In paper chromtography, what is the nature of the attractions between the stationary phase (cellulose) and the moving phase (hydrochloric acid/water/acetone) and the species ( Zn2+, Co2+, Cu2+, Cd2+ , Fe3+, and Ni2+ in two unknown solutions) being separated, in particular what affects the Rf values and how?
Note: Filter paper (Whatman #1) serves as the stationary phase, and the mobile phase consists of a mixture of acetone and 6 M hydrochloric acid. A single spot of the mixture to be analyzed is applied near one edge of a sheet of filter paper. A spot of solution containing each of the cations that might be in the unknown mixture is also placed near the edge of the same sheet for comparison. The treated strip is then placed in a covered jar or beaker (which acts as a developing chamber) containing a shallow layer of the solvent mixture (see Figure 3). Since filter paper is very permeable to the solvent, the solvent begins to rise up the strip by capillary action. The various spots on the developed chromatogram will be highlighted by treatment with several chemical reagents to enhance their color. The reagents to be used are ammonia, dimethylglyoxime (DMG), and 8–hydroxyquinoline (oxine).

10.1Document for Analysis: Poor Persuasive Request Inviting Speaker to Discuss Seven Cardinal Sins in Food Service
(L.O. 1–3)
The following letter from a program chair strives to persuade a well-known chef to make a presentation before a local restaurant association. But the letter is not very persuasive. How could this message be more persuasive? What reader benefits could it offer? What arguments could be made to overcome resistance? How should a persuasive message conclude?
Your Task Analyze the following invitation and list its weaknesses, and write a revision.
Current date
Ms. Danielle Watkins
The Beverly Hills Hotel
9641 Sunset Boulevard
Beverly Hills, CA 90210
Dear Ms. Watkins:
We know you are a very busy hospitality professional as chef at the Beverly Hills Hotel, but we would like you to make a presentation to the San Francisco chapter of the National Restaurant Association. I was asked to write you since I am program chair.
I heard that you made a really good presentation at your local chapter in Los Angeles recently. I think you gave a talk called “Avoiding the Seven Cardinal Sins in Food Service” or something like that. Whatever it was, I'm sure we would like to hear the same or a similar presentation. All restaurant operators are interested in doing what we can to avoid potential problems involving discrimination, safety at work, how we hire people, etc. As you well know, operating a fast-paced restaurant is frustrating—even on a good day. We are all in a gigantic rush from opening the door early in the morning to shutting it again after the last customer has gone. It's a rat race and easy to fall into the trap with food service faults that push a big operation into trouble.
Enclosed please find a list of questions that our members listed. We would like you to talk in the neighborhood of 45 minutes. Our June 10 meeting will be in the Oak Room of the Westin St. Francis Hotel in San Francisco and dinner begins at 7 p.m.
How can we get you to come to San Francisco? We can only offer you an honorarium of $200, but we would pay for any travel expenses. You can expect a large crowd of restaurateurs who are known for hooting and hollering when they hear good stuff! As you can see, we are a rather informal group. Hope you can join us!
Sincerely,
In: Operations Management

Assume that OfficeMart places orders more frequently, but everything else remains the same. On your worksheet increase the number of orders from 4 to 8. (Prior to completing this requirement, change all worksheet figures back to their original amounts.)

(a) What is the customer margin under activity-based costing when the number of orders increases to 8? (Enter a loss as a negative amount.)
(b) What is the product margin under the traditional costing system when the number of orders increases to 8? (Enter a loss as a negative amount.)
(c) Which of the following statements are true? (You may select more than one answer. Single click the box with the question mark to produce a check mark for a correct answer and double click the box with the question mark to empty the box for a wrong answer.

Physical Units Method
Alomar Company manufactures four products from a joint production process: barlon, selene, plicene, and corsol. The joint costs for one batch are as follows:
| Direct materials | $64,581 |
| Direct labor | 36,854 |
| Overhead | 24,940 |
At the split-off point, a batch yields 1,315 barlon, 3,024 selene, 3,549 plicene, and 5,258 corsol. All products are sold at the split-off point: barlon sells for $16 per unit, selene sells for $19 per unit, plicene sells for $25 per unit, and corsol sells for $32 per unit.
Required:
1. Allocate the joint costs using the physical units method. If required, round your percentage allocation to four decimal places and round allocated costs to the nearest dollar. Note: The total of the allocated cost does not equal to the one provided in the question data due to rounding error.
| Allocated Joint Cost | ||
| Barlon | $fill in the blank 1 | |
| Selene | fill in the blank 2 | |
| Plicene | fill in the blank 3 | |
| Corsol | fill in the blank 4 | |
| Total | $fill in the blank 5 |
2. Suppose that the products are weighted as shown below:
| Barlon | 1.1 |
| Selene | 2.1 |
| Plicene | 1.7 |
| Corsol | 2.5 |
Allocate the joint costs using the weighted average method. If required, round your percentage allocation to four decimal places and round allocated costs to the nearest dollar.
