Question

Observe the following chemical reactions
Fe + Cuso
Zn + FeSO, → ZnSO, + Fe
FeSO, + Cu
The decreasing order of reactivity of metals in the above reaction
A. Zn > Fe > Cu
B. Fe > Cu > Zn
C. Zn > Cu > Fe
D. Cu > Fe > Zn​

Answer 1

Answer 2

Answer:

Ans.-A Zn>Fe>Cu

Explanation:

K (highly reactive)

Na

Ca

Mg

Al

Zn

Fe

Pb

H

Cu

Hg

Ag

Au (least reactive)

As above reactivity list zinc come before iron and copper so it is highly reactive than both of these metals and iron comes before copper so it is more reactive than copper and the copper is least reactive

Hope this help
