Description de cours

In this course, you will deepen your understanding of chemistry through the study of the properties of chemicals and chemical bonds; chemical reactions and quantitative relationships in those reactions; solutions and solubility; and atmospheric chemistry and the behaviour of gases. You will further develop your analytical skills and investigate the qualitative and quantitative properties of matter, as well as the impact of some common chemical reactions on society and the environment.

Note: This course is delivered online through My ILC. All lessons are in electronic form and can be downloaded and printed by the student if desired. All assignments must be submitted online using the assignment submission tool (part of My ILC). For special circumstances: Contact Learner Services.

Journal électronique

Le matériel supplémentaire

A scientific calculator (can display very large or very small numbers in scientific notation, and can do exponents).


    

Unit 1: Matter, Periodic Trends, and Chemical Bonding

The fascinating part of chemistry is that it can explain characteristics of everyday substances. Why, for example, is water (H2O) a liquid when every other two-atom compound of hydrogen is a gas? Why are some things, such as salt and sugar, solid while air is a gas? Why do some things dissolve in water and others do not? How will knowledge of the properties of materials benefit your own health and the health of the environment?

In this unit, you will review the atomic model and use it to predict how elements will combine to form chemical bonds. You will also examine the properties of common materials and consider how it may be possible to reduce any harmful impact on your health or the environment.

Unit 2: Chemical Reactions

Household products contain warning symbols, while, at your workplace, products used for cleaning or production carry WHMIS symbols. The substances we use in our daily lives can help us and at the same time harm us. We make extensive use of metals for jewellery, construction, and household objects yet producing these metals releases toxic substances such as cadmium, arsenic, sulphur dioxide, and mercury. All of these can endanger the health and safety of local populations.

Chemical reactions and their applications have significant implications for society and the environment through pollution control techniques (catalytic converter and smokestack scrubber systems) and pollution-causing industries (mining, smelting, paper manufacture, and electrical generation stations).

Fortunately, chemical reactions are both controllable and predictable and this knowledge can make us safer at home and at work.

Unit 3: Quantities in Chemical Reactions

Chemical reactions provide us with many things we take for granted in our daily lives. The plastic bags we carry groceries in, the fertilizer which was used to grow the vegetables we eat, even the clean drinking water we are used to getting from the tap in the kitchen. When chemical reactions are not controlled, they can result in disasters. Bhopal, India may be the most famous chemical disaster, but there are examples from closer to home. Understanding quantities in chemical reactions is an important part of remaining safe in a world of chemicals.

Unit 4: Solutions and Solubility

Water is an amazing substance. If not for the unique properties of water, the world would be a lot different. Specifically, the ability of water to dissolve other substances makes life as we know it possible. Canada has an abundance of fresh clean water compared to the rest of the world, but we still need to protect our water supply because it is not limitless. The ability of water to dissolve other substances also means water can become contaminated very quickly as well. In this unit, you will study the properties of solutions, including acids and bases, and learn how to do calculations related to solubility, concentration and chemical reactions.

Unit 5: Gases and Atmospheric Chemistry

When astronauts view the Earth from space they marvel at our blue planet. They also notice the very thin layer of the atmosphere that surrounds the Earth. This thin layer scatters blue light from the sunlight hitting it making the planet look blue from space. The atmosphere, made up of swirling gases, allows life to exist here. These gases allow us to breathe and protect us from the damaging rays of the sun. They also allow air planes to fly and keep the water in the oceans from evaporating too quickly. The atmosphere is critical to our survival, and yet, we constantly dump chemicals into it which have the capacity to destroy it.

Examining how temperature, pressure, volume, and the number of molecules of a gas are related will enable you to understand how gases behave. Knowledge of the behaviour of gases will help you understand how we are damaging our atmosphere and how we can repair it.
