Company XYZ makes widgets. They will have 500 widgets to sell in 6 months. The current price is $60 per widget. The company's cost to create each widget is $40. The company decides to insure its position. The company has the following two options to hedge its risks: enter into a forward contract with a forward price of $61.80 or buy a 6-month $60-strike European put option for a premium of $5.25. The risk-free rate is 6% convertible semiannually. For what range of prices in 6 months would profit for option (1) be greater than the profit for option (2)? A. 56.39 to ∞ B. 0 to 67.05 C. 67.05 to ∞ D. 0 to 67.21 E. 67.21 to ∞

8. a) - What is the formula for nitric acid? - What kind of acid is nitric acid (strong or weak)? - Calculate the [H+] and the pH of a solution of 0.407 M nitric acid. b) - What is the formula for acetic acid? - What kind of acid is acetic acid (strong or weak)? - Calculate the [H+] and pH of a solution of 0.407 M acetic acid. c) - Compare your results from 8(a) and 8(b). - Which acid has the lower [H+], nitric acid or acetic acid? - Which acid has the lower pH, nitric acid or acetic acid? d) - What is the formula for sodium hydroxide? - What type of base is sodium hydroxide (weak or strong)? - Calculate the pH of a solution of 0.407 M sodium hydroxide. e) - What is the formula for sodium acetate? - What type of base is sodium acetate (weak or strong)? Note: Sodium acetate is a salt that completely dissociates in water to form sodium ions and acetate ions. Also note that acetate ion is the conjugate base of acetic acid. - Calculate the pH of a solution of 0.407 M sodium acetate. f) - Calculate the pH of a solution that contains 0.407 M acetic acid and 0.407 M sodium acetate. Hint: First, set up the typical weak acid equilibrium for acetic acid. Then, instead of "0" for initial acetate ion on the product side, you will have 0.407 M from the sodium acetate. Then calculate x as usual for the [H+].
