What you'll learn
This course covers the things you'll need to know and be able to do for Achievement Standard 91166 (Chemistry 2.6) Demonstrate understanding of chemical reactivity.
In it you'll find answers to questions like:
- What are the factors that affect rates of chemical reactions?
- What is meant by changes in reaction rate?
- How do you describe the dynamic nature of equilibrium?
- How do you predict the effect of changes to an equilibrium system?
- How do you interpret and explain the nature of acid-base solutions?
- How do you write equations for proton transfer reactions between acids and bases?
- How do you explain the behaviour of strong and weak acids and bases in terms of the concentration of ions?
- How are conjugate acid/base pairs identified?
- How do you account for the acidic or basic properties of some salts?
- How do you calculate pH for aqueous solutions?
- How to compare the properties of solutions of strong and weak acids and bases?

What you'll learn
This course covers the things you'll need to know and be able to do for Achievement Standard 91164 (Chemistry 2.4) Demonstrate understanding of bonding, structure, properties and energy changes.
In it you'll find out how to:
- Determine the structure of atoms, ions and molecules and the attractive forces between them
- Describe bonding using Lewis structures
- Predict polarity of molecules from bond polarity and shape
- Use polar solvents – water and ethanol; non-polar hydrocarbon solvents (e.g. hexane, cyclohexane, mineral turpentine)
- Describe molecular, ionic, metallic and covalent network substances, and their physical properties
- Classify reactions as exothermic or endothermic
- Determine enthalpy changes
- Determine bond energies and how to calculate bond energy calculations.
