Covers separate Chemistry and Trilogy at Foundation and Higher levels. Over 1100 marks worth of examination style questions. Answers provided for all questions within the book. Illustrated topics to improve memory and recall. Specification references for every topic. Examination tips and techniques.
Chapter One:
This chapter introduces the fundamental ideas of AQA GCSE Chemistry 8462/8464. It focuses on the idea that chemistry is an experimental science which requires an understanding of matter, its properties and its changes. It focuses on the concept of “state of matter” and explains how different states of matter react differently. It also explains how changes to states of matter can occur and why understanding them is important. It gives real-world examples of how chemistry can be applied in everyday life, such as how water molecules can evaporate from a surface if heated; how a gas can be created when a liquid evaporates; and how a solid can form when a liquid cools. It also provides a useful overview of the topics which will be discussed more in depth in upcoming chapters, such as acids and bases, chemical reactions, and the Periodic Table.
Chapter Two:
This chapter introduces the concept of the Periodic Table of Elements and explains how it is organized. It focuses on the organisation, ordering, and elements which make up the Periodic Table. It also explains the different groups and periods within the table, and how the elements contained within each group are related. It uses real-world examples to illustrate the different properties of elements, such as the differences between metals, non-metals, and metalloids. It also explains how the Periodic Table can be used for calculations, such as determining the mass number and isotopic composition of elements.
Chapter Three:
This chapter introduces the concept of atomic structure and explains how different elements are composed. It focuses on how elements are made up of protons, neutrons, and electrons and how this arrangement affects their properties. It also explains the different types of Bondings which occur between these particles and explains why different elements form different compounds. It uses diagrams and equations to illustrate the different types of bonding and how they impact the properties of elements. It also provides real-world examples of different compounds formed by specific elements, such as water molecules formed from hydrogen and oxygen atoms.
Chapter Four:
This chapter introduces the concept of chemical reactions and explains the importance of understanding them. It focuses on the different types of chemical reactions, such as exothermic and endothermic reactions, and the factors which can affect them, such as temperature and concentration. It also explains how to classify and balance chemical equations and how to interpret them. It uses real-world examples to illustrate the different chemical equations, such as the combustion of ethanol which produces water and carbon dioxide. It also provides useful tips on how to remember key components of the equations.
Chapter Five:
This chapter introduces the concept of acids and bases and explains how they interact with each other. It focuses on the different pH scales and how they are used to denote how acidic or basic a substance is. It also explains the different ways in which acids and bases can react and how these reactions are useful in different situations. It provides real-world examples of how acids and bases can be used, such as in the preparation of different types of food and cleaning solutions.It also provides useful tips on how to remember key components of the equations.
Chapter Six:
This chapter introduces the concept of organic chemistry and explains how it is used in everyday life. It focuses on the different types of hydrocarbons which can form compounds and the different ways in which they can be used. It also explains the different reactions which can occur when hydrocarbons are mixed with oxygen. It provides real-world examples of how organic compounds can be used, such as in fuels and plastics. It also explains the importance of understanding organic compounds and the different processes used to produce them.
