YEAR 11 CHEMISTRY (QCE) SUBJECT OVERVIEW

CHEMISTRY is a course of study consisting of four units, completed over two years. Subject matter, learning experiences and assessment increase in complexity from Units 1 and 2 to Units 3 and 4 as students develop greater independence as learners. Only results for Units 3 and 4 will contribute to ATAR calculations. YR 11 COURSE OUTLINE UNIT FOCUS 1. Chemical Fundamentals – Structure, Properties and Reactions Topic One: Properties and structure of atoms Topic Two: Properties and structure of materials In Unit 1, students relate matter and energy in chemical reactions as they consider the breaking and reforming of bonds as new substances are produced. The properties of a material depend on, and can be explained by, the material’s structure. A range of models at the atomic and molecular scale enable explanation and prediction of the structure of materials, and how this structure influences properties and reactions.

Topic Three: Chemical reactions – reactants, products and chemical change 2. Molecular interactions and reactions Topic One: Intermolecular forces and gases Topic Two: Aqueous solutions and acidity Topic Three: Rates of chemical reactions 3. Equilibrium, Acids and Redox Reactions Topic One: Chemical equilibrium systems Topic Two: Oxidation and reduction

In Unit 2, students develop their understanding of the physical and chemical properties of materials including gases, water, aqueous solutions, acids and bases. Students explore the characteristic properties of water that make it essential for physical, chemical and biological processes on Earth, including the properties of aqueous solutions. They investigate and explain the solubility of substances in water, and compare and analyse a range of solutions. They learn how rates of reaction can be measured and altered to meet particular needs. In Unit 3, students explore the reversibility of reactions in a variety of chemical systems at different scales; acid-base equilibrium systems and their applications; the principles of oxidation and reduction reactions; and the production of electricity from electrochemical cells. Processes that are reversible will respond to a range of factors and can achieve a state of dynamic equilibrium, while contemporary models can be used to explain the nature of acids and bases, and their properties and uses.
