The thermite reaction between aluminium powder and iron(III) oxide is highly exothermic and is represented by the following equation:
2Al+Fe2O3→Al2O3+2Fe 2\text{Al} + \text{Fe}_2\text{O}_3 \rightarrow \text{Al}_2\text{O}_3 + 2\text{Fe} 2Al+Fe2O3→Al2O3+2FeWhat does this reaction show about the reactivity of iron compared to the reactivity of aluminium?
Why is this reaction described as a displacement reaction?
State two reasons why the term oxidation applies to aluminium in this reaction.
Although this reaction is highly exothermic, it only begins after initial heat energy is supplied. State how this heat energy is typically supplied in a laboratory demonstration of this reaction.
