Grade 12 - Science
Chemistry B - Semester 2 (Credit: 0.50)Chemistry is the study of how a set of substances with particular physical properties—
like solid paper and the oxygen in the air—can react with each other to form different
substances with entirely different properties—like gaseous water and carbon dioxide. In
most cases, these chemical changes result in an energy change as well, either giving
off energy or absorbing energy.
Chemistry is considered one of the core scientific disciplines because it is so practical
and widely useful in the modern world. The development of new types of materials, new
methods of producing or storing energy, or new methods of interacting with genetic
material all depend upon knowledge of chemistry.
In Chemistry B, you will learn about key types of chemical relationships and reactions,
including solutions, reversible reactions, acid-base reactions, thermochemical systems,
and electrochemical systems. You will use your knowledge to analyze new situations
and make qualitative and quantitative predictions. Finally, you will extend your chemical
knowledge into the areas of nuclear chemistry, organic chemistry, and biochemistry.
