Contextual Outline
Humans have always exploited their natural environment for all their needs including food, clothing and shelter. As the cultural development of humans continued, they looked for a greater variety of materials to cater for their needs. The twentieth century saw an explosion in both the use of traditional materials and in the research for development of a wider range of materials to satisfy technological developments. Added to this was a reduction in availability of the traditional resources to supply the increasing world population. Chemists and chemical engineers continue to play a pivotal role in the search for new sources of traditional materials such as those from the petrochemical industry. As the fossil organic reserves dwindle, new sources of the organic chemicals presently used have to be found. In addition, chemists are continually searching for compounds to be used in the design and production of new materials to replace those that have been deemed no longer satisfactory for needs. This module increases students’ understanding of the implications of chemistry for society and the environment and the current issues, research and developments in chemistry.

Study Guide -‐ 9.2.A Synthetic Polymers
9.2.A Conceptual Outline
A polymer is a large molecule (macromolecule) composed of repeating structural units. These sub-‐units are called monomers and are typically connected by covalent chemical bonds. Although the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of compounds comprising both natural and synthetic materials with a wide variety of properties. Polymeric materials play an essential and ubiquitous role in everyday life. This role ranges from familiar synthetic plastics and elastomers to natural biopolymers such as nucleic acids, proteins and cellulose that are essential for life. Most commonly, the continuously linked backbone of a polymer used for the preparation of plastics consists mainly of carbon atoms. A simple example is polyethylene whose repeating unit is based on ethylene monomer.

Study Guide -‐ 9.2.B Biological Polymers
9.2.B Conceptual Outline
Fossil fuels are non-‐renewable resources, available in fixed amounts. Human activity has the potential to completely exhaust reserves of fossil fuel resources. Biomass, organic matter produced by photosynthesis in plants, is a renewable resource. Biomass consists mostly of cellulose and can be used and then formed again from its products by the input of solar energy during photosynthesis. If the matter involved is recycled, biomass could be a source of raw materials for as long as the sun supplies solar energy.
Petrochemicals are chemicals made from compounds in petroleum or natural gas. Currently Australia has petroleum reserves that will last about ten years and natural gas reserves that will last about one hundred years. Fossil fuels have taken hundreds of millions of years to accumulate. Over 95% of fossil fuel is burnt as a source of energy and once burnt, fossil fuels are no longer available. Less than 5% of fossil fuel is used to make plastics and only a small percentage of that plastic is recycled. If energy and material needs are to be met in the future, alternative sources will be needed as fossil fuel sources are used up.
In this topic students:
Identify and describe examples of condensation reactions, Describe the structure, formation and properties of cellulose, Assess potential of cellulose as a replacement for compounds currently obtained from petrochemicals, and Describe the production, properties and use of a named biolpolymer.

9.2.C Conceptual Outline
Humans discovered ethanol not long after they figured out how to put fire to good use. Today, ethanol has many uses: we drink it; dissolve solutes in it, use it in food, industry and other manufacturing; and blend it with petrol to make a sustainable and renewable transport fuel.
Ethanol belongs to the homologous series of alkanols, each with a hydroxyl (-‐OH) functional group. It can be made by fermenting the sugars found in plants using yeasts (fungi) and bacteria. Ethanol can be used as a fuel for vehicles in its pure form as a replacement for petrol, but it is usually blended with petrol so as to improve vehicle emissions and make motor fuel more sustainable.
In this topic students:
Describe the properties of ethanol and relate them to its use, Describe and write equations for the dehydration, fermentation and combustion of ethanol, and Assess the potential of ethanol as an alternative to petrol.

Study Guide -‐ 9.2.D Electrochemistry
9.2.D Conceptual Outline
The term oxidation was originally used to describe reactions in which an element combines with oxygen. After electrons were discovered, chemists extended the definition of oxidation to involve the transfer of electrons from one atom to another. Because electrons cannot be created or destroyed, the species losing electrons is said to be oxidised while the species gaining electrons is said to be reduced.
If the electrons from an oxidation reaction can be made to flow around a circuit to the site of reduction, we have a galvanic cell or battery. These cells convert chemical energy to electrical energy and rely on oxidation-‐reduction reactions.
In this unit you will learn to:
Recognise oxidation-‐reduction reactions Assigning oxidation states to species to determine if oxidation or reduction has occurred Use metal displacement reactions to put metals into an order or activity Describe and construct galvanic cells and calculate their theoretical cell potentials Compare different types of galvanic cells

Study Guide -‐ 9.2.E Nuclear Chemistry
9.2.E Conceptual Outline
Radioactive materials that release alpha, beta or gamma radiation have a range of uses in both industry and medicine. They are used as diagnostic tools in both industry and medicine and are used in the treatment of diseases such as cancer in medicine. Radioisotopes have an unstable nucleus and release energy by ejecting particles or electromagnetic radiation from the nucleus. They are made in nuclear reactors where radioactive decay processes are artificially induced by bombarding nuclei with neutrons. Some radioisotopes can be made by smashing the nuclei of atoms together in particle accelerators through a process known as nuclear fusion. Many artifically synthesised elements called transuranic elements have been made in this way in particle accelerators.
In this unit you will learn to:
Describe the structure of the nucleus using atomic notation Distinguish isotopes of an element and represent them using atomic notation Explain what makes a nucleus unstable Describe the processes of alpha, beta and gamma decay using chemical equations Describe the properties of alpha, beta and gamma radiation Outline ways to detect radiation Describe how transuranic elements are produced Describe some uses of radioisotopes in industry and medicine
