Types of Chemical Reaction

Science · Matter & Materials · conceptual

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)

What mastery looks like

  • 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)

Check your understanding

If Types of Chemical Reaction 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?
