Question

which of the following undergo chemical reactions describe the reactions and write the equation
1 ) iron and copper sulphate
2 ) copper and ferrous sulphate
3 ) magnesium and zinc sulphate
4 ) zinc and magnesium sulphate

Answer 1

Answer:

3. answer because the magnesium are bond with metal elements are proper very possible.

Explanation:

it is very difficult possible that the soluble material provide them.

Answer 2

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

and Fe is possible.
