91164 Bonding, Structure and Energy
This course covers the things you'll need to know and be able to do for Achievement Standard 91164.
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.
How you'll learn
There are a variety of ways you can learn and interact with the materials in this course.
Self-paced learning – the material is set up so you can learn at your own pace. Although there are 'suggested' times for each page, they're just a guideline - plan your learning to suit you.
Practice activities – throughout this course there are short activities. These activities are for you, not for someone to mark them. These activities give you a great chance to practice what you've learned and compare your answer to the model feedback. Look at the feedback carefully to see if you have missed out any aspects from your answer.
Submitting photos – sometimes people find it easier to scribble down a diagram or show their working with pen and paper. No problem! You can still store all your working and diagrams with the activity. That way you'll be able to refer back to your answers when you're revising. Simply take a photo of your work and upload it with the relevant activity.
