Chemistry (SCH3U-C)

Description de cours

This course enables you to deepen your understanding of chemistry through the study of organic chemistry, the structure and properties of matter, energy changes and rates of reaction, equilibrium in chemical systems, and electrochemistry. You will further develop your problem-solving and investigation skills as you investigate chemical processes, and will refine your ability to communicate scientific information. Emphasis will be placed on the importance of chemistry in everyday life and on evaluating the impact of chemical technology on the environment.

You will analyze 3D models of hydrocarbons and complex molecules, and view video clips featuring nuclear power, hydroelectric power and fossil fuel power.

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.

Unit 1: Structure and Properties of Matter

A good place to begin this course is to look at the structure of the fundamental building block of matter—the atom—as you will do in Lesson 1. You can then consider different ways in which atoms link together to form the substances around us. In the lessons that follow, you will learn that the chemical and physical properties of these substances are a direct result of how substances are put together. In other words, the properties of any substance depend on the chemical bonds within that substance. In this unit, you will consider two types of bonding. Understanding the nature of bonding in a substance is the first key step in being able to explain the substance’s properties.

This understanding is critical because properties ultimately determine how the substance is used, as well as its potential impact on human health and the environment. Our knowledge of the atom has led to many amazing technologies. One of the most useful applications of these technologies is medical imaging. You will begin your study of the atom by first considering some medical imaging techniques such as the X-ray, a type of ray that can safely penetrate the body to reveal its inner secrets.

Unit 2: Organic Chemistry

This unit will expand your knowledge of chemicals that contain carbon, such as the compounds in foods, plastics, and petroleum. You will look at the hazards and benefits of some of these compounds and consider ways to reduce their negative impacts. In order to do this, you need to understand the properties of these compounds and some of the common reactions that can create or modify them. One of the most useful carbon compounds is oil. Oil is a mixture of carbon-based compounds. Many of these compounds are the raw materials used to make many of the consumer products we rely on.

After completing this unit, you will be able to assess the environmental footprint of an organic compound and propose a plan of action to reduce its impact. You will investigate common reactions of organic compounds and explore the properties of organic compounds and see how these properties are related to their structure.

Unit 3: Oxidation Reduction Reactions and Energy

So far in this course, you’ve learned that the tiny electron is responsible for all of the chemical reactions that happen in the substances around us. The electron arrangement of the atom of an element determines the element’s reactivity. Many chemical reactions occur as a result of electron transfers from one reactant to another. Chemical reactions, in which one entity loses electrons, while another gains electrons, are called oxidation reduction reactions (redox reactions). In the first half of this unit, you will study the nature of redox reactions, as well as their applications. The second half of the unit focuses on the energy changes associated with these reactions.

Unit 4: Rates of Reactions and Chemical Systems

Whether you realize it or not, chemical reactions play a critical role in all aspects of your life. Chemical reactions occur throughout your body and the environment. You may not have thought too much about how chemical reactions happen. For instance, have you ever wondered whether there are changes in the rate at which reactants are turned into products? Or thought about how often chemical bonding occurs in atoms and molecules, which you can’t see? Reaction equations don’t give you these details.

A typical equation resembles an uninformative math equation, except for the fact that it has arrows instead of equal signs: reactants turn into products, represented by an equation with an “→.” But reactions happen at different rates—some fast, some slow—and there are predictable reasons for these different reaction rates. This unit will help you learn about rates of reactions and chemical systems.

Unit 5: Equilibrium Applications

This unit continues the study of equilibrium reactions. You will learn about equilibrium in saturated solutions and in acid–base chemistry. You will be using the same terminology that was introduced in the previous unit, writing equilibrium expressions, and calculating equilibrium constants and equilibrium concentrations, using the ICE chart. There are many applications of equilibrium reactions: industrial chemistry, environmental chemistry, and the chemistry of the human body.

The overall focus of this unit is the various ways in which equilibrium reactions are applied to medical and health issues. The final lesson will provide you with explanations of situations in which an understanding of equilibrium reactions is necessary in diagnosing, treating, and preventing a number of human health concerns.

At the end of the unit there is a Practice Test. It will help you prepare for the Final Test.
