4 FeS2(s) + 11 O2(g) → 2 Fe2O3(s) + 8 SO2(g) ΔH = -3307.9 kJ

2 H2S(g) + 3 O2(g) → 2 H2O(l) + 2 SO2(g) ΔH = -1125.2 kJ

4 FeO(s) + O2(g) → 2 Fe2O3(s)   ΔH = 578.2 kJ

2 Fe(s) + O2(g) → 2 FeO(s) ΔH = -544 kJ

H2(g) + S(s) → H2S(g) ΔH = -20.2 kJ

2 H2(g) + O2(g) → 2 H2O(l) ΔH = 571.7 kJ

By combining the above equations calculate the ΔH(formation) of FeS2(s).

Exercise 13A-2 Net Cash Provided by Operating Activities [LO13-4] Wiley Company’s income statement for Year 2 follows: Sales $ 150,000 Cost of goods sold 90,000 Gross margin 60,000 Selling and administrative expenses 40,000 Income before taxes 20,000 Income taxes 8,000 Net income $ 12,000 The company’s selling and administrative expense for Year 2 includes $7,500 of depreciation expense. Selected balance sheet accounts for Wiley at the end of Years 1 and 2 are as follows: Year 2 Year 1 Current Assets Accounts receivable $ 40,000 $ 30,000 Inventory $ 54,000 $ 45,000 Prepaid expenses $ 8,000 $ 6,000 Current Liabilities Accounts payable $ 35,000 $ 28,000 Accrued liabilities $ 5,000 $ 8,000 Income taxes payable $ 2,000 $ 2,500 Required: 1. Using the direct method, convert the company’s income statement to a cash basis. 2. Assume that during Year 2 Wiley had a $9,000 gain on sale of investments and a $3,000 loss on the sale of equipment. Would these transactions affect the computation in (1) above?

In a Union-Management negotiation, the following are the annual percentages of wage increases for Union for various combinations of union and management strategies:

Management

M1 M2 M3

U1 1 3 3

U2 4 2 2

Union U3 3 2 3

U4 3 4 1

U5 2 1 2

9a. (5 points) After eliminating all possible dominated strategies, list the Union payoff matrices for the 4 subgames that are developed by taking 3 of the 4 Union strategies to match the 3 Management strategies.

9b. (5 points) Find the best strategy and value of the game for Union with the following payoff matrix for one of the subgames:

Management

M1 M2 M3

U2 4 2 2

Union U3 3 2 3

U4 3 4 1

9c. (10 points) We have solved in class the best strategy and value of the game for Union with the following payoff matrix for one of the subgames:

Management

M1 M2 M3

U1 1 3 3

Union U3 3 2 3

U4 3 4 1

Let q1, q2, and q3 be the respective probabilities for Management to play strategies M1, M2, and M3. Then use the same Principle of Maximin as in deraiving the best mixed strategy for Union to find the best strategy and value of the game for Management. Specifically,
