Iron oxide reacted with aluminium in this reaction iron and aluminium trioxide are formed express this reaction by chemical equation and balance the

equation step wise


Iron oxide reacts with alluminium to form alluminium trioxide and iron. This is called thermite reaction and it is exothermic.

Chemical Equation:
Fe₂O₃ + Al → Al₂O₃ + Fe

For balancing:
1. Number of Al on right side is 2 and left side is 1. So write 2Al on left side.
Fe₂O₃ + 2Al → Al₂O₃ + Fe
2. Number of Fe on left side is 2 and right side is 1. So write 2Fe on right side.
Fe₂O₃ + 2Al → Al₂O₃ + 2Fe
3. Number of O on right side is 3 and left side is also 3. No need to change anything for it.

So final equation becomes
Fe₂O₃ + 2Al = Al₂O₃ + 2Fe
