. Course material is NOT re-lectured. The
FSG’s are led by a trained facilitator who has previously taken the course. A survey will be taken during
the first week of class to determine the best days and times for most students, and they will begin
probably the 2nd or 3rd week of class. CHMA11 is supported by FSGs. These weekly study sessions are
open to everyone in the class. Attendance is voluntary, but students who attend regularly often earn
higher grades. Please be sure to fill out the survey in the first week of class to help ensure the study
groups are scheduled at optimal times. If you have any questions, please ask your facilitator, or visit the
FSG website at

Midterm and Exam Policy:
Midterm: There will be 90 minutes mid-term test written outside of class either just before or just after
the Reading Week. The exact date, time and location will be announced as soon as they are available. If
you miss the midterm due to legitimate reasons, you must submit the official supporting document within
one week of your absence to be considered to write the make-up test. If the reason is medical, an official
UTSC medical form should be downloaded from the Registrar’s website: completed and
signed by your physician. If no acceptable documentation is received, you will receive a zero for that
Final Exam: There will be a 3-hour, cumulative exam written during the end of semester exam period.
The exact date, time and location will be announced as soon as they are available. Please note that if you
miss the Final Exam, you must petition the Registrar's Office to write a make-up exam in the next formal
exam period. Check the UTSC Calendar for instructions and deadlines.
Allowed Aid: Only non-programmable, non-communicating calculators are allowed in tests and
exams for this course (both lecture and lab). Students must bring their own calculators.
The laboratory component of CHMA11 is compulsory. In order to pass the course, you must also pass the
lab component.
Lab Schedule:
Laboratory periods are three hours in length and run every other week. Laboratory Section Schedule:
Week 1 lab students: Students assigned to practical sections ending in odd numbers will begin their labs
on the week of January 14th 2019
Week 2 lab students: Students assigned to practical sections ending in even numbers will begin their labs
on the week of January 21st 2019.
Lab Manual and Notebook:
A lab manual must be purchased from the UTSC Bookstore before your first lab. You may not use a lab
manual from a previous semester: the experiments and course requirements will be different.
DO NOT wait to purchase your lab manual as it contains a host of important information:
- Lab Schedules and other important dates
- Late and absence policies
- Rules regarding safety
- Appropriate attire for the labs
- Marking schemes
- Guidelines on how to properly prepare for the lab
The bookstore DOES NOT stock enough lab manuals for everyone. If they run out, you MUST pre-
order a copy through the bookstore this takes time. Failure to adhere to the rules and policies outlined
within the lab manual will adversely affect your lab mark in some instances the impact will be severe.
In addition, students will be required to purchase their own lab notebook. The book must be hard-cover,
permanently bound (not spiral or loose leaf) with the approximate dimensions 8.25” x 10.5” inches. They

can be purchased at the UTSC bookstore; however students are free to purchase their books at a merchant
of their choice (so long as they meet the above requirements). Students are allowed to reuse their lab
notebook from previous courses (just make sure that your table contents reflects the fact that the book
contains material from multiple courses).
Lab Safety:
Safety in the laboratory is an extremely important element in the chemistry program at this University.
Failure to follow safe practices can cause laboratory accidents which may result in the loss of time,
damage to clothing, and other property, and most importantly personal injury. By following suitable
precautions, you can anticipate and prevent situations that would otherwise lead to accidents. Students
registered in CHMA11H3S will be automatically enrolled into the course which should appear in your
“My Courses” window of your blackboard home page.
As part of this course, students will be expected to watch a video (approximately 30 minutes long) and
take a multiple choice quiz on the material you just learned (the quiz is different than the previous
term). Students must obtain 80% on the quiz to pass the WHMIS course. In addition, students will be
required to print off their quiz results and present them to your TA before you will be allowed to
enter the lab.
Safety Equipment:
Students will be required to purchase approved indirect vented chemical splash safety goggles, and a lab
coat before attending their first lab. These items can be purchased through the bookstore. All safety
eyewear must meet either ANSI Z87+ or CSA Z94.3 Standard for high impact protection (if you see one
of those standards stamped on your eyewear somewhere then they meet that particular standard).
Labs coats must be 100% cotton no exceptions.
Further information regarding appropriate attire please see the guidelines outlined in your lab manual.
Note that students not wearing approved safety gear will not be allowed to participate in the lab.
Ancillary Fees
Students taking CHMA11 will be assessed a $25.00 ancillary fee which will cover the cost of chemicals,
filter paper, Pasteur pipettes and other items consumed over the course of the lab. For more information
regarding ancillary fees students are encouraged to visit the following website:
Absence: If you miss a significant period of class work through illness or a related reason, you should
request consideration by submitting a completed University of Toronto Student Medical Certificate which
is available on the following web site:
The document must be presented within one week of the date of absence. However, you should notify the
course instructors the day of your absence (see your lab manual regarding absences from the lab). Only
serious illness (or equivalent reasons) will be accepted as justification for absence (note: the U of T
Medical Certificate, filled out by your doctor, stating that you saw him/her on a given day is not adequate.
Your doctor must certify that you were too sick to attend the test, etc.). The form of consideration
extended for a particular item of missed term work will be explained to you when you submit the

According to Section B of the University of Toronto's Code of Behavior on Academic Matters which all students are expected to know
and respect, it is an offence for students to:
To use someone else's ideas or words in their own work without acknowledging that those
ideas/words are not their own with a citation and quotation marks, i.e. to commit plagiarism.
To include false, misleading or concocted citations in their work.
To obtain unauthorized assistance on any assignment.
To provide unauthorized assistance to another student. This includes showing another student
completed work.
To submit their own work for credit in more than one course without the permission of the
instructor. To falsify or alter any documentation required by the University. This includes, but is
not limited to, doctor's notes.
To use or possess an unauthorized aid in any test or exam.
There are other offences covered under the Code, but these are by far the most common. Please respect
these rules and the values which they protect. Offences against academic integrity will be dealt with
according to the procedures outlined in the Code of behaviour on Academic Matters.
