(c) Mg + CusO --}Mgso +Cu

(i) - (a) and (b)
(ii) - (b) and c)
(iii) - (c) and (d)
(iv) - (a) and (d) ​


Please give a correct answer ​

Answer 1

CuSO4 + Fe can undergo a chemical reaction. As iron metal is more reactive than copper metal, iron displaces copper from copper sulphate solution and forms aqueous iron sulphate (FeSO4) and solid copper (Cu). This a single displacement reaction also known as a substitution reaction. The iron can be solid or aqueous but the copper sulphate must be aqueous in order to facilitate the reaction.
