🧪 Chapter 1: Chemical Reactions and Equations

A chemical reaction occurs when one or more substances change into new substances. Chemical equations represent these reactions using symbols and chemical formulas.

Example of a balanced chemical equation:

2H₂ + O₂ → 2H₂O

Important concepts include balancing equations, combination reactions, decomposition reactions, displacement reactions, double displacement reactions, oxidation, reduction and corrosion.

Exam Tip: Practise balancing chemical equations and identifying reaction types. Understand the concepts instead of memorising answers alone.
