CuSO4 (aq) + Fe(s) = FeSO4(aq) + Cu(s) FeSO4 (aq) + Zn(s) = ZnSO4(aq) + Fe(s)Al2(SO4)3 (aq) +Zn(s) = No reactionArrange above metals in increasing order of their reactivities.

CuSO4 (aq) + Fe(s) = FeSO4(aq) + Cu(s) FeSO4 (aq) + Zn(s) = ZnSO4(aq

1.	CuSO4 (aq) + Fe(s) = FeSO4(aq) + Cu(s) FeSO4 (aq) + Zn(s) = ZnSO4(aq) + Fe(s)Al2(SO4)3 (aq) +Zn(s) = No reactionArrange above metals in increasing order of their reactivities.
Answer» AL ZnFeCuAluminium is the most reactive and copper is the least reactive ACCORDING to the reactivity SERIES of METAL.
