A container contains water at 100 kPa. The specific volume of the water inside the container is 1.00 m3/kg. What is the quality (x) of the water in the container, as a percentage and what is the phase of the water in the container?

1- Explain the qualitative differences between the Gibbs free energy and the chemical potential.

2- Explain what is wrong with the following statement: If two (or three) phases of a pure material have the same chemical potential, temperature, and pressure, then the equilibrium state of the system will allow a phase transition between the two (or three) phases.

3- Explain qualitatively the differences between Raoult's law and Henry's law, including the composition range in which they are valid.

I'm writing a report about producing vinyl acetate by reacting ethylene, acetic acid and oxygen to produce vinyl acetate and water.

I want to write about the hazards of the chemical used but not for each one, only the major hazards such as toxicity and flammability, help me

6. a.) Explain the difference between transmittance, absorbance, and molar absorptivity. Which one is proportional to concentration?

6. b.) What is gained by analyzing a larger number of replicates of a sample? What are the practical limitations on minimizing the standard deviation?

6. c.) What are the necessary properties of the sample holder in spectroscopy? What type of cell can be used in the visible range? What type of sample cell should be used in the ultra-violet region of the spectrum?

An engineer is designing a total hip implant. She intends to make the femoral stem out of titanium because it forms a good interface with bone. However, since titanium does not have optimum wear properties she intends to make the ball component out of stainless steel and attach it to the stem using a press fit. Should she be worried about corrosion? If so, what types of corrosion could take place?

A triple-effect evaporator is a process that removes pure water from a salt water feed. The process consists of three units connected in series. The feed to the process contains 3.43 wt % NaCl in water. In the first effect, sufficient water is evaporated to concentrate the solution to 3.89 wt % NaCl. The second effect concentrates the solution further to 4.22 wt %, and the brine discharged from the process contains 5.02 wt % NaCl. a. Draw a diagram of the process, then do a degrees of freedom analysis on each effect and on the entire process to determine which of these choices of system are appropriate starting point(s) for the calculation. b. Determine the total mass of pure water provided by the process per 100 kg of feed. c. Solve for the flow rates of all streams based on 100 kg feed.

Two circular plates each of radius R are separated by a distance of b. The space between the plates is filled with a fluid. The upper plate moves downward at a constant rate V resulting in fluid being squeezed out between the plates. Determine the mass flow rate and maximum velocity under the following conditions: a) The exit velocity is uniform; b). The exit velocity is parabolic.

The total capital investment for a conventional chemical plant is $1,500,000 and the plant

produces 3 million kg of product annually. The selling price of the product is $0.82/kg.

Working capital amounts to 15% of the total capital investment. The investment is from

company funds and no interest is charged. Delivered raw materials costs for the product

are $0.09/kg; Labor, $0.08/kg; utilities, $0.05/kg and packaging, $0.008/kg. Distribution

costs are 5% of the total product cost. Estimate a) the manufacturing cost per kg of

product; (b) total product cost per year; (c) Profit per kg of product before taxes and (d)

profit per kg of product after income taxes at 35% of gross profit.
