Hint: In a chemical, a displacement reaction occurs where an atom or a group of atoms is replaced by another atom. As iron is applied to a copper sulphate solution, for example, the copper metal is displaced. A + B-C \[ \to \] A-C + B. When A is more reactive than B, the equation above is true.


Complete answer:
In a chemical, a displacement reaction occurs where an atom or a group of atoms is replaced by another atom. As iron is applied to a copper sulphate solution, for example, the copper metal is displaced. A + B-C \[ \to \] A-C + B. When A is more reactive than B, the equation above is true.
Aluminium + Iron (III) oxide gives Aluminium oxide and iron
\[3F{e_3}{O_2}\; + {\text{ }}4Al{\text{ }} \to {\text{ }}2A{l_2}{O_3}\; + {\text{ }}6Fe\]
Since aluminium has replaced iron from its compound, Ferric oxide, it is a displacement reaction.
Aluminium oxide and iron are produced when iron(III) oxide reacts with aluminium.
A significant amount of heat is released, which is sufficient to melt oxygen and aluminium.
Aluminum has a higher reactivity than iron, and it can displace iron from iron(III) oxide.
The aluminium oxidises the iron(III) oxide and eliminates the oxygen.

Note:
A salt metathesis reaction, also known as a double substitution reaction or a double displacement reaction, is a chemical reaction in which two reacting chemical species exchange bonds, resulting in the formation of compounds with related or equal bonding affiliations.
