Question

A1br3 and 3K and 3K and 3KBr and A1 are an example of what reaction

Answer 1

Answer:

It is an example of single displacement reaction.

Explanation:

Single replacement reaction:

A single element replaces another element in a compound.

For example,

$AB+C\rightarrow A+BC$

The given reaction is as follows.

$AlBr_{3}+3K\rightarrow 3KBr+Al$

In the above reaction, aluminium bromide is dissociated into the $Al^{3+}and Br^{-}$ , these bromide ions are reacted with potassium atoms to form potassium bromide.

Here, only one element  displaces therefore, it is an single displacement reaction.
