I don't know if this the right place to ask this but anyway I'm asking.
I'm a 12 year old and this year I learned about displacement reaction. I don't understand how the whole thing works so can anyone please explain to me how it works.

Displacement reaction is just like a power game - the one which is more powerful replaces the less powerful from its compound.Like  Zn  is more reactive metal then Cu so
Zn + CuSO4 ---> ZnSO4 + Cu
but the reverse is not true
