Representation of Single Replacement Reaction by Cartoon DanceThe displacement reaction is a type of REDOX reacn. In these reactions, the more reactive element replaces the less reactive one from it's compound. As for example, more reactive Zn replaces less reactive Cu
from CuSO4 & more reactive non-metal Cl replaces less reactive
non-metal I from KI.
Zn + CuSO4 = ZnSO4 + Cu
Cl2 + 2 KI = 2 KCl + I2
