GCE O-Level Q&A Chemistry

Key Features

• 1. Extensive use of diagrams throughout the book
• 2. Summary Lists of Important Facts
  Eg. Summary of Common Electrolysis Reactions in Section 4.4, page 136 (Electrolysis).
  Eg. Lists of Important Facts to be memorised in Section 9 (Metals).
• 3. Consolidation Exercises (before Main Exercises at end of each Section) to help you remember important concepts. Especially in long/difficult sections like section 3, 6, 7
• 4. Extensive set of exercises at the end of each Section Each Exercise Set comes in two parts:
• Part I consists of Multiple Choice Questions with 4 choices: A,B,C,D
• Part II consists of Structured Questions
• 5. Full and Complete answers to Part II Questions of each section. These are to be found in Appendix A : Answers
• 6. Two appendices to complete your understanding of Chemistry:
• Appendix C covers the main conventions used in naming chemical compounds.
• Appendix D covers the colours of chemical substances. This is especially useful in answering questions on colour changes occurring in a chemical reaction.
• 7. A Periodic Table of Elements in Appendix B.
