Types of Chemical Reaction

Identify and describe four types of chemical reaction: combustion (burning in oxygen), oxidation (gain of oxygen), thermal decomposition (breaking down by heat), and displacement (more reactive metal replaces less reactive one)

How to tell they’ve got it

Tick these off as you see them — no test required.

Writes a word equation for each type of reaction with an example
Identifies the type of reaction from a given word equation or description
Explains what makes a displacement reaction happen (relative reactivity)
Distinguishes complete combustion (CO₂ and H₂O) from incomplete combustion (CO and soot)

Try this together

If your child saw iron going rusty and a candle burning, could they explain what type of chemical reaction is happening in each case — and write a simple word equation for one of them?

Builds on

Physical vs Chemical Changesages 11–13Types of chemical reaction are specific categories of chemical change — the physical/chemical distinction must come first

Metals vs Non-Metalsages 11–13Displacement reactions require understanding that metals differ in reactivity — metal properties provide the context

Unlocks

The Reactivity Seriesages 12–14Displacement reactions are a key application of the reactivity series — reaction types must be understood first

Acid Reactions & Saltsages 12–13Acid reactions are specific examples of chemical reaction types (neutralisation, displacement)

Reactions That Release or Absorb Heatages 12–13Energy changes are a property of chemical reactions — understanding reaction types gives context

Curriculum alignment

Candidate matches to official curriculum codes — machine-suggested, unreviewed (v0.1).

This skill sits beyond Year 6 in the Australian Curriculum, so no F–6 code is matched. It also sits beyond the NSW K–6 syllabuses. It also sits beyond Level 6 in the Victorian Curriculum.
