As of the writing of this text, EPA standards limit atmospheric ozone levels in urban environments to 84 ppb. How many moles of ozone would there be in the air above Los Angeles County (area about 4000 square miles; consider a height of 100 m above the ground) if ozone was at this concentration?

In this question you are going to calculate the data that could be used to construct a titration curve (pH versus volume of titrant added) for the titration of an aqueous ammonia (NH3; weak base, pKB = 4.7) cleaning solution with a strong acid (HCl). When strong acid is added to an aqueous solution, it immediately reacts and yields H3O + ions; thus the titration is described by the reaction: NH3(aq) + H3O + (aq)  NH4 + + H2O(l) K = 2.0x109

The cleaning solution is produced by adding 0.02 moles of NH3 to 1.0 L of pure H2O, which you later titrate with 1.0 M HCl titrant solution. To simplify matters we’ll assume all activity coefficients = 1.0 for all species in this problem. Utilize the ICE (INITIAL, CHANGE, EQUILIBRIUM)Table Method (show your work) to determine the pH of the system when various amounts of the strong acid (titrant) have been added. Note: when you solve the quadratic function, make sure to select the root that is positive, and if you have two positive roots, use the root that represents a realistic change; i.e. the change isn’t greater than what was physically added to the system or greater than the concentration of reactant it reacts with.

a. Calculate pH of solution when 0 mL of titrant have been added (only the NH3 has been added)

a1. Calculate pH of solution when 10 mL of titrant have been added

When creating a titration curve for a weak base, the pH of the initial solution requires setting up a table showing the initial, change, and equilibrium values for each species and plugging these into the equilibrium constant expression. The expression for the bicarbonate ion is Ka1=[H2CO3][H+][HCO3−] For an anion that can both hydrolyze and produce H+, the pH of a concentrated solution can be more easily approximated using the equation pH=12(pKa1+pKa2) During the titration before the equivalence point, provided that the concentration of acid is significantly more than the concentration of base, the Henderson-Hasselbalch equation can be used to approximate the pH: pH=pKa+log[base][acid] At the equivalence point, the solution is no longer a buffer, but contains the weak acid H2CO3. The change in concentration of the bicarbonate ion is significant, and the equilibrium constant expression for Ka1 must again be used to find the concentration of hydronium ions. After the equivalence point, the strong acid will control the pH.

Part A

A 10.0-mL sample of 1.0 M NaHCO3 is titrated with 1.0 M HCl (hydrochloric acid). Approximate the titration curve by plotting the following points: pH after 0 mL HCl added, pH after 1.0 mL HCl added, pH after 9.5 mL HCl added, pH after 10.0 mL HCl added (equivalence point), pH after 10.5 mL HCl added, and pH after 12.0 mL HCl added.

18. Armond is a shareholder of Brix and Mater Hotel Corporation. For the last few years, business has not been profitable for Brix and Mater. The firm has lost money on its operations. There has been some profit through sales of company assets, but the board of directors has refused to declare a dividend. This last year, the firm’s accountants failed to file fed­eral in­come tax returns and the board refused to pay the tax. Armond takes a close look at the firm and protests to the board, in particular over the fail­ure to declare a dividend, but the board ignores the complaint.

a. Which of these events, if any, would form a ground for a court to order the dissolution of Brix and Mater, on Armond’s petition?

b. If the court denies the petition, could Armond and the other shareholders dissolve Brix and Mater?

Work & Rest is an all inclusive hotel operating as a monopoly in a mid-sized community. The manager estimates that the hotel's total costs are described by the equation C = 0.1Q² + 20Q + 5000, where Q is the number or persons serviced and P is the price paid per person. Although it is located in a mid-sized community, it is close to a major highway that runs along the east coast. Often times, travelers would use the services of Work & Rest as a stop in their commute between two major citys. As such, the market demand for its service is described by the equation P = 170 - 0.2Q.

1. Given the current market conditions, Work & Rest's profit-maximizing quantity is  and the price charged per person is  ( 4 points)

Consider that after a series of reports from special interest groups, the local government decides to regulate Work & Rest by using the optimal pricing policy.

2. Given the successful implementation of the government's policy, Work & Rest's profit-maximizing quantity is  (2 points)

3. Given the successful implementation of the government's policy, what is Work & Rest's profit at its profit maximizing quantity?  (4 points)I

4. If the policy remains in place, and there are no further external shocks to the market, is it likely that West & Rest will continue to operate and provide service? (In the space provided enter will or will not)

In the long run, West & Rest  continue to provide service in this mid-sized community
