Answer:
Anode half reaction equation:
Ni(s)------> Ni^2+(aq) + 2e-
Explanation:
Looking at the values of reduction potential given in the question, Ni2+|Ni half cell has a more negative reduction potential than the Fe3+|Fe2+ half cell. The more negative the reduction potential of a half cell, the more its tendency to act as the anode. Hence based on the half cell reduction potentials presented in the question, Ni2+|Ni is the anode while the other is the cathode.

<em>Answer:</em>
<em>Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.</em>
