Use the activity series to predict whether each of the following reactions will occur spontaneously or not.

4) Use the activity series to predict whether each of the following reactions will occur spontaneously or not: a. Cu(s) + 2H+(aq)-→ Cu2+(aq) + H2(g) b. Ni2+(aq) + Fe(s)→ Fe2+(aq) + Ni(s) c. 2Ag(s) + Cu2t(aq)- → 2Ag+(aq) + Cu(s) d. 3Ni2+(aq) + 2Cr(s)--→ 3Ni(s) + 2Cr3+(aq) e. Zn(s) Cu2 (a) Zn2 (aq) Cues) f. Pb2+(aq) + Zn(s)-→ Pb(s) + Zn2+(aq) 5) In a galvanic cell, one half-cell consists of Ni metal in a Ni(NO3)2 and the other half-cell consists of iron metal in Fe(NO3)2 solution. Indicate each of the following: a. the anode b. the cathode c. the half-reaction at the anode d. the half-reaction at the cathode e. the overall reaction plus the standard e.m.f. of the cell f. the cell notation
