Fe2O3 + 2Al → Al2O3 + 2Fe The above reaction is an example of a (i)Combination reaction (ii)Double displacement reaction (iii)Decomposition reaction (iv)Displacement reaction Solution:

(iv)Displacement reaction

Reason: To create aluminium oxide, oxygen from ferrous oxide is transferred to aluminium metal. Aluminum is a more reactive metal than Fe in this reaction. Al will therefore remove Fe from its oxide. One of the elements displaces another in a chemical process known as a displacement reaction. More reactive metal here replaces less reactive metal. It is known as a single displacement reaction because only one displacement is taking place
