GCSE Combined Science (AQA Trilogy): Chemistry
This course provides comprehensive coverage of the Chemistry component of the AQA GCSE Combined Science: Trilogy specification (8464). It is designed to equip you with the precise scientific knowledge, key definitions, and practical understanding needed to achieve a high grade in your exams. The course is structured into ten distinct topics, matching the AQA specification, and includes detailed guidance on all six required practicals. Because this is an audio-first course, we focus on clear explanations and memorable phrases that are perfect for exam answers. Through targeted retrieval practice, you will master core concepts, from atomic structure to the sustainable use of resources. Please note, to be fully prepared for your exam, you should supplement this audio course with written practice, especially for balancing equations, drawing diagrams, and attempting past paper questions.

10 items
AQA GCSE Combined Science: Atomic Structure and the Periodic Table
Covers the fundamental concepts of atomic structure, including the historical development of the atomic model, subatomic particles (protons, neutrons, electrons), atomic number, mass number, and isotopes. It details electron configuration for the first 20 elements and explores the structure and development of the periodic table, focusing on the properties and trends of Group 1 (alkali metals), Group 7 (halogens), and Group 0 (noble gases) as required for the AQA Combined Science Trilogy specification.
AQA GCSE Combined Science: Bonding, Structure, and Properties
Explores the three main types of chemical bonding: ionic, covalent, and metallic. This deck explains how to represent bonding and links the type of bonding and structure to the physical properties of substances. It covers ionic compounds, simple molecules, giant covalent structures (including diamond, graphite, graphene, and silicon dioxide), fullerenes, metals, and alloys. This deck strictly adheres to the AQA Combined Science Trilogy specification.
AQA GCSE Combined Science: Quantitative Chemistry
Introduces the quantitative aspects of chemistry as required for the AQA Combined Science Trilogy specification. This deck covers calculating relative formula mass (Mr), the law of conservation of mass, and balancing simple chemical equations. It introduces the concept of the mole in relation to mass and Mr, and covers calculations for the concentration of solutions in grams per cubic decimetre. It also provides a conceptual understanding of limiting reactants.
AQA GCSE Combined Science: Chemical Changes
Covers the reactivity of metals, including the reactivity series, displacement reactions, and the extraction of metals using carbon. It details the reactions of acids with metals, metal oxides, hydroxides, and carbonates. The deck explains the pH scale, neutralisation, and the distinction between strong and weak acids. It also covers the principles of electrolysis for molten ionic compounds and aqueous solutions. This deck includes Required Practical 1 (Making a Soluble Salt) and Required Practical 2 (Electrolysis of Aqueous Solutions).
AQA GCSE Combined Science: Energy Changes
Focuses on energy changes in chemical reactions. This deck defines and provides examples of exothermic and endothermic reactions. It introduces reaction profiles, explaining how to interpret and label the activation energy and the overall energy change (enthalpy change) for both types of reaction. This deck also covers Required Practical 3 (Investigating Temperature Changes in Reacting Solutions).
AQA GCSE Combined Science: The Rate and Extent of Chemical Change
Explores the factors that control the speed of chemical reactions, including temperature, concentration, pressure, and surface area, as well as the role of catalysts. The deck explains these effects using collision theory. It also covers reversible reactions and the concept of dynamic equilibrium, including how changes in conditions (temperature, pressure, concentration) can shift the position of equilibrium. This deck includes Required Practical 4 (Investigating How Concentration Affects Reaction Rate).
AQA GCSE Combined Science: Organic Chemistry
Introduces the chemistry of carbon compounds derived from crude oil. This deck covers hydrocarbons, the process of fractional distillation to separate crude oil, and the properties of the first four alkanes. It explains the process of cracking to produce more useful hydrocarbons, including alkenes. The properties and reactions of alkenes, including the test for unsaturation using bromine water, are also covered as required by the AQA Combined Science Trilogy specification.
AQA GCSE Combined Science: Chemical Analysis
Covers the techniques used to identify substances. This deck defines pure substances and formulations. It details the method of paper chromatography, including the calculation of Rf values. It also provides the chemical tests required to identify hydrogen, oxygen, carbon dioxide, and chlorine gases. Finally, it covers the flame tests and precipitate tests used to identify specific metal ions, and the tests for carbonate, halide, and sulfate ions. This deck includes Required Practical 5 (Paper Chromatography).
AQA GCSE Combined Science: Chemistry of the Atmosphere
Explores the composition of the Earth's current atmosphere and theories about its evolution. This deck covers the greenhouse effect, the roles of greenhouse gases like carbon dioxide and methane, and the link between human activities and climate change. It also discusses the concept of a carbon footprint and ways to reduce it, as well as the formation and environmental impact of atmospheric pollutants from combustion, such as carbon monoxide, sulfur dioxide, and oxides of nitrogen.
AQA GCSE Combined Science: Using Resources
Covers the sustainable use of Earth's resources, including the difference between finite and renewable resources, water treatment, Life Cycle Assessments (LCAs), and Required Practical 6 (Analysis and Purification of Water Samples).
