Answer:

Hello the required Image related to your question is missing attached below is the missing Image

answer :

a) Ni²⁺(aq) + 2e⁻ ⇒ Ni(s)

b) Fe(s)  ⇒ Fe²⁺(aq) + 2e⁻

c)  Fe (s)

d) Ni ( s )

e)  Fe²⁺(aq)  and  SO⁻²₄ (aq)

f)  Ni²⁺(aq) and  SO⁻²₄(aq)

Explanation:

a) Balanced equation for the half-reaction at the cathode of the cell

Ni²⁺(aq) + 2e⁻ ⇒ Ni(s)

b) Balanced equation for half reaction at the anode of the cell

Fe(s)  ⇒ Fe²⁺(aq) + 2e⁻

c) E1 is made of  Fe (s)

d) E2 is made of Ni ( s )

e) chemical species in solution S1 = Fe²⁺(aq)  and  SO⁻²₄ (aq)

f) Chemical species in solution S2 = Ni²⁺(aq) and  SO⁻²₄(aq)
