Quinine (C20H24N2O2) a white crystalline bitter tasting powder which was originally used as a preventative medication for malaria. It is a weak base with kb=3.3 x 10^-6 M. However, Quinine is now more commonly used in small concentrations in tonic water. Quinine is responsible for the fluorescent properties when tonic water is under ultraviolet light (blacklights). Due to the toxic effects of quinine the United States limits the quinine content to 83 ppm for each 1 liter bottle.
Write a balanced chemical equation of quinine solid dissolving in water including all phases, and indicate which species is an acid, base, conjugate acid and conjugate base.
Calculate the pH of the tonic water.

In an attempt to reduce the extraordinarily long travel times for voyaging to distant stars, some people have suggested traveling at close to the speed of light. Suppose you wish to visit the red giant star Betelgeuse, which is 430 ly away, and that you want your 20,000 kg rocket to move so fast that you age only 24 years during the round trip.
A) How fast, as a fraction of c, must the rocket travel relative to earth?
B) How much energy is needed to accelerate the rocket to this speed?
C) Compare this amount of energy to the total energy E0 used by the United States in the year 2015, which was roughly 1.0×1020 J.

1. Workers in the manufacturing floor are being replaced by robots and other machines. On one hand, this lets companies compete with cheap labor from other countries. On the other hand, automation eliminates many jobs. Are you concerned that automation may increase unemployment or underemployment in the United States and around the world?
2. If a company provides employer-paid child care services to workers with children, should those who don't have children or don't need child care be compensated any other way?
3. What advantages do compensation plans such as profit sharing and employee stock ownership offer an organization? What are the benefits and challenges of flextime, tele-commuting, and job sharing?

In this hypothetical case study, a new rapid test kit nicknamed Alpha is being reviewed. The sensitivity of Alpha is 93.0% (0.93) and the specificity is 96.0% (0.96). Assume that the actual prevalence of the Zika antibody among the United States population of blood donors is 4% (0.04) and that of the hurricane disaster relief volunteers returning from Puerto Rico is 20.0% (0.20).
Construct a separate 2 x 2 table, to calculate the PPV and NPV for a population of 2,500 volunteers who aided in the recent hurricane relief efforts in the Caribbean.
If sensitivity and specificity remain constant, what is the relationship of prevalence to predictive-value positive and predictive-value negative? (Hint: Think if one increases, decreases, or stays the same.)

travel times for voyaging to distant stars, some people have
suggested traveling at close to the speed of light. Suppose you
wish to visit the red giant star Betelgeuse, which is 430 ly l y
away, and that you want your 20,000 kg k g rocket to move so fast
that you age only 38 years during the round trip.
How fast must the rocket travel relative to
earth?
How much energy is needed to accelerate the rocket to
this speed?
How many times larger is this energy than the total
energy used by the United States in the year 2000, which was
roughly 1.0×1020J1.0×1020J?

Roger has a levered cost of equity of 0.12. He is thinking of investing in a project with upfront costs of $8 million, which pays $2 million per year for the next 8 years. He is going to borrow $4 million to offset the startup costs at a rate of 0.05. His tax rate is 0.3. He will repay this loan at the end of the project. What is the NPV of this project, using the FTE method?
