Question

an example of a displacement/Single displacement reaction​

Answer 1

$\star\:\rm{Fe_2O_3(s)+2Al(s)\longrightarrow{}2Fe(l)+Al_2O_3(s)+Heat}$

• The above reaction is an example of a displacement/Single displacement reaction as aluminium displaced iron from its compound. This reaction is also called thermit reaction and is used for joining railway railway tracks, cracked machine parts, etc.

Additional Information :

Types of chemical reactions:-

1. Combination reaction.
2. Decomposition reaction.
3. Single Displacement reaction.
4. Double displacement reaction.

Single displacement reaction:-

• A reaction in which an atom or a group of atoms of a compound is displaced/replaced by another atom is known as single displacement reaction or simply, displacement reaction.
