a. Is zirconium metal capable of reducing water to form hydrogen gas at standard conditions?
b. Write a balanced equation for the reduction of water by zirconium.
c. Calculate e°, G°, and K for the reduction of water by zirconium metal.
d. The reduction of water by zirconium occurred during the accidents at Three Mile Island in 1979.
The hydrogen produced was successfully vented and no chemical explosion occurred. If 1.00 103 kg of Zr reacts, what mass of H2 is produced? What volume of H2 at 1.0 atm and 1000.°C is produced?
Assuming that there are no other significant side reactions, calculate masses of alcohol and ether produced, per 1000 kg of allyl chloride fed to the reactor.
Explain the term "Selectivity" and "Yield".Selectivity is defined as the ratio of moles of desired product to moles of undesired product.Yield is defined as the ratio of moles of product formed to moles of reactant eitherfed or consumed and What a..
A 60-Hz, 440-V, three-phase system feeds two balanced wye-connected loads in parallel. One load has a per-phase impedance of 8 + j3 Ω and the other 4 - j1 Ω.
Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 g/cm3. How much sodium carbonate was required for complete neutralization of the spill, and how ..
Steam at 500 C and 40 bar passes through two turbines arranged in parallel, and their exit streams are combined into one stream. Turbine 1 has 100% efficiency, while the efficiency of turbine 2 is 75%. Both turbines exhaust at 1 bar. The stream th..
Figure P6.1.39 shows a full adder with the idea of adding Ci to the partial sum S' , which is the same logic process as addition with pencil and paper.
From the magnetic moment of 1.7 μB per Co in metallic Co, predict what Ms will be. Note that a unit cell of Co contains 6 atoms, and has a volume of 6.68×10-2nm3.Ms (in kA/m):
She believes she can extract 1700 kW of work and 220 kW of heat that will be used to boil water at 1 bar. Her process, whose details are yet to be determined, will receive streams A and B as inlet and will have a single outlet stream that will be ..
It has been suggested that carbon dioxide can be recovered from flue by using a membrane process. The flue gas has the following composition:
calculate the induced voltage, given that the number of parallel paths is equal to the number of poles for lap windings.
The column will operate at 1.1 bar and ambient temperature. If necessary, the aqueous stream may be recirculated to maintain a suitable wetting rate.
A feed to a column has the composition given in the table below, and is at a pressure of 14 bar and a temperature of 60 °C. Calculate the flow and composition of the liquid and vapor phases. Equilibrium data can be taken from De Priester charts (D..
