Solution: zero
Explanation: The optimal level of output for a firm for maximizing its profits is a point where the market price equals the marginal cost. When marginal revenue and price is less than marginal cost, the firm would incur an economic loss on the marginal unit, thus would increase its profits by reducing the output; and when marginal revenue and price is greater than marginal cost, the firm would incur profit, but not to its maximum.
explain whether firm’s decisions are optimal if economic (a) positive, (b) zero, or (c) negative.

Chapter 3, Section 3.2, Question 017-018 For the function f (x) = a(x-r)(x-s) graphed below, state whether the constants a, r, and s are positive, negative, or zero. (Assume r S s.) a is r is
Indicate whether ΔS° is large and positive, large and negative, or nearly zero in each of the following reactions. (a) NH3(g) + HCl(g) → NH4Cl(s) large and positive large and negative nearly zero (b) N2H4(g) → N2(g) + 2 H2(g) large and positive large and negative nearly zero (c) H2(g) + I2(g) → 2 HI(g) large and positive large and negative nearly zero (d) HF(aq) + NO2− (aq) → F − (aq) + HNO2(aq) large and positive large and negative...
For the graph on the right, determine if the slope is positive, negative, or zero, and whether the y-value of the y-intercept is positive, negative, or zero. The slope is O A. negative. O B. zero. O C. positive. The y-value of the y-intercept is OA. negative. 10 10 B. zero. O C. positive.
3) Predict whether the change in entropy is positive, negative, or zero for each of the following reactions at 298 K, and explain your reasoning (2 pts each. 8 pts total): 1.4 Fe(s) + 3 O2(g) → 2 Fe:O:(s) b. O(g) + ( ) → O.(g) NH,Cl(s) » NH(g) + HCl(g) d. Hz(g) + Cl:(g) → 2 HCI c.
B. negative. C. zero. D. positive then negative. E. negative then positive. 16. A common statistic in car tests is the standing (starting from rest) quarter-mile performance. A modern sports car can achieve a terminal speed (speed at the end of the quarter-mile) of 120 mph (193 km/h). How does the average acceleration compare to g? (0.25 mile 402 m) A. 0.36 g B. 2.8 g C. 0.067 g D. 3.57g E. 0.73 g
1. In a perfectly competitive industry a). Draw a firm’s MC, ATC, AVC curves b). On the industry side, show the market price such that the firm is making a positive amount of profit. On the firm’s diagram, label the optimal output the firm will produce as q*, the profit this firm will make. c) Using another set of firm and industry diagrams, show the market price such that the firm is making zero profit. Label firm’s optimal output. Why...
Determine whether ∆H, ∆S and ∆G are positive, negative or zero for the following conditions: 1) a solution of methanol and hexane is prepared. 2) Sodium nitrate dissolves in water to a concentration lower than its solubility. 3) Hydrogen molecules dissociate into atoms at 300K. Explain your reasons for each decision, if there is insufficient data suggest extra data or information that may be needed.
