One step in the isolation of pure rhodium metal (Rh) is the precipitation of rhodium(III) hydroxide from a solution containing rhodium(III) sulfate according to the following balanced chemical equation: Rh2(SO4)3(aq) + 6NaOH(aq) → 2Rh(OH)3(s) + 3Na2SO4(aq) If 3.10 g of rhodium(III) sulfate reacts with excess sodium hydroxide, what mass of rhodium(III) hydroxide may be produced?

Pure copper may be produced by the reaction of copper(I) sulfide with oxygen gas as follows: Cu2S(s) + O2(g) → 2Cu(s) + SO2(g) If the reaction of 0.760 kg of copper(I) sulfide with excess oxygen produces 0.310 kg of copper metal, what is the percent yield?

NOTE THAT QUESTIONS 18 and 20 ARE WORTH 5 POINTS EACH For items 18 – 21, imagine that you have been hired by a company with five offices in the United States. The company has offered you the option to move to whichever city you prefer. All cities offer the same opportunities for advancement within the firm. You remember Professor Soster’s class and decide that, since this is a high effort decision, you will figure out what each of these cities has to offer with respect to location, weather, recreational opportunities, ease of meeting others, and cost of living. Furthermore, you know that some of these attributes are more important to you than other ones. As such, you draw the following table: Attribute Importance Weight Office Locations Houston San Diego Pittsburgh Charlotte Boston Location 1 5 10 6 10 6 10 Weather 2 4 8 10 3 7 6 Recreational Opportunities 3 3 6 6 10 10 10 Ease of Meeting Others 4 2 4 10 10 10 6 Cost of Living 5 1 2 6 8 10 9
