Student Unit Guides are perfect for revision. Each guide is written by an examiner and explains the unit requirements. This guide offers advice on preparing for the Edexcel Unit 3 and Unit 6 Chemistry Laboratory Skills assessments. The Content Guidance section outlines what you may be asked to do in the internally assessed practicals. The four skills required for A-level practical chemistry are described. Practice examples and worked examples with examiner's comments will help you understand precisely what you have to learn, the skills required and the potential pitfalls. The Questions and Answers section provides examples of the types of experiments and questions that you will be given in Units 3 and 6. It also contains answers to these test questions and to the practice examples.
This is a resource book for IGCSE Chemistry concepts for students to clearly understand and explain all key concepts of IGCSE Chemistry. The book explains how students should approach Chemistry in IGCSE board exams and for intensive revision of concepts. It is also useful for new teachers as it clearly explains and illustrates through examples and diagrams based on pattern of questions for various secondary boards. The book contains comprehensive lecture notes and key points as asked in the exams for six chapters along with EXAM STYLE QUESTIONS at the end of each chapter for thorough practice. These questions are based on three paper types of IGCSE chemistry components (papers) viz MCQ type, structured short and long answer questions. Also instructional lines are given after each question to enable the learners to draft objective responses to the given questions. The topics included in the book are matter, atomic structure, formulae, valencies, equations and balancing, moles, periodic table and bonding are clearly explained by solved examples. The book is highly recommended for students of other international secondary chemistry curricula such as O-level, Edexcel GCSE secondary, IB MYP.: Contents: Chapter-1 Particulate Nature of Matter: States of Matter: Arrangement of particles in matter: Kinetic Particle Theory: Conversion of States: Heating Curve: Cooling Curve: Brownian motion: Exam Style Questions: Chapter-2 Measurement Experimental Techniques-: Measurement: Pure Substances: Criteria for Purity: Difference between compounds and mixtures: Homogenous mixtures: Heterogeneous mixtures: Separation Techniques: Decantation: Filtration: Sublimation: Chromatography: Distillation: Fractional distillation: Crystallization: Centrifugation: Exam Style Questions: Chapter-3 Structure of Atom: Atoms: Elements: Discovery of sub atomic particles: Models of Atom Structure and Stability Atom and Ion: Isotopes: Radio Isotopes: Electronic Arrangement: Exam style Questions: Chapter-5 Stoichiometry: Elements: Compounds: Chemical Formula: Word Equation: Symbol Equation: Balancing Equation: Relative Atomic Mass: Naming Compound: Information from a chemical equation: Definition of Mole: The mole concept: Molar Mass: Important Formula: Limiting reagent: Reacting Masses: Reacting masses and ratios: Molar Volumes: Concentration of Solutions: Water of Crystallization Empirical and Molecular Formula Percentage Yield: Percentage Purity: Solved Examples of all the concepts: Practice Questions: Exam style Questions: Chapter-6 Chemical Bonding: Chemical Bond: Ionic Bond: Covalent Bond: Metallic Bond: Coordinate Bond: Giant Structures: Formula of positive and negative ions: Exam style Questions
