Pheophytin (shown below) is present in chloroplasts of green plants. In fact, it floats in the thylakoid membrane, in between photosystem II and photosystem I. Its role is simply to transfer electrons from one antenna (PS II) to the other (as described in class today). Pheophytin absorbs visible light because it contains a highly extended -system with electrons that can easily be excited to “low-lying” * antibonding orbitals.

a. Circle the part of the molecule that absorbs the photon. b. Count up the -electrons in that portion of the molecule, and indicate whether the nitrogen- containing ring structure is aromatic (according to the 4N+2 Huckel Rule). c. Propose a structure for the product formed by one electron reduction of pheophytin.

Homework Assignment #1For each problem, include a PDF version of anyspreadsheet output, etc., and clearly indicate your finalanswers.(Problem 1 – use Excel)The van der Waals (vdW) equation is a cubic equation ofstate which may be used to calculate the volume oressure conditions for a real gas:RTP =aHere, v represents the molar volume of the gas, and P, R,and T are the absolute pressure, ideal gas constant, andabsolute temperature of the gas, respectively. The valuesa and b may be calculated using:a =27 R2TZand1 RTC64 Pcb=8 PcSo, when both the critical pressure (Pc) and criticaltemperature (Tc) are known, one can apply the vdW togia more accurate calculation than the ideal gas law.CHEN-200 COMPUTATIONAL METHODS IN CHEMICAL ENGINEERINGHW #1a) Calculate the molar volume (L/mol) of propanec= 42.0 atm, Tc = 369.9 K) at 1 atm and 25 cb) Calculate the molar volume (L/mol) of nitrous oxidec= 71.3 atm, To = 309.6 K) at 10 atm and 200′

Homework Assignment 4

MAT 510

project where you used a problem-solving approach to address what turned out to be common-cause variation, or where you used a process improvement approach to deal with a special cause.

If you do not have a personal experience that echoes either of these situations, you may use the Internet to search for a case that reflects either of these situations.

Examples:

• one’s personal investment strategy since 2008
• reducing waiting times at the local hospital or emergency room
• reducing difficulties trying to connect to a Wi-Fi Internet provider

following questions in the space provided below:

1. Describe the experience in the project.
2. What were the solutions used to address the problem?
3. Was the case you described a special-cause or common-cause?
4. Do you feel the solution or approach used appropriate for the cause?
5. What would you do if you could do it again?
6. What conclusions can you draw from the problem-solving or process-improvement techniques?

Note: You may create / or make all necessary assumptions needed for the completion of this assignment. In your original work, you may use aspects of existing processes from either your current or a former place of employment. However, you must remove any and all identifying information that would enable someone to discern the organization(s) that you have used.

Assignment 2: Intervening With Peer Violence

Watch the following video Bullying: What Every Adult Needs to Know. Be sure to take notes as you watch as you will apply what you learn to the following questions:

1. At times we have heard bullies say that they did not intend to cause any problems with their peers and that they were merely having fun. They may indicate that the child who says they are the victim of bullying is overreacting. How should schools or other adults respond to this statement?
2. Compare the characteristics of those who are bullies to the victims of bullying. Describe a scenario that could result in a bullying incident when children with these characteristics come into contact with each other.
3. How can teachers and parents be involved in monitoring bullying behavior and what actions should they take if they suspect a child has become the victim of bullying?
4. Describe an intervention program that you would develop to address the behavior of children who are bullies and explain your rationale.
5. Discuss how issues of gender and diversity might be reflected in bullying incidents of bullying.

Submit your response to the W4: Assignment 2 Dropbox by Week 4, Day 7. Your response should be 3-5 pages long and include a cover page and reference list.
