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)
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
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?

This concept
Check understanding
- 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)
