Chemistry 30

Course name and abbreviation:

Chemistry 30, CH30

Grade Level:

Grade 12

Summary of course content and activities:

Unit 1: Thermochemical Changes Chapters10-11

The primary objective of this unit is to gain an understanding of the relative amounts of energy that can be obtained from the three types of energy changes – phase change, chemical change, and nuclear change. In addition, information may be presented concerning some alternative forms of energy and the environmental problems caused by energy production.

Unit 2: Electrochemical Changes Chapters 12-13

In this unit, you will study electrochemical changes, analyzing the matter and energy changes within a system. The two major concepts developed in this unit are: many chemical changes involve the transfer of electrons, and energy is involved in electrochemical changes.

Unit 3: Equilibrium, Acids and Bases In Chemical Changes Chapters14-15

In this unit, the concept that change eventually attains equilibrium is expanded to a quantitative treatment in reaction systems involving ideal gases and acid and base solutions. You will apply stoichiometric methods to titration experiments, further explore indicators, and are introduced to buffer systems.

The course activities include reading, practice problems and virtual experiments.

Philosophy statement for and/or behind teaching this course:

You are surrounded by chemistry and things chemical. Your clothes, running shoes, cosmetics, toothpaste, the food you eat, the fuels you burn, are all chemical. You as an individual, make us of many chemical reactions everyday. Driving a car, racing downhill on a graphite snowboard, washing the dishes, or playing a video game, are all possible because of chemistry. Chemical reactions power your body’s physical activities and even your thoughts.

Unfortunately, environmental problems such as smog, toxic waste, industrial pollution and acid rain are also caused by chemicals that are in the wrong place at the wrong time. However, with a thorough knowledge of chemistry, and if the human race has the will, most pollution problems can be solved by improving the chemical processes which cause them or discover new chemical alternatives.

Chemistry deals with what things are made of, and how they behave or interact with other things around them. Thus chemistry deals with the composition, structure, and properties of matter as well as the changes or transformations that take place in matter. This course deals primarily with chemical change and the energy associated with these changes. Through the study of chemistry, you are given the opportunity to explore and understand the natural world and to become aware of the profound influence of chemistry in your life.

Major course goals:

Apply the principles of energy and matter conservation to chemical systems undergoing change; and use direct evidence and generalizations to predict the outcomes of chemical change; and relate chemical change principles to a variety of reaction applications.

Analyze physical, chemical and biological systems in terms of energy and matter forms, transfers, movement and conservation.

Explain the interrelationship between energy and chemical changes to matter and how energy is either released or absorbed as chemical bonds are rearranged and new substances are formed; and describe the practical applications of exothermic and endothermic changes.

Explain chemical changes to matter; and write balanced chemical equations to describe transformations and analyze them, quantitatively and qualitatively, to make predictions about the products formed or reactants consumed; and apply this knowledge to stoichiometric calculations in a variety of everyday and industrial situations.

Describe solution systems, including acids, bases and gases, quantitatively and qualitatively, and relate their properties to their uses.

Describe the diverse forms of matter, using models to illustrate bonding and structure, and using theories to explain the properties and behaviour of a variety of elements and organic and inorganic compounds and solutions, including acids, bases and gases.

Perform investigations and tasks of your own that have a few variables and yield direct evidence; collect, verify and organize data into tables, graphs and diagrams; and provide explanations based upon scientific theories and concepts.
