Five moles of monatomic ideal gas are contained at a pressure of 4 atm and a temperature of 250 K. 35400 J of heat are transferred to the gas. Then, the gas pressure is used to expand a piston, and the expanding gas does 1200 J of work against its surroundings. However, the piston is not perfectly insulated, and 600 J of heat is lost from the gas during the expansion. All processes are reversible. Calculate the final temperature of the gas.

A particular smoke detector contains 1.95 μCi of ²⁴¹Am, with a half-life of 458 years. The isotope is encased in a thin aluminum container. Calculate the mass of ²⁴¹Am in grams in the detector.

Express your answer numerically in grams.

1. (a) What functional groups are present in (i) PET, (ii) Nylon and (iii) adipoyl chloride ?
2. 2. These three functional groups in question 1(a) are part of a larger family of functional groups. What is that larger family ?
   3. C. The larger family of functional groups in question 1(b) typically undergo reactions of a common general mechanistic pathway. The hydrolysis of PETE and the formation of Nylon in this experiment are both examples of this. What is the name of type of mechanism ?
3. 2- Industrially, nylon-6,6 is made by heating a diamine with a dicarboxylic acid. In a laboratory setting, it is difficult to make nylon using this method due to the formation of another product. Provide an equation to show this reaction.
4. 3- Polyesters can be made using the acid catalysed reaction of carboxylic acids and alcohols. Draw the curly arrow mechanism for this reaction by showing how methanoic acid and ethanol react to give ethyl methanoate.

Add a recursive function called isLesser to class IntegerLinkedList to calculate the smallest of the linked list’s data values (same as in Problem 2 but recursive).

A recursion “helper” function is already included in class IntegerLinkedList. You only need to write the recursive function.

Explain why airlines price discriminate. Describe the various degrees of price discrimination. For example, why would an airline lower price for special weekend getaways or for senior citizens?

The Chocolate Ice Cream Company and the Vanilla Ice Cream Company have agreed to merge and form Fudge Swirl Consolidated. Both companies are exactly alike except that they are located in different towns. The end-of-period value of each firm is determined by the weather, as shown below. There will be no synergy to the merger.

The weather conditions in each town are independent of those in the other. Furthermore, each company has an outstanding debt claim of $580,000. Assume that no premiums are paid in the merger.

a. What are the possible values of the combined company? (Do not round intermediate calculations.)

b. What are the possible values of end-of-period debt and stock after the merger? (Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations.)

c. How much do stockholders and bondholders each gain or lose if the merger is undertaken? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations.)

Students performed a procedure similar to Part III of this experiment (Analyzing a Vitamin Supplement for Vitamin C Content) as described in the procedure section. A 1.043g vitamin C tablet is crushed, treated, and diluted to 100.00mL in a volumetric flask with deionized water. Three 5.00mL samples of this solution are titrated with DCP that had a standardized concentration of 9.93x10^-4M. The three titrations took an average of 35.52mL of DCP. (MM Ascorbic Acid = 176.124 g/mol)

Calculate the mass (in mg) in the vitamin C tablet. (MM Ascorbic Acid = 176.124 g/mol)
