(a) Interpretation: The unbalanced half reactions for the following reaction should be written along with the species which is reduced and oxidized; and oxidizing agent and reducing agent should be determined. As 2 O 3 (s) + MnO 4 − ( aq) → H 3 AsO 4 (aq)+Mn 2 + (aq) Concept introduction: The chemical reaction in which both oxidation and reduction process takes place is known as redox reaction . In this reaction, transfer of electrons takes place among the elements. A half reaction is a component of redox reaction which is either oxidation half reaction or reduction half reaction. Oxidation is the process in which either loss of electrons, oxidation number increases, or loss of hydrogen atoms takes place. An element is oxidized, when oxidation number increases. Reduction is the process in which either gain of electrons, oxidation number decreases, or gain of hydrogen atoms takes place. An element is reduced, when oxidation number decreases.

Hi, I need help on my practice final, If you could offer strategies and dumb it down for me with an explanation on how to solve that would be amazing and beneficial.
