Consider the following set of reactions :
(A) Mg + CuO → MgO + Cu
(B) 2 Na + MgO → Na2O + Mg
(C) Zn + CuO → ZnO +Cu
What can you infer from the above set of reactions?
1
Reactivity of Cu is more than Mg but less than Na
2
Reactivity of Cu is greater than Zn
3
Reactivity of Mg is more than Cu but less than Na
4
Reactivity of Mg is more than Na
