Revision
Revision checklist
Can you explain each of these out loud, without looking? If not, re-read that lesson.
- Acids with Metals and Carbonates: Write equations for acids reacting with metals and carbonates.
- Making Salts: Prepare pure salts by reacting acids with bases and carbonates.
- The Reactivity Series: Use the series to predict displacement and extraction reactions.
- Energy in Reactions: Distinguish exothermic and endothermic reactions.
- Read each lesson's summary and re-do its practice questions from memory.
