· Chemical Reactions
· Inquiry question: What are the products of a chemical reaction?
· investigate a variety of reactions to identify possible indicators of a chemical change
· use modelling to demonstrate
· the rearrangement of atoms to form new substances
· the conservation of atoms in a chemical reaction (ACSCH042, ACSCH080)
· conduct investigations to predict and identify the products of a range of reactions, for example:
· acid/carbonate reactions (ACSCH042, ACSCH080)
investigate the chemical processes that occur when Aboriginal and Torres Strait Islander Peoples detoxify poisonous food items
· construct balanced equations to represent chemical reactions
· Predicting Reactions of Metals
· Inquiry question: How is the reactivity of various metals predicted?
· construct a metal activity series using the data obtained from practical investigations and compare this series with that obtained from standard secondary-sourced information
· analyse patterns in metal activity on the periodic table and explain why they correlate with, for example:
· conduct investigations to measure and compare the reduction potential of galvanic half-cells
· construct relevant half-equations and balanced overall equations to represent a range of redox reactions
· predict the reaction of metals in solutions using the table of standard reduction potentials
· predict the spontaneity of redox reactions using the value of cell potentials (ACSCH079, ACSCH080)
· Rates of Reactions
· Inquiry question: What affects the rate of a chemical reaction?
· conduct a practical investigation, using appropriate tools (including digital technologies), to collect data, analyse and report on how the rate of a chemical reaction can be affected by a range of factors, including but not limited to:
· investigate the role of activation energy, collisions and molecular orientation in collision theory
· explain a change in reaction rate using collision theory
