Course Description:
There are four main units of study in Chemistry 20:
Unit A: The Diversity of Matter and Chemical Bonding
The major focus of this unit is to relate theories about bonding to the properties of
matter and to develop explanations and descriptions of structure and bonding through
scientific models. You will investigate ionic and molecular substances.
Key Concepts:






Chemical bond
Ionic bond
Covalent bond
Electronegativity
Polarity
Valence electron





Intramolecular and
intermolecular forces
Hydrogen bond
Electron dot diagrams
Lewis structures
VSPER Theory
Unit B: Forms of Matter: Gases
You will expand your knowledge of the nature of matter through the investigation
of the properties and behaviour of gases.
Key Concepts:






Celsius and Kelvin
temperature scales
Absolute zero
Real and ideal gases
Law of combining volumes
Charles’ Law
Boyle’s law



Ideal gas law
Standard temperature and
pressure (STP)
Standard ambient
temperature and pressure
(SATP)
Unit C: Matter as Solutions, Acids, and Bases
In this unit, you will gain insight into the nature of matter through an investigation
of change in the context of solutions, acids and bases.
Key Concepts:








Homogeneous mixtures
Solubility
Electrolyte/non-electrolyte
Concentration
Dilution
Strong acids and bases
Weak acids and bases
Monoprotic/polyprotic acid






Monoprotic/polyprotic base
Arrhenius (modified) theory of
acids and bases
Indicators
Hydronium ion/pH
Hydroxide ion/pOH
neutralization
Unit D: Quantitative Relationships in Chemical Changes
We will focus on chemical change and the quantitative relationships contained in
balanced chemical equations. They are required to use stoichiometric principles and
mathematical manipulation to predict quantities of substances consumed or produced in
chemical reaction systems.
Key Concepts:











Chemical reaction equations
Net ionic equations
Spectator ions
Reaction stoichiometry
Precipitation
Limiting and excess reagents
Actual, theoretical, and percent yield
Titration
End point
Equivalence point
Titration curves for strong acids and base

Materials/Expectations
o Blue or black pen for taking notes
o Marking Pen (red preferably)
o Pencil/Eraser
o Calculator
o 3-ring binder, loose leaf paper, and graph paper
o Coiled notebook for notes (optional)
** Does not replace the 3-ring binder as there will be handouts. If you would
rather take notes on loose leaf, paper just the 3-ring binder is fine.

All materials must be brought to every class
Any missed assignments or tests need to be made up on the student’s
initiative. If you know ahead of time you will be absent, please let me know!
Assessment and Evaluation:
Chapter reviews, quizzes (often open book), unit tests, and the final exam will be
designed to evaluate your knowledge in Chemistry 20. Your term mark will be obtained
using the following weighting and categories:
Chapter Reviews
Quizzes
Unit Tests
Final Exam

Five to eight days will be used at the end of the year to review the course material prior to
the final exam.
