Prelab GALVANIC CELLS: THE NERNST EQUATION Cl-1 + MnO4-1  Mn+2 + Cl2 1. Balance the equation using the ion-electron (half-cell) method. Assume acidic solution. 2. Calculate the Eocell . 3. Calculate Ecell when Mn+2 and Cl-1 are each 1.0 M, MnO4-1 is 1.0 x 10-4 M, Cl2 is at 1 atm pressure, and the pH is 3.00. 4. Calculate the equilibrium constant, Keq, for the reaction.

Question

1) A 1.0 mL aliquot (sample) is taken from a 1.0L solution. Which of the following is/are true when comparing the 1.0 mL solution to the 1.0L solution? Choose all that are true.

-The molarity of the 1.0 mL solution is less than the molarity of the 1.0L solution

-The molarity of each is the same

-The number of moles of solute in each solution is the same

-The number of moles of solute in the 1.0mL solution is less than the number of moles of solute in the 1.0 L solution

2) 5.00 mL is withdrawn from a 1.00L solution of NaCl and diluted to 100.00 mL. If the concentration of the NaCl in the 100.00 mL solution is 0.033, what is the concentration of NaCl in the original 1.00 L solution?

3) What is used as a blank (reference/zero absorbance) for the analysis of the samples in the spectrophotometer?

-Deioniozed water

- Nothing-air

-Acetylsalicylic acid standard solution

- Iron(III) chloride solution

4) The acetylsalycylic acid - iron (III) complex appears violet in color. What color of light is used to measure the absorbance of the solution?

- red

- orange

- green

- blue

- violet

5) A calibration curve for absorbance versus the concentration of the chemical indicator crystal violet is found to have a slope of 48. If a sample of unknown concentration has an absorbance of 1.38, what is the concentration in the unknown sample?

1. Create a network diagram and project schedule (illustrated in a Gantt chart) from the following set of tasks. Use the task number, duration, and dependencies of each task given and construct a schedule so that the project is completed in the least number of days possible. Include a management reserve of approximately 10%.

2. Draw the Network Diagram and calculate the early and late schedules

3. What tasks, in order, are on the critical path?

4. Draw the Schedule as a Gantt Chart?

5. What does the graphical representation of the WBS look like for the project?  

Note: only the terminal graph nodes are shown in the tasks above; construct logical section titles where needed!

1. An insurance company is planning to launch three life insurance policies namely: Standards (s), Preferred (p) and Ultra- Preferred (u). The Manager presents the following information with four scenarios of selling prices and the future profits for each product under the four scenarios:

What would be the managers decisions based on

1. Mamimin criterion selling price of K5
2. Maximax Criterion selling price of k2

Minimax regret criterion

2. The probabilities with which we choose one of three target shooters are 0.2 for Angela, 0.5 for Brunhilde, and 0.3 for Chelsea. The probabilities of each hitting a target from one shot are 0.3 for Angela, 0.4 for Brunhilde, and 0.1 for Chelsea.

(a) The chosen shooter fires one shot and misses the target. Find the probability that we have chosen Angela.

(b) Are the events that Angela was chosen and the target was missed positively related, negatively related, or independent? Justify your answer.

(c) Suppose Angela and Brunhilde each fired one shot at the target. If one bullet is found in the target, find the probability that it came from Brunhilde’s gun. Assume that the two shooters fire at the target independently.

From Gross Domestic Product (GDP), we subtract the depreciation on domestic capital
stock, regardless who owns the capital.
$183 million – $7.2 million – $0.3 million = $175.50
Depreciation on Domestic Capital Stock Owned by Citizens 7.2
epreciation on Domest c Capi al S ock O ned by Foreigners 0.3
epreciat on on Foreign Capital Stock Owned by Citizens 0.8
The depreciation on foreign capital stock is not relevant.
Take heed: An exam problem may give a single depreciation figure. Unless the exam
problem specifies the capital base, the depreciation may be applied with no adjustment.

Question 1.4: GNP
What is Gross National Product (GNP) in 20X8?

1. Estimate the unlevered equity beta for Southwest Airlines. You may assume a 38% tax rate in your calculations.

2. Based on your estimate of Southwest Airlines’ unlevered equity beta, relever the beta to get an estimate of the firm’s levered beta.

3. The airline industry was obviously in a very unique position at the end of 2006. Are there any special concerns that you have regarding the estimation of the cost of equity for Southwest Airlines using the procedure described here?
