When balancing reactions in Chapter 3, we did not mention that reactions must be charge balanced as well as mass balanced. What do charge balanced and mass balanced mean? How are redox reactions charge balanced? Explain why we must have the same number of electrons in both half reactions, and write down your answer.
The product from the trans alkylation reactor is returned to the benzene column. Sketch a block flow diagram of the process.
A 0.1025-g sample of copper metal is dissolved in 35 mL of concentrated HNO3 to form Cu2 ions and then water is added to make a total volume of 200.0 mL
Describe two potential options for improving the blood compatibility of biomaterials, discuss their potential for ultimately improving blood compatibility and describe any engineering challenges to implementing these to practice.
Two equilibrium stages at 25C are used as shown in the following diagram. If 300 kg H2O/h is fed to each extraction unit, what fraction of the acetone in the feed solution would be removed and what would be the composition of the combined extract?
Additional data: Assume for simplicity that the ideal-gas heat capacities are constant: n-hexane = 176 J/mol K; n-octane = 247 J/mol K.
Important information about Vapor pressure, At the top of Long's Peak in the Rocky Mountains (a) what is the vapor pressure if boiling a container of eggs (without a lid) occurs
U-235 undergoes many different fission reactions. For one such reaction, when U-235 is struck with a neutron, Ce-144 and Sr-90 are produced along with some neutrons and electrons.
The line is commercial steel pipe, 25 mm internal diameter, length 120 m. The properties of the fluid are: viscosity 0.99 mNm-2 s, density 998 kg/m3. Calculate the total pressure drop due to friction when the flow rate is 3500 kg/h
Derive an equation for the latent heat of fusion that is a function of the radius of the particle. Using this equation, for a copper particle that has a radius of 2.5 nm, find the ratio of the latent heat of fusion of the particle to the laten..
The geometry and dimensions for a section of the blood vessel are shown on the right. Based on the Poiseuille's law the viscous resistance against blood flow through this section is determined to be 0.0002 mmHg•s/ml. If the diameter of the vessel ..
The full-load slip is 4%. Determine the percentage reduction in the applied voltage (i.e., the percentage tap on the autotransformer).
