Be sure to answer all parts. For the complete redox reactions given here, write the half-reactions and identify the oxidizing and reducing agents. Make sure your answer has the simplest coefficients. Part 1 out of 4 (a) 4Fe + 3O2 → 2Fe2O3 Select the oxidizing agent:

Answer : is the oxidizing agent and Fe is the reducing agent.

Explanation :

Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.

Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.

The balanced redox reaction is :

The half oxidation-reduction reactions are:

Oxidation reaction :

Reduction reaction :

In order to balance the electrons, we multiply the oxidation reaction by 4 and reduction reaction by 3 then added both equation, we get the balanced redox reaction.

Oxidation reaction :

Reduction reaction :

In this reaction, is the reducing agent that loses an electron to another chemical species in a redox chemical reaction and itself gets oxidized and is the oxidizing agent that gain an electron to another chemical species in a redox chemical reaction and itself gets reduced.

Thus, is the oxidizing agent and Fe is the reducing agent.
