An insulated Thermos contains 200 cm3 of hot coffee at 88 °C. You put a 19.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment.

In a solution that would result if 0.200 moles of MgCl2 are combined with 0.200 moles of NaOH in a total volume of 1.00 liter:

a) Determine the concentrations of all ionic species in this solution.

b) Calculate the pH of this solution.

c) You could add 0.040 moles of NaOH to the solution in part (a), causing additional Mg(OH)2 to precipitate. Calculate the new pH that would result from this addition.

d) Or, you could add 0.040 moles of HCl to the solution in part (a), which would cause some of the Mg(OH)2 to dissolve. Calculate the new pH that would result from this addition.

Note: You should notice that the pH will only change slightly when a reasonable quantity of strong base or strong acid was added to this solution in parts (c) and (d)!

My table below provides the break-down of the market share from several brands different nutrition bar in 3 separate regions. In the Region UMCP, market shares of brand HS, SH, FE, GW are 50%, 40%, 10%, 0%, respectively. Compare degree of market concentration for each region from calculating the Herfindahl-Hirschman Index.

Know that there are 2 units of the Index: (from 0 to 1 vs from 0 to 10000). If the range is from 0 to 10,000, HHI is calculated by the percentage of the market share. If the range is from 0 to 1, calculate it by the fraction of the market share. There is a market that Brand A shares( 0.3= 30%) and Brand B shares (0.7=70%), the HHI is either 0.3×0.3 + 0.7×0.7 = 0.09+0.49= 0.58, or 30×30 + 70×70 = 5800.

(1) Calculate the HHI for each of the separate Regions.

(2) Compare the degrees of market concentration among the regions. (Order the degree of concentration or the degree of competition)

(3) What is the market structure of nutrition bar seen at Region UMES?

(Select 1 of the following and explain: Perfect competition, monopolistic competition, oligopoly, monopoly,  monopsony)

Marques (2010) said “Organizational communication has demonstrated to be a crucial aspect in the success rate of any type of organization, whether for-profit or non-profit, business or academic based” (p. 56).

 Is your current or former organization successful? Does the communication in your organization (current or former) reflect the level of success, or lack thereof? What can leadership do to ensure there is quality communication in organizations?
