Question

Chemical equation for the reaction where iron oxide reacted with aluminium to form aluminium oxide and iron

Answer 1

This is a displacement reaction as aluminium displaces iron in iron(III)oxide to form aluminium oxide. Also it is a redox reaction as both oxidation of aluminium and reduction of iron is taking place. The equation can be written as: 2Al(s)+Fe2O3(s)→Al2O3(s)+2Fe(l)+heat.
