8 0

Answer:

Fe → Fe⁺³ + 3e⁻

Explanation:

The oxidation half reaction for iron is:

Fe → Fe⁺³ + 3e⁻

Other options are incorrect because,

A) 3e⁻ + Fe  →   Fe³⁺

This is incorrect because when three electrons are gained by any atom it will gain negative three charge not positive.

C) 6e⁻ + 2Fe →  2Fe³⁺

This is incorrect because when six electrons are gained by any atom it will gain negative six charge not positive.

d) Fe →  2Fe³⁺ + 6e⁻

Its also incorrect because iron atoms are not balanced on both side of equation.
