100mL of 3M NaOH is poured into 100mL of 3M HF. The highest temperature reached is 48.71 degrees Celcius.
3M NaOH inital temp= 25 degrees Celcius
3M HF inital temp= 25 degrees Celcius
a. How many moles of Hf reacted? How many moles of NaOH?)
b. Assuming the specific heat of the mixed solution is 4.18 J/(g*C), and that the density of the mixed solution is 1.00 g/mL, use q = CDT to determine the heat added to the solution.
c. Heat evolved by the reaction is the negative of heat added to the solution. Find heat evolved per mol of HF that reacts.
d. Compare the %deviation of the result of c. to the result of Part 1 for this reaction.
Does the highest temperature reached (48.71) show accurate heats of reaction?

Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. Prompt the user for 12 months of highest and lowest. Write two methods : one to calculate and return the average high and one to calculate and return the average low of the year. These methods MUST be your original code. Your program should output all the values in the array and then output the average high and the average low.
Remember to submit all your .java files, .class files and screenshots of your code and output.

9. An analysis of company performance using DuPont analysis A sheaf of papers in his hand, your friend and colleague, Jason, steps into your office and asked the following. JASON: Do you have 10 or 15 minutes that you can spare? YOU: Sure, I’ve got a meeting in an hour, but I don’t want to start something new and then be interrupted by the meeting, so how can I help? JASON: I’ve been reviewing the company’s financial statements and looking for ways to improve our performance, in general, and the company’s return on equity, or ROE, in particular. Anja, my new team leader, suggested that I start by using a DuPont analysis, and I’d like to run my numbers and conclusions by you to see whether I’ve missed anything. Here are the balance sheet and income statement data that Anja gave me, and here are my notes with my calculations. Could you start by making sure that my numbers are correct? YOU: Give me a minute to look at these financial statements and to remember what I know about the DuPont analysis.
If I remember correctly, the DuPont equation breaks down our ROE into three component ratios: the , the total asset turnover ratio, and the . And, according to my understanding of the DuPont equation and its calculation of ROE, the three ratios provide insights into the company’s , effectiveness in using the company’s assets, and . Now, let’s see your notes with your ratios, and then we can talk about possible strategies that will improve the ratios. I’m going to check the box to the side of your calculated value if your calculation is correct and leave it unchecked if your calculation is incorrect. Cepeus Manufacturing Inc. DuPont Analysis
JASON: OK, it looks like I’ve got a couple of incorrect values, so show me your calculations, and then we can talk strategies for improvement. YOU: I’ve just made rough calculations, so let me complete this table by inputting the components of each ratio and its value: Do not round intermediate calculations and round your final answers up to two decimals. Cepeus Manufacturing Inc. DuPont Analysis
JASON: I see what I did wrong in my computations. Thanks for reviewing these calculations with me. You saved me from a lot of embarrassment! Anja would have been very disappointed in me if I had showed her my original work. So, now let’s switch topics and identify general strategies that could be used to positively affect Cepeus’s ROE. YOU: OK, so given your knowledge of the component ratios used in the DuPont equation, which of the following strategies should improve the company’s ROE? Check all that apply. Decrease the company’s use of debt capital because it will decrease the equity multiplier. Use more debt financing in its capital structure and increase the equity multiplier. Increase the efficiency of its assets so that it generates more sales with each dollar of asset investment and increases the company’s total assets turnover. Use more equity financing in its capital structure, which will increase the equity multiplier. JASON: I think I understand now. Thanks for taking the time to go over this with me, and let me know when I can return the favor. Grade It Now Save & Continue Continue without saving |
