ConsOxidation-reduction reactions (often called "redox"for short) are reactions that ivolve the transfer ofelectrons from one species to another. Oxidationstates, or oxidation numbers, allow chemists tokeep track of these electron transfers. In general,one element will lose electrons (oxidation), with theresult that it will increase in oxidation number, andPart AWhich element is oxidized in this reaction?2CuO + C→2Cu + CO2another element will gain electrons (reduction),thereby decreasing in oxidation number.Enter the chemical symbol of the element.> View Available Hint(s)An oxidizing agent is an element or compound in aredox reaction that oxidizes another species anditself gets reduced and is therefore the electronacceptor in the reaction.is oxidizedA reducing agent is an element or compound in aredox reaction that reduces another species anditself gets oxidized and is therefore the electrondonor in the reaction.SubmitAs a summary, keep in mind the following:Part B Complete previous part(s)• Oxidation means an increase inoxidation state and a loss ofelectrons and involves a reducingagent.• Reduction means a decrease inoxidation state and a gain ofelectrons and involves an oxidizingagent.Part CWhich element is reduced in this reaction?2KMNO4 + 3Na2SO3 + H2O→2MNO2+3Na2 SO4 + 2KOHEnter the chemical symbol of the element.P Pearsoner
