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
conduct investigations to predict and identify the products of a range of reactions, for example:
synthesis
decomposition
combustion
precipitation
acid/base reactions
acid/carbonate reactions
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?
conduct practical investigations to compare the reactivity of a variety of metals in:
water
dilute acid
oxygen
other metal ions in solution
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:
ionisation energy
atomic radius
electronegativity
apply the definitions of oxidation and reduction in terms of electron transfer and oxidation numbers to a range of reduction and oxidation (redox) reactions
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
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:
temperature
surface area of reactant(s)
concentration of reactant(s)
catalysts
investigate the role of activation energy, collisions and molecular orientation in collision theory
explain a change in reaction rate using collision theory
