CHEMISTRY 12
Sands Secondary School
Ms. Hamilton
Texts:
Hebden Chemistry 12 student workbook
You will need:
Writing materials, lined paper, graphing paper, and a non-programmable scientific
calculator.
Course content:
Introduction:
Review of chemical naming, formula writing, the balanced chemical equation,
and the mole.
Reaction Kinetics:
Introduction to “rate”. Recognize that reactions proceed at different rates
depending on nature of reactants, the products and conditions of the environment.
Learn methods to measure and monitor rates. Understand collision theory,
reaction mechanisms, activation energy, activated complexes and catalysts.
Energy and chemical reactions: Understand that molecules have kinetic and potential energy, that energy
changes during reactions, that enthalpy and entropy changes affect the direction of
a chemical reaction and that many reactions are reversible. Learn the conventions
of ∆H and ∆S.
Equilibrium:
Understand why some reactions are reversible and some are not. Learn about
forward and reverse reactions and conditions of equilibrium. Understand how
stresses can change the equilibrium. Calculate “k”, the equilibrium constant and
apply Le Chatelier’s Principle. Recognize when “k” favours the reactants or the
products.
Equilibrium in solutions:
Recognize the equilibrium established between a solid and its saturated solution.
Understand the table of general solubilities, calculate the solubility product of a
given substance and use the common-ion effect to predict precipitation and/or
maximum permitted concentration.
Acids, bases and salts:
Learn about acids, bases and salts, their properties and their uses, the importance
of water, the Bronsted-Lowry and Arrhenius definitions, weak and strong acids,
competition among bases for the proton, ka, kb and kw, the formation and
hydrolysis of salts, acid/base indicators and titration, and acid rain, its
consequences and possible remedies.
Oxidation and reduction:
Understand the historical definitions based on competition for the electron, learn
about strong and weak oxidizing and reducing agents and use the table of
reduction potentials. Understand the importance of the electrochemical cell and
electrolytic cell and their applications.
Assessment:
Students will be assessed using both formative and summative indices. In class
work includes note taking, discussion, lab work, in-class assignments, and
quizzes. Homework is assigned daily and will include reading, writing,
completing worksheets or textbook questions and writing lab reports. There are
also periodic unit tests, a mid-year exam and a final exam.
Grading:
Marks breakdown:
A cumulative mark is maintained throughout the year. Student/parent connect is
kept updated regularly. Formal reports are given to parents throughout the year.
The cumulative mark is based on:
Homework + lab reports + quizzes
Unit tests
Mid-year exam
20%
70%
10%
At the end of the year students will write a final exam. At that time the
cumulative mark and exam mark are combined to give the overall final mark:
Cumulative mark
Final Exam
80%
20%
How to do well:
Read your notes at home after every class. Do your homework on the day that it
is assigned (all homework is due next class) and be sure to hand it in when it is
due. If you know ahead of time about a planned absence, talk to me so we can
arrange for you to keep up. If you have an unforeseen absence, get the notes and
homework from a friend and see me as soon as possible to get caught up. Don’t
be afraid to ask for help. I’m at school most days by 7:30 am and am often in my
room (201) at lunch time and for a short time after school every day. I encourage
you to come and ask for clarification whenever you need it! Also, I keep a page
on the Sands website that you can check for homework and test dates.
Other helpful resources:
“The Key” has sample provincial questions and solutions from past years. It is
helpful to work through each unit as we cover the material in class. Some old
provincial exams and answer keys are still available on line at the ministry of
education website. I will be providing you with sample questions during a review
period at the end of each unit to help you prepare for tests.
LET’S HAVE A GREAT YEAR!
