Question

Based on the oxidation states of the atoms in this reaction, answer the questions. 4Fe(0) + 3O2(0) → 2Fe2(3+)O3(2-) How many electrons does the iron half-reaction lose? How many electrons does the oxygen half-reaction gain? What is the total number of electrons that are moved in this oxidation-reduction reaction?

Answer 1

How many electrons does the iron half-reaction lose?

12

How many electrons does the oxygen half-reaction gain?

12

What is the total number of electrons that are moved in this oxidation-reduction reaction? 12

Step-by-step explanation:

Answer 2

Twelve electrons

Step-by-step explanation:

If we look at the product side, we will notice that iron lost twelve electrons and oxygen gained twelve electrons.

Hence, we have 4Fe^3+ and 2O3^2- showing twelve electrons lost/gained.
