Question

Comment upon the following :
Displacement reactions help to predict the reactivity of elements. ​

Answer 1

Answer:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.

Answer 2

Answer:

Yes they do.

Explanation:

In displacement reactions, elements with comparatively higher reactivity only can replace comparatively lower reactive elements from their salts. Hence, displacement reactions help to predict the reactivity of elements.
