Question

Which substance is the oxidizing agent in this reaction? feo+co→fe+co2 express your answer as a chemical formula?

Answer 1

In the equation given above, the oxidizing agent is FeO.
An oxidizing agent in a chemical reaction is defined as that substance, which has the capacity to oxidize other substances by gaining electrons from them. In a chemical reaction, an oxidizing agent is usually reduced by gaining electrons.
In the chemical equation given above, iron ll oxide oxidizes carbon monoxide to carbon dioxide. 

Answer 2

In the reaction; FeO + CO → Fe + CO2, FeO is the oxidizing agent.

Further Explanation

Redox reactions

• Redox reactions are types of reactions that involve both oxidation and reduction occurring simultaneously.  In these reactions one of the reactant undergoes oxidation while another undergoes reduction.

Oxidation

• Oxidation involves the loss of electrons by an element. When an element or an ion undergoes oxidation, it looses electrons.
• For example; in the above reaction carbon monoxide undergoes oxidation.
• C²⁺ → C⁴⁺ + 2e

Reduction

• Reduction refers to the gain of electrons by an element. Therefore, when an element or an ion undergoes reduction it gains electrons.

• For example; in the above reaction iron (ii) oxide undergoes reduction.
• Fe²⁺ + 2e → Fe

Oxidizing agent

• An oxidizing agent in a chemical reaction is defined as that substance, which has the capacity to oxidize other substances by gaining electrons from them. In a chemical reaction, an oxidizing agent is usually reduced by gaining electrons.
• In the chemical equation given above, iron ll oxide oxidizes carbon monoxide to carbon dioxide. 

Reducing agent

• A reducing agent in a chemical reaction is defined as that substance, which has the capacity to reduce other substances by losing electrons from them.
• In a chemical reaction, a reducing agent is usually oxidized by loosing electrons.
• In the chemical equation given above, carbon monoxide reduces iron (ii) oxide to iron metal.
