What you learn
The study of chemistry involves learning about all forms of matter. It focuses on the composition, structure, properties and change of matter by examining atoms and the bonds they form as elements and chemical compounds. There are 60 lessons in the HSC Study Lab HSC chemistry course, which corresponds to the 90 indicative hours of study required by the syllabus.Module 1 | Production of materials
-
Fossil fuels provide both energy and raw materials such as ethylene, for the production of other substances
-
Some scientists research the extraction of materials from biomass to reduce our dependence on fossil fuels
-
Other resources, such as ethanol, are readily available from renewable resources such as plants
-
Oxidation-reduction reactions are increasingly important as a source of energy
-
Nuclear chemistry provides a range of materials

Module 2 | Acidic environment
-
Indicators were identified with the observation that the colour of some flowers depends on soil composition
-
While we usually think of the air around us as neutral, the atmosphere naturally contains acidic oxides of carbon, nitrogen and sulfur. The concentrations of these acidic oxides have been increasing since the Industrial Revolution.
-
Acids occur in many foods, drinks and even within our stomachs
-
Because of the prevalence and importance of acids, they have been used and studied for hundreds of years. Over time, the definitions of acid and base have been refined.
-
Esterification is a naturally occurring process which can be performed in the laboratory

Module 3 | Chemical monitoring and management
-
Much of the work of chemists involves monitoring the reactants and products of reactions and managing reaction conditions
-
Chemical processes in industry require monitoring and management to maximise production
-
Manufactured products, including food, drugs and household chemicals, are analysed to determine or ensure their chemical composition
-
Human activity has caused changes in the composition and the structure of the atmosphere. Chemists monitor these changes so that further damage can be limited.
-
Human activity also impacts on waterways. Chemical monitoring and management assists in providing safe water for human use and to protect the habitats of other organisms.
