Unit A: Chemical Changes
Themes: Matter, Change and Energy
Overview: Chemical changes involve a change in energy. In order for students to understand how numerous useful materials are produced, they need to develop an understanding of concentrations of aqueous solutions, oxidation-reducation (redox) processes and the characteristics of hydrocarbons. Economically important industries in Alberta and other parts of Canada are based upon the application of chemical principles.

This Unit Builds On:
- Science 10, Unit A: Energy and Matter in Chemical Change.
Course Focus: We will spend ~25% of the course on this unit.
Students Will:
- Investigate aqueous solutions to determine conductivity and to calculate concentration.
- Explain oxidation, reduction and spontaneity and apply this knowledge to voltaic and electrolytic cells and to industrial processes.
- Describe the properties of simple hydrocarbons and describe hydrocarbon-based industrial processes that are important in Alberta.
Key Concepts:
- electrolytes
- non-electrolytes
- concentration
- dilution
- oxidation/anode
- reduction/cathode
- spontaneity
- applications of oxidation-reduction reactions
- voltaic cell
- electrolytic cell
- Naming and drawing structural formulas for saturated/unsaturated hydrocarbons (containing up to eight carbon atoms in the parent chain)
- Hydrocarbon reactions important to industry in Alberta
