Question

Zn + H2O ---- X+Y. Name the x and y?

Answer 1

Zn + H2O --- X+ Y

equation - Zn + H2O ---- ZnO + H2

So, X = ZnO

Y = H2

This is Displacement reaction.

DISPLACEMENT REACTION: the reaction in which high reactive metal displace the less reactive metal is called displacement reaction.

Other example - CuSO4 + Fe --- FeSO4 + Cu

In this reaction Fe displace the Cu because Fe is high reactive metal then the Cu.
