Curriculum content descriptions
identify patterns in synthesis, decomposition and displacement reactions and investigate the factors that affect reaction rates (AC9S10U07)
Elaborations
- defining and representing synthesis, decomposition and displacement reactions using a variety of formats such as molecular models, diagrams, and word and balanced symbolic equations
- identifying reaction type and predicting the products
- investigating synthesis reactions such as reaction of metals with oxygen, formation of water and sodium chloride; decomposition reactions such as those used to extract metals; and displacement reactions such as metal and acid, neutralisation and precipitation
- investigating the effect of a range of factors, such as temperature, concentration, surface area and catalysts, on the rate of chemical reactions
- investigating chemical reactions employed by First Nations Australians in the production of substances such as acids and ethanol
- investigating some of the chemical reactions and methods employed by First Nations Australians to convert toxic plants into edible food products
- examining reactions that are used to produce a range of useful products
