Question

Refer to the activity series chart and determine which of the following displacement reactions can occur. A. 2Ag(s) + Zn(NO3)2(aq) → 2AgNO3(aq) + Zn(s) B. 2Cu(NO3)2(aq) + 2Ag(s) → 2AgNO3(aq) + Cu(s) C. CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s) D. 3MgSO4(aq) + 2Al(s) → Al2(SO4)3(aq) + 3Mg(s)

Answer 1

Answer:

D , C ,B are correct

Explanation:

D)3 Mgso4(aq)+2Al(s)=Al2(so4)3(aq) +3Mg(s) C》Cuso4(aq) +fe(s) = feso4(aq) +cu(s)
