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

One of the few industrial-scale processes that produce organic compounds electrochemically is used by the Monsanto Company to produce1,4-dicyanobutane. The reduction reaction is 2CH2CHCH+2H++2eNC(CH2)4CN The NC(CH2)4CN is then chemically reduced using hydrogen gas to H2N(CH2)6NH2, which is used in the production of nylon. What current must be used to produce 150.kg NC(CH2)4CN per hour?
When magnesium metal is added to a beaker of HCl(aq), a gas is produced. Knowing that magnesium is oxidized and that hydrogen is reduced, write the balanced equation for the reaction. How many electrons are transferred in the balanced equation? What quantity of useful work can be obtained when Mg is added directly to the beaker of HCl? How can you harness this reaction to do useful work?

In the late eighteenth century Priestley prepared ammonia by reacting HNO3(g) with hydrogen gas. The thermodynamic equation for the reaction is HNO3(g)+4H2(g)NH3(g)+3H2O(g)H=637kJ (a) Calculate H when one mole of hydrogen gas reacts.

The mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).
Atomic masses can be determined by electrolysis. In one hour, a current of 0.600 A deposits 2.42 g of a certain metal, M, which is present in solution as M+ ions. What is the atomic mass of the metal?
