Answer 2

$\huge\bold{Answer:-}$

Those reaction in which one element takes the place of another element in a compound are known as displacement reaction .

In general a more reactive element displaces a less reactive element from its compound .

Example :-

When a strip of zinc metal is placed in copper sulphate solution then zinc sulphate solution and copper are obtained. In this reaction ,Zinc metal displaces copper from copper sulphate compound so that copper is set free. The blue colour of copper sulphate solution fades due to the formation of zinc sulphate .A Red Brown deposit of copper metal is formed on the zinc strip. This displacement reaction takes place because zinc is more reactive than copper.
