Energy and Matter in Chemical Change

Focusing questions

• How has knowledge of the structure of matter led to other scientific advancements?
• How do elements combine?
• Can these combinations be classified and the products be predicted and quantified?
• Why do scientists classify chemical change, follow guidelines for nomenclature and represent chemical change with equations?

Key concepts (POS)

• WHMIS and safe practices
• IUPAC nomenclature
• ionic and molecular compounds
• acids and bases
• evidence of chemical change
• writing and balancing equations
• law of conservation of mass and the mole concept
