Question

observe the following chemical reactions
Fe + cu so4 → feso4+ cu
zn + fe so4 → znSo4 + fe
the decreasing order of reactivating of metals in the above reaction is
a) zn > fe > cu
b) fe > cu > zn
c) zn > cu > fe
d) cu > fe > zn​

Answer 1

Answer:

Zn>Fe>Cu

Explanation:

• In first chemical reaction Iron(Fe) is more reactive than Copper(Cu) For which it displaces copper from its compound .
• In second chemical reaction Zinc(Zn) is more reactive than Ferrous(Fe) For which it displaces Fe from its compound.
