Read the following chemical equation. fe(s) + o2 (g) → fe3+ o2− what most likely happens during this reaction? iron loses three electrons. iron gains three electrons. oxygen loses two electrons. oxygen gains two electrons.

Iron loses three electrons and oxygen gain two electrons.

Explanation:

this reaction represents the formation of rust of Fe.

4Fe + 3O2 → 2Fe2O3

The Fe is oxidized by oxygen and converts from Fe (oxidation number = 0) to Fe3+ (oxidation number = 3+) that  Fe loses 3 electrons.The oxygen is reduced and the oxidation state changed from 0 to 2- that oxygen loses 2 electrons.The other 2 choices are clear to be wrong.

The answer is true for your question.

The answer is 65.3312
