/in Uncategorized /by adminIf you thought that getting 50 miles per gallon driving a toyota Prius hybrid was good, how about 230 miles per gallon? Or 367 mpg? Well, you are about to see a new breed of automobiles from big and small automakers touting this level of performance. In 2010, look GM’s Volt and Nissan’s Leaf, but there will also be offerings from unknown startups such as V-Vehicle, a California-based electric car company backed by billionaire T. Boone Pickens. These automobiles range from hybrids- a combination of gas and electric- to all electric vehicles. This level of performance comes at a high price, however. Although consumers will receive an expected $7,500 tax credit for purchasing one of these cars, the Volt’s expected $40,000 price tag will still cause sticker shock. Also, the lack of public recharging stations poses a singnificant challenge, especially for all- electric vehicles such as the Leaf, which needs recharging approximately every 100 miles. And some might question the efficiency claims, especially since the Environmental Protection Agency is still finalizing the methodology that factors in electricity used when making miles-per-gallon equivalency claims. 1. What factors in the marketing environment present opportunities or threats to automakers (AACSB: communication; reflevtive thinking) 2. Will it be possible for a startup automaker such as V-Vehicle to compete with big automakers such as Ford, GM, BMW, ect…? What factors in the Marketing environment will enable or inhibit new competitors? (AACSB: communication; reflevtive thinking)

Electrochemistry, Concentration and Cell Potential Electrochemistry involved oxidation and reduction
/in Uncategorized /by adminElectrochemistry, Concentration and Cell Potential
Electrochemistry involved oxidation and reduction reactions An oxidation reactioninvolves the loss of electrons (creating a more positive charge), whereas a reduction reactioninvolves the gain of electrons (creating a more negative charge) Redox reactions deal with the transfer of electrons between the materials being reacted, then leaving a residual charge once reacted When calculating total cell potential, the potential values of both the anodeand the cathodemust be determined Once that occurs, the formula below can be utilized to determine your E°cell value
E°cell = E°Anode + E°Cathode
At the anode (the negative electrode), oxidation occurs with a loss of electrons, creating a more positive charge on the anode At the cathode (the positive electrode, reduction occurs with a gain of electrons, creating a more negative charge This gain and loss of electrons can be expressed through half-cell reactionsand standard cell notation A half-cell reaction shows the gain or loss of electrons of a single system, whereas standard cell notation encapsulates both the anode and cathode and the electron transfers separated by a salt bridge (denoted by a double vertical bar in between ||) An example of a half-cell and a standard cell notation is outlined below Be sure to note that the anode is always listed first in standard cell notation

read each set of directions carefully
PART ONE:Use the data below to perform the calculations and tabulations needed
When conducting an electrochemistry laboratory exercise with your lab partner, you made multiple solutions of different concentrations of Copper Nitrate The concentrations that you made were 005 M, 010 M, 020 M, 050 M and 075 M, respectively by first calculating the dilution factors and diluting a 100 M stock solution accordingly An apparatus was made with a plastic cup assembly, a porous cup acting as the salt bridge, a stock 100 M Lead Nitrate, a copper electrode and a lead electrode The lead nitrate was placed inside of the salt bridge cup with the lead electrode and placed inside of the plastic cup assembly; each copper nitrate solution was then poured into the plastic cup, between the plastic cup and the porous salt bridge accompanying the copper electrode The voltage readings were recorded below:
Concentration of Copper Nitrate (M)
005
0012
010
00175
020
E°cell Reading (V)
0022
050
0040
075
0052
1 On a separate piece of paper, make a plot of the data above showing the concentration of Copper Nitrate vs the E°cell Reading Note the kind of relationship Provide a figure caption, axis labels, and a chart title
2 Suppose you were to conduct the same experiment but with a solution with an unknown concentration The voltage reading you recorded for the unknown was 0047 V With this information, draw a line of best fit of the data in question one From the line of best fit, determine the estimated molarity of the unknown solution and record it here: ____________
PART TWO:Nernst Equation
The Nernst Equation is a method of calculating cell potential by using the standard cell potential (E°cell), gas constant (8315 J/mol K), temperature in Kelvin (T), number of moles of electrons transferred during the reaction (n), Faraday’s constant (F = 96485335 C/mol), and the reaction quotient (Q) The equation is as follows:
Ecell = E°cell – (RT/nF)*ln(Q)
1 Calculate the cell potential of a galvanic cell made of lead and cadmium The molarity of the cadmium solution was 0200 M, and the molarity of the lead solution was 0100 M The temperature of the cell is 300 K
Cd?Cd2+ +2e- E°=+0403V Pb2+ +2e- ?Pb E°=-0126V
E°cell = _____________________
2 Calculate E°cell of a cell made of zinc and copper The molarity of the copper solution is 0300 M, the molarity of the zinc solution is 0150 M, Ecell is 148 V, and the temperature of the cell is 325 K

Part 1. Identify the Client
Step One this week is to identify a client for whom you will act as a consultant. The client can be your own work group or company, a family business you are involved with, a business you worked for previously, a volunteer organization you work for or have worked with, or a public company. The client you choose should be a small group or organization in which you can influence change in your role as a consultant. Please do not select “the military” or “the U.S. government” or “Giant XYZ Corporation.” However you may choose a small entity, such as a work group, within any of the larger organizations. For example, if you are in the military, focus on your group. If you select a Giant XYZ Corporation, select the department.
Part 2. Identify the Problem
Step two is to identify a problem or issue that is impacting performance in the organization. With your knowledge of the client you have identified and the learning you have acquired to this point, identify a management problem you will investigate and for which you will provide recommended solutions. If you are working with a supervisor or manager, you may want to consult with them to complete this step.
Read the material at the sites listed in the Week 1 Lessons folder (look for the Lessons tab on the l.h. side in this classroom) to help guide you in identifying a management problem in your work environment.
Complete a 2-4 page paper discussing the client and the management problem you will explore during this course.
