Interpretation:
The reactant that is oxidized and the reactant that is reduced in the given reaction are to be identified.
Concept Introduction:
Redox reactions are the reactions in which one of the reactants gets oxidized and the other gets reduced simultaneously. The reactant that oxidizes the other substance is known as oxidizing agent. The oxidizing agent gets reduced in the reaction. The reactant that reduces the other substance is known as reducing agent. The reducing agent gets oxidized in the reaction. An increase in oxidation number of a substance indicates that the substance got oxidized, whereas, a decrease in the oxidation number of a substance indicates that the substance got reduced. The addition of oxygen or the removal of hydrogen is termed as oxidation. The addition of hydrogen or the removal of oxygen is termed as reduction.

- 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?arrow_forwardWhat mass of oxygen is needed for the complete combustion of 3.30×10−3 g of methane? CH4(g)+2O2(g)→CO2(g)+2H2O(g)arrow_forwardWhat is oxidized and what is reduced in the following reaction?2Al(s) + 3Br2(g) → 2AlBr3(s) Al is oxidized and Br2 is reduced. AlBr3 is reduced and Br2 is oxidized. AlBr3 is reduced and Al is oxidized. Al is reduced and Br2 is oxidized. AlBr3 is oxidized and Al is reduced.arrow_forward
- A 550 MW coal-fired power plant burning bituminous coal has an annual capacity factor of 0.75 and a thermal efficiency of 25%. a. How much coal (in tons) does this plant consume in one month? b. What is the annual electrical generation during this period? c. How much CO2 is emitted annually?arrow_forwardAircraft de-icing agents, such as propylene glycol [1,2-propanediol; CH₃CH(OH)CH₂OH; d=1.036 g/mL], are used toremove ice and snow prior to winter flights, but their presence inrunoff depletes O₂ in natural waters. (a) Write a balanced equa-tion for the complete oxidation of propylene glycol by O₂.(b) What is the “theoretical oxygen demand,” in grams of O₂ required per gram of propylene glycol oxidized? (c) What is thetheoretical oxygen demand, in grams of O₂ required per liter ofsolution, of 90.0% by volume aqueous propylene glycol?arrow_forwardComplete and balance the reaction for the complete combustion of the following fuels. You do not need to indicate the physical state of the reactants and products Propane, C3H8 Butyl Alcohol, C4H9OHarrow_forward
- Reaction; CH4 + 2O2→CO2 +2H2O + 806 kJ A) what amount of energy is produced when 250 moles of methane is combusted? B) How many moles of methane will be used to produce 25000 kJ?arrow_forwardA typical passenger vehicle emits about 5,634 L of carbon dioxide per year. Octane (C8H18) is a hydrocarbon found in gasoline. How many kg of octane would need to be oxidized to produce 5,634 L of CO2? Assume the carbon dioxide is at 12.25ºC and 0.815 atm. Give your answer to 3 sig figs! 2 C8H18(l) + 25 O2(g) → 16 CO2(g) + 18 H2O(g)arrow_forwardThe complete combustion of which of the following substances produces carbon dioxide and water?
