Question

The half reaction of an oxidation-reduction reaction shows that iron gains electrons. What does this electron gain mean for iron? A. It is neutralized. B. It is oxidized. C. It is reduced. D. It has dissolved. E. It has precipitated.

Answer 1

Answer: is C. It is reduced.

Explanation:

Answer 2

The  electron  gain  for iron means  that it   is reduced  (answer C)

Explanation

 Redox    reaction  is  made up of two halves.

That  is a   reduction  half and a  oxidization  half.

In the   reduction   half   electrons are  gained  which result  to  decrease  in oxidation number.

In  the Oxidization  half   electrons are  lost which result  to  increase  in  oxidation  number.

iron    is therefore   reduced  since  it gains  electrons
