The Promises and Perils of Nuclear Power

/in /by

The term nuclear power refers to the production of electrical energy via controlled nuclear reactions. These reactions generate heat that, in turn, creates steam that runs the generators to produce electricity. Approximately 1/8th of the electricity produced in the world is derived from nuclear power. In this assignment, you will analyze the use of nuclear power as an energy resource.

Respond to the following:

  • Discuss the scientific and technical concepts related to the use of nuclear power as an energy resource. Address the following in your response:
    • How is energy released in a nuclear reaction?
    • How are nuclear reactions controlled?
    • What elements are involved in nuclear power production?
    • What nuclear forces are involved?
  • Explain the advantages and disadvantages of nuclear energy, detailing issues related to production, delivery, cost, radiation, air quality, and waste.
  • Identify a country whose electricity production infrastructure relies heavily on nuclear power. Compare and contrast the use of nuclear power in the United States with the use of nuclear power in this country. Provide examples of the use of nuclear power in your community or state.
  • Consider the three major nuclear accidents in the history of the industry: 3-Mile Island (USA), Chernobyl (Ukraine), and Fukushima Dai-Ichi (Japan). What lessons have been learned from these nuclear accidents that can be or have been used to make nuclear power safer?

What is Pete’s monthly take home pay and indicate the amount his check was under or overstated. What is his weekly traveling expenses?

/in /by
Pete earns $1400 salary per month plus a 9.5% commission on sales over $1500. He had $8250 in sales last month. His traveling expense is 16% of his weekly earnings before commissions. He believes that his check for $1460.47 is in error. Monthly deductions include social security 126.56, medicare 29.60, fit 239.39, union dues 25.00, and health insurance 16.99.

A. A bullet leaves a rifle with a muzzle velocity of 521 m/s. While accelerating through the barrel of the rifle, the bullet moves a distance of 0.840 m. Determine the acceleration of the bullet (assume a uniform acceleration). B. Ima Hurryin is approaching a stoplight moving with a velocity of +30.0 m/s. The light turns yellow, and Ima applies the brakes and skids to a stop. If Ima’s acceleration is -8.00 m/s2, then determine the displacement of the car during the skidding process. (Note that the direction of the velocity and the acceleration vectors are denoted by a + and a – sign.)

State Capitalism, the Chinese model, presents competitive challenges to the free-market private ownership type of economic model. Regulations are important but what about control? How does regulation work when the government owns the business? And what model works best in a global environment, State Capitalism or Pure Capitalism?

Programming Assignment 2

due Saturday, Nov. 17, noon, 2012

The basic task is this: implement a stack of float values that has Θ (1) worst case behavior for PUSH, POP, and MEAN, a function returning the mean of the values in the stack.

This stack should be wrapped in a user interface that asks the user to choose from POP, PUSH, MEAN or QUIT at each turn. If the user enters PUSH, the program should read a number from the keyboard. If the user tries POP or MEAN on an empty stack, the program should notify the user of the error, and again prompt the user to choose from POP, PUSH, MEAN or QUIT. To facilitate testing, please use exactly these commands.

Assignment 1: HR Management

 

Due Week 2 and worth 125 points

 

Imagine you are the HR manager at a company, and an employee came to you upset because she felt a male co-worker had sexually harassed her by repeatedly asking her out on dates even after she said “no.” What would you do?

 

Write a one (1) page paper in which you:

 

  1. Formulate the conversation you would have with the employee, based the concepts found in Chapter 2 in your textbook.
  2. Summarize the conversation you would have with the employee’s male co-worker, based on the concepts found in Chapter 2 of your textbook.
  3. Format your assignment according to the following formatting requirements:
    1. Typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.
    2. Include a cover page containing the title of the assignment, your name, your professor’s name, the course title, and the date. The cover page is not included in the required page length.

6 Questions Chemistry Homework

1. The methane, CH4(g) reaction and associated thermodynamic data at 298 K are given below.

 

CH4 (g) + 2 O2 (g)CO2 (g) + 2 H2O (l)

DGorxn= – 818kJ/mol

DHorxn= – 890kJ/mol

DSorxn= – 242 J/molK

 

Suppose that you start with 1 atm CH4, 0.2 atm O2, and 0.00038 atm CO2. How does the maximum non-expansion work compare with standard conditions? Provide a thermodynamic justification to your answer.

 

2. Solid Ni metal (melting point 1728 K) has the amazing ability to react with gaseous carbon monoxide, CO(g), at 323 K to form a volatile, colorless liquid, Ni(CO)4 (boiling point 316 K). Ludwig Mond – the person who made this discovery-described the reaction as ‘giving wings to the metal’.

 

Ni (s)+4 CO (g)Ni(CO)4(g) DHorxn= -161 kJ/mol

Given that DSOrxn = -410 J/molK, calculate the value of DGOrxn at 25OC.

 

3. Considering the data above, and given that for the process Ni(s)Ni(g) DHOvap = +430 kJ/mol, determine the bond enthalpy for a Ni–CO bond.

 

4. Suppose that you place 1 atm of Ni(CO)4(g) in a closed container with a trace amount of CO (PCO=0.002 atm) at 25OC and allow it to reach equilibrium. What changes, if any, do you expect to observe when the reaction mixture is allowed to reach equilibrium? Explain your reasoning.

 

5. Mond developed a practical two-step separation scheme to obtain pure nickel metal from a mixture of nickel with other metals that do not undergo the same reaction, using only carbon monoxide. If the first step involves formation of pure gaseous Ni(CO)4 from the mixture, based on the thermodynamic data above, what do you think might be the final step to obtain pure Ni metal? Use a thermodynamic argument to justify your answer.

 

6. Consider the evaporation of water at 298 K and 1 atm pressure, H2O(l) -> H2O(g). The standard free

energy of this reaction is: DGOrxn = +8.6 KJ/mol. If the partial pressure of water in the air on a dry (non-humid) day at 298 K is 0.001 atm, calculate DGrxn and state whether the above process (i.e. evaporation of water) would proceed spontaneously. Show how you arrived at your answer.
