Answer 1

Answer:

$\huge\boxed{\sf Single \ displacement \ reaction}$

Explanation:

Displacement reaction:

• A reaction in which an element displaces or replaces another element of a compound is called a displacement reaction.

Types:

There are 2 types:

1. Single displacement reaction:

• If one element displaces 1 other element of a compound, it is called single displacement reaction.
• Example:  $CuSO_4 +Fe \longrightarrow \ FeSO_4 + Cu$
• Here, 1 element (Fe) displaces 1 other element (Cu) of a compound.

2. Double displacement reaction:

• If two elements in two compounds displace one another, it is called double displacement reaction.
• Example: $CuSO_4+NaOH \longrightarrow Cu(OH)_2 + Na_2SO_4$
• Here, Copper and sodium both displace each other.
