·       Chemical Reactions

·       Inquiry question: What are the products of a chemical reaction?

·       Students:

·       investigate a variety of reactions to identify possible indicators of a chemical change

·       use modelling to demonstrate

·       the conservation of atoms in a chemical reaction (ACSCH042, ACSCH080) CThttps://syllabus.nesa.nsw.edu.au/wsimages/cca/n.png

·       conduct investigations to predict and identify the products of a range of reactions, for example:

·       synthesis

·       decomposition

·       combustion

·       precipitation

·       acid/base reactions

·       Predicting Reactions of Metals

·       Inquiry question: How is the reactivity of various metals predicted?

·       Students:

·       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

·       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?

·       Students:

·       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
