model the rearrangement of atoms in chemical reactions using a range of representations, including word and simple balanced chemical equations, and use these to demonstrate the law of conservation of mass (AC9S9U07)

Elaborations
  • identifying reactants and products in chemical reactions
  • using models and representations to show the rearrangement of atoms in chemical reactions
  • investigating chemical reactions in closed and open systems and relating data obtained to the law of conservation of mass
  • writing symbolic equations that are easy to balance and explaining, using the law of conservation of mass, and atoms, the rationale for balancing chemical equations
  • investigating why most elements are not found in their elemental state and processes which are used to obtain the element
  • predicting how ideas of green chemistry such as minimising the amount of unusable waste products, energy use and using more environmentally friendly chemical processes will affect the environment
General capabilities
  • Critical and creative thinking Critical and Creative Thinking
