10 45 3 8

2 42

Doaktown Products manufactures fishing equipment for recreational uses. The Miramichi plant produces the company’s two versions of a special reel used for river fishing. The two models are the M-008, a basic reel, and the M-123, a new and improved version. Cost accountants at company headquarters have prepared costs for the two reels for the most recent period. The plant manager is concerned. The cost report does not coincide with her intuition about the relative costs of the two models. She has asked you to review the cost accounting and help her prepare a response to headquarters.

Manufacturing overhead is currently assigned to products based on their direct labor costs. For the most recent month, manufacturing overhead was $326,400. During that time, the company produced 14,400 units of the M-008 and 2,400 units of the M-123. The direct costs of production were as follows:

Management determined that overhead costs are caused by three cost drivers. These drivers and their costs for last year were as follows:

Required:

a. How much overhead will be assigned to each product if these three cost drivers are used to allocate overhead? What is the total cost per unit produced for each product? (Round your intermediate calculations and final answers to 2 decimal places.)

b. How much of the overhead will be assigned to each product if direct labor cost is used to allocate overhead? What is the total cost per unit produced for each product? (Round "Total unit cost" to 2 decimal places.)

Introduction

The decomposition of hydrogen peroxide in aqueous solution proceeds very slowly. A bottle of 3% hydrogen peroxide sitting on a grocery store shelf is stable for a long period of time. The decomposition takes place according to the reaction below. 2 H2O2(aq) → 2 H2O + O2(g) A number of catalysts can be used to speed up this reaction, including potassium iodide, manganese (IV) oxide, and catalase (an enzyme). If you conduct the catalyzed decomposition of hydrogen peroxide in a closed vessel, you will be able to determine the reaction rate as a function of the pressure increase in the vessel that is caused by the production of oxygen gas. If you vary the initial molar concentration of the H2O2 solution, the rate law for the reaction can also be determined. Finally, by conducting the reaction at different temperatures, the activation energy, Ea, can be calculated.

Procedure

1. Obtain and wear goggles. 2. Connect a Gas Pressure Sensor to a computer interface or handheld. Connect the interface to the computer using the proper cable. 3. Place containers with ~15 mL of 3% H2O2, ~10 mL of 0.5 M KI, and ~50 mL of distilled water in a cold water bath that will chill the three liquids to a temperature that will be very close to 10 °C cooler than room temperature. You will use these cold liquids in your 4th trial run of the reaction. 4. Start the data-collection application. Set up the time-based mode to collect pressure readings every several seconds for five minutes. 5. Set up the experiment apparatus: a. Measure out 45 mL of distilled water into a 125 mL Erlenmeyer flask. b. Measure out 10 mL of 3% H2O2 into the flask. Note: Assuming a 3.0% concentration and a density of 1.00 g/mL, the concentration of H2O2 is 0.88 M. CHEM1112 General Chemistry II Laboratory Spring 20163 Decomposition of Hydrogen Peroxide. c. Use a temperature probe or thermometer to measure the temperature of the mixture in the flask, and record this value in your data table. d. Carefully place a magnetic stirring bar into the flask. e. Place a magnetic stirrer on the base of a ring stand. Use a utility clamp to fasten the flask to the ring stand as shown in Figure 1. f. Position the flask at the center of the magnetic stirrer. Test the stirrer speed. Select a moderately slow stirring speed that you will use throughout this experiment, and note the position of the control knob. g. Use the plastic tubing with two Luer-lock connectors to connect the two-hole rubber stopper assembly to the Gas Pressure Sensor, as shown in Figure 1. About one-half turn of the fittings will secure the tubing tightly. The valve connected to the stopper should stay closed during this experiment. h. Measure out 5 mL of 0.5 M KI solution into a 10-mL graduated cylinder. Assume that it is at the same temperature as the water and H2O2 mixture. 6. Prepare to start data collection. a. Transfer the 5 mL of KI solution into the flask. b. Tightly seal the flask with the two-hole stopper connected to the Gas Pressure Sensor. c. Ensure that the flask is properly positioned. Turn the stirrer on to the predetermined setting. 7. Start the data collection. Note: If the pressure exceeds 130 kPa, the pressure inside the flask will be too great and the rubber stopper is likely to pop off. Carefully remove the stopper from the flask if the pressure exceeds 130 kPa. 8. When the data collection is complete, carefully remove the stopper from the flask to relieve the pressure. Dispose of the contents of the flask as directed. 9. Examine the pressure vs. time graph. Find the steepest 20-second segment, and calculate the best-fit linear equation for this segment. Write down the slope of the line, m, as the initial rate of the reaction, in kPa/s. 10. Rinse and clean the flask for the next run. 11. Repeat the necessary steps for Runs 2–4. Use the volumes of H2O2, KI, and distilled water shown in the chart below. For Run 4, remember to use the liquids in the cold water bath. Measure and record the temperature of the water bath. Ideally, the CHEM1112 General Chemistry II Laboratory Spring 20164 Decomposition of Hydrogen Peroxide. temperature of the liquids in Run 4 should be very close to 10 °C cooler than the temperature of Runs 1–3.

A.

write a program the computes n^x and store the result into y

You can use y = Math.pow( Mantissa, exponent)

Requirements:
Besides main() your program must have one method with two parameters, one double and one int

n and x are positive numbers read from the keyboard
if the user makes an entry that does not meet this criteria, the user must be given to opportunity retry the entry

the user must be able to quit prior to entering values for n and x

Your method must compute y and return the result to its caller; the caller will print the result

After printing the result, the user must be queried again if there are other values to compute; if the answer is no exit the program, but if the user replies yes, then repeat the computation

B.
Write a Java program that takes an integer array parameter and returns the sum of integers contained within the array.

C.
Correct code to output the folowing:
0 2 4 6 8 10 12 14 16 18

int[] numbers = new int[10];

for(int i=0; i < numbers.length; ++i)

        numbers[i] = i * 2;

for(int i=0; i < numbers.length; i++)

        System.out.print(numbers[++i] + " ");

System.out.println();
