Let’s compare two monoprotic acids: one strong (nitric, HNO3, pKa = -1.60) and one weak (acetic, CH3COOH, pKa = 4.79).

a. [4 points] Sketch an alpha diagram for each of the acids.

b. [6 points] Use your alpha diagram to predict the percentage of undissociated acid for each at the following pH values: 0.1, 3, 4.3, 6, and 13. After estimating the fractions with your diagram, check your values by calculating the exact value.

c. [4 points] Explain the difference in pKa values (and the percentage dissociated in parts a and b) for nitric acid and acetic acid. In your explanation, include and underline the following terms: pH, H+ concentration, strong/weak acid, and Le Chatelier’s Principle.

Butane liquid and vapor coexist at 370.0K and 14.35 bar. The densities of the liquid and vapor phases are 8.128 mol-L^-1 and 0.6313 mol-L^-1, respectively. Use the van der Waals equation, the Redlich-Kwong equation, and the Peng-Robinson equation to calculate these densities. Take alpha = 16.44 bar-L^2-mol^-2 and beta = 0.07245 L-mol^-1 for the Peng-Robinson equation.

My question about the Allowance Method is why do you still estimate a total of the allowance of doubtful accounts when you are going to figure out who will not pay at the end anyway?

A society has 2 goods, A and B, for two people, Larry and Javier. The price of A and B are PA = $4 and PB = $10. Larry’s utility function is UL(A, B) = 40X0.25B0.5 and income is YL = $600. Javier’s utility function is UJ(A, B) = A0.5B0.5 and income is YJ = $2,400. Marginal utilities for Larry and Xavier are:

Larry: MUA = 10A-0.75B0.5 and MUB = 20A0.25B-0.5

Xavier: MUA = 0.5A-0.5B0.50 and MUB = 0.5A0.5B-0.5

1. Find the utility maximizing consumption choices of A and B for Larry and Javier.  Explain your work.
2. Currently in this economy, there are 300 units of good A supplied and 200 units of good B supplied.  Given the consumption demands for A and B above, is this economy in a competitive equilibrium?  If so, explain why.  If not, explain how prices and outputs will adjust to move toward an equilibrium.
3. Draw the situation described in parts a and b in an Edgeworth Box.

what were the root causes to either market failure or government failure or both for India 1991-1997

1.) Chlorofluorocarbons (CFCs) were introduced as refrigerants in the 1930s, replacing other gases that were toxic and corrosive. How do the molecular shape and polarity of CFCs contribute to the many desirable qualities they have as refrigerants? Given that they are such desirable refrigerants, why are they banned? What chemistry is involved? How has their molecular shape and polarity had harmful effects on the atmosphere?

2. Chemically, how does soap work to remove grease? Give some other related examples.

1. Discuss how a pathogen causes an infection. Include definitions for primary pathogen, opportunistic pathogen, infection, disease (caused by a living organism), and various stages of pathogenesis. You can choose a specific organism to describe (like Orthomyxovirus and Influenza) or discuss a generalized infection.

2.

Describe each type of infection in the following list and include the mode of transmission in each scenario. Use terms such as primary, secondary, healthcare-associated, STI, mixed, latent, toxemia, chronic, zoonotic, asymptomatic, local, and systemic to describe the types of infections (more than one term may apply, some may not apply to these conditions)

1) The development of Pneumocystis pneumonia in an AIDS patient
2) Salmonellosis
3) Hantavirus pulmonary syndrome infection acquired while vacationing in a log cabin

1. Interest Rate Parity, Purchasing Power Parity, International Fisher deEffect Separated by more than 3,000 nautical miles and five time zones, money and foreign exchange markets in both London and New York are very efficient. The following information has been collected from the respective areas: Assumptions London New York Spot exchange rate ($/pound) 1.3264 1.3264 One-year Treasury bill rate 1.5% 2.5% Expected inflation rate Unknown 2.0% a. Estimate today's one-year forward exchange rate F between the dollar and the pound using Covered Interest Rate Parity. b. Find approximate expected inflation in London next year. Is it smaller or larger than New York expected inflation? Why? You can do the forecast using PPP or International Fisher Effect. If you use PPP then assume that the Expected exchange rate E(S) is the same as the forward exchange rate F that you found in (a). Then solve for expected inflation in London using PPP formula. If you use International Fisher effect assume that the real interest rates for two countries are the same.

What is involved in collecting requirements for a project? Why is it often difficult to do?

On January 1, 2018, Instaform, Inc., issued 10% bonds with a face amount of $54 million, dated January 1. The bonds mature in 2037 (20 years). The market yield for bonds of similar risk and maturity is 12%. Interest is paid semiannually. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)

Project 2

This project has three components:

Analyse Canada’s nominal and real GDP for last 5 years with the help of a table/bar chart/Graph.

Prepare a one-page analysis on the indicators reflecting economy’s well being.

Does the following statement give you a true picture of the situation: “Real GDP in the United States is higher than real GDP in Canada. Therefore, the standard of living in the United States must be higher than that in Canada.” Why? Why not?
