Write unbalanced oxidation half-reaction for the following process.

Fe2O3(s)+CO(g)Fe(s)+CO2(g)

Express your answer as a chemical equation. Identify all of the phases in your answer.

Write unbalanced reduction half-reaction for the following process.

Fe2O3(s)+CO(g)Fe(s)+CO2(g)

Express your answer as a chemical equation. Identify all of the phases in your answer.

Solution :-

while writing the oxidation and reduction equations we use the oxidation states of the element to determine if its undergoing oxidation or reduction.

Unbalanced equation

Mn3+(aq)MnO2(s)+Mn2+(aq)

in this equation Mn is the element which undergoing oxidation and reduction simultaneously

Writing half equations

Mn3+(aq) ----- > MnO2 (s) oxidation

Mn3+ (aq) ----- > Mn2+ (aq) reduction

So the unbalanced oxidation equation is as follows

Mn3+(aq) ----- > MnO2 (s) oxidation

2) unbalanced oxidation equation for the

Fe2O3(s)+CO(g)Fe(s)+CO2(g)

here CO is undergoing oxidation so the equation is as follows

Unbalanced oxidation equation Is as follows

CO(g) ------ > CO2(g) oxidation

3) unbalanced reduction equation is as follows

Fe is reduced in this equation

Fe2O3(s) --------- > Fe(s) reduction.
