Chemistry

Course summary

Chemistry is the study of all chemical substances and how to change one chemical into another. The food you eat, the air you breathe, your own body and the plants and streets around you are all made of chemicals. As consumers demand less expensive products, Chemistry helps to decrease economic costs; and as communities demand a safer environment, Chemistry helps to decrease pollution. Gone are the days that poisonous red lead oxide is used to colour cheese, or to sweeten cider; and now we do not put toxic arsenic in cosmetics; nor do we use lead in white paint, or make CFCs that destroy the ozone layer. These chemicals were used mostly out of ignorance, so with the development of new understanding in Chemistry, a safer world is built.
