Question

the following reaction are observed to occur
a) CuSO4 +Zn ------ FeSO4
b)FeSO4+Cu------- ZnSO4+Fe. c)2AgNO3+Cu -------Cu(NO3)2 +2Ag. Arrange Cu,Fe,Ag and Zn in order of thier reactivity​

Answer 1

Answer:

from most to least reactive- Zn, Fe, Cu, Ag

Answer 2

Answer:

We know that the more reactive metal displaces the less reactive one. Here in the reaction Fe Displaces Cu so, Fe is more reactive. In the second reaction, Cu displaces Ag so, Cu is more reactive.

So, the increasing order is Ag < Cu < Fe.
