Answer» Solution :1.SinceZn displacesCufrom`CuSO_(4)`solution . It ismorereactivethan Cu. (ii)SinceCudisplacesAgfrom`AG NO_(3) `solution , it is morereactivethanAg. 3. SinceznDisplaces Fe from`FeSO_(4) `SOLUTIONIT is morereactivethan Fe. (IV )SinceFedisplaces Cufrom`CuSO_(4)`solutionit ismorereacitvethanCuu. TheDecreasingorderof reactivityof themetalsis: `ZngtFe gtCu GT Ag `
