Question

which of the following can undergo reaction​

Answer 1

Answer:

The Reactivity series is an arrangement of metals in the order of decreasing reactivities. We can infer that a more reactive metal displaces a less reactive metal from a solution of its salt.

K>Na>Ca>Mg>Al>Zn>Fe>Pb>H>Cu>Hg>Ag>Au

From the reactivity series, it is clear that Fe is more reactive than Cu and can replace Cu. But in the case of Mg and Zn, we find that they are more reactive than Fe and same in the case of Mg and Pb where Mg is more reactive than Pb.

Hence, the reaction of CuSO

4

and Fe is possible.

Answer 2

Answer:

Answer is option D)

Explanation:

beacause in reactivity series the Fe is highly reactive then Cu so, Fe was undergo equation
