A city is considering building a new multi-purpose sports and entertainment complex. The city would spend $306 million immediately to construct the complex. Annual revenue from this complex would be $44 million and annual operations and maintenance costs would be $11 million. The city's MARR is 12.7% compounded annually. Assume the annual revenue and costs will remain the same under these conditions for an infinite amount of time. What is the present worth of the entertainment complex? Enter your answer in millions of dollars.
Explain why gas chromatography usually ramp(increase) the oven temperature during an analysis
The total pressure is 6.80atm . If the Henry's law constant for N2 in water at this temperature is 7.92x10^-5 M/mmHg and the density of the solution is 0.998 g/mL what is the molality of a solution made using the same partial pressure of N2 from t..
The hydrolysis of sucrose to fructose is first order in sucrose with a half-life of 2.3e+03 s at some temperature. 1.What fraction of sucrose, expressed as a percent, would hydrolyze in 2.8 hours
A 10.00mL aliquot of a weak base is titrated with HCL. The equivalence point is reached after 17.21mL of 0.4332 mol/L HCL has been added. The pH is equal to 10.03 after 5.00mL of HCL was added. Determine
The partial pressures of gas B dissolved in liquid A at 298 K are listed in the table below. If the vapor pressure of pure B at this temperature is 9500 Kpa, does this solution obey Raoult's Law
Determine the number of moles of O2 produced by the decomposition of 213 g of NaClO3.
a 4.305-gram sample of a nonelectrolyte is dissolved in 105 grams of water. the solution freezes at -1.23degc.
Using the same sample of gas (P 1= 795 torr , T 1 = 37 C ), we wish to change the pressure to 7950 torr with no accompanying change in volume or amount of gas. What temperature T 1, in Celsius, is needed to reach this pressure
Problem- what is the solubility of AgI in 0.010M KCN solution. How does it compare to the solubility of AGI in water. Ksp of AGI=8.3x10^-17 and Kf of Ag(CN)2=5.3x10^18.
At 10 degrees, Kc = 56.3 for the reaction below. H2 + Cl2 --> HCl
Problem- You need to produce a buffer solution that has a pH of 5.44. You already have a solution that contains 10. mmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this s..
