A. For a pure component, a cubic equation of state has three molar volume roots. However, for a binary mixture, a cubic equation of state will have four molar volume roots, since the number of components has increased by one. B. If one models the vapor-phase of a mixture as an ideal solution, this means that the mixture fugacity coefficient of component i will be equal to the pure component fugacity of component i at the mixture temperature and pressure. C. The van der Waals one-fluid mixing rule requires that the mixture parameters are the same in both the liquid and vapor phases. D. In modeling vapor-liquid equilibrium using the gamma-phi approach, you can disregard the effect of Poynting correction factor. E. None of the above are true.
Mr. Walker built a new home on a two-acre lot. The house, drive, and walks contain 3,200 square feet. He has an area for plants in front of the house 5 feet wide and 62 feet long to which 4 inches of topsoil were added. In front of the other plants in the area, he set out annuals 8 inches apart. The annuals come in trays of 12 four-packs. He laid 150 feet by 110 feet of sod in the front lawn. The remainder of the lawn was seeded with 2.2 pounds of grass seed per 1,000 square feet, and he applied 4.5 pounds of nitrogen per 1,000 square feet using the lawn fertilizer 20-5-10 that comes in 50-pound bags.
a. How many square feet of sod did he lay? b. How many cubic yards of topsoil did he add to the plant area? c. How many trays of annuals did he purchase? d. How many square feet did he seed? e. How many pounds of grass seed did he use? f. How many bags of fertilizer did he purchase?
