Let's review!
In this unit you sharpened your equation-writing skills, then learned the five types of reactions: synthesis, decomposition, single displacement, double displacement and combustion. For each type you learned rules to predict products: ion charges, oxide families, the activity and halogen series, the solubility table, gas-forming patterns, neutralization, and complete versus incomplete combustion. You practised lab skills: WHMIS safety, testing for products, planning an investigation and reporting results. Finally, you analysed industrial reactions that affect health and the environment and assessed chemical solutions such as scrubbers, liming and catalytic converters.

How to use this review
Do two or three sections at a time. Keep your periodic table, ion list, activity series, halogen series and solubility table beside you, just as you would on a test. For each prediction, say the reaction type out loud first. Write every formula from ion charges, include states, and balance. For every question you get wrong, write down why (wrong type? wrong formula? forgot NR? not balanced?) and go back to that lesson's worked examples. Finish with the 10-question quiz.
