Document Summary

So with a few announcements, the test opens up tomorrow at noon and closes friday at noon, you need to take integrity statements, namely that you can confer with each other during or after the test. So let me tell you the integrity statement . What i"m going to be posting up right now is what you will see before taking the test. Can everyone see where it says general information. The time period is 2. 5 hours, so it will close automatically after 2. 5 hours. Be careful that you only have 2. 5 hours. You have our emails here, and i will discuss technical issues. You may use your calculator, lecture notes, textbooks and assigned readings. You can use any course related material, including, lab/class recordings. What you can"t do is talk with your classmates about anything from the test or anything from the test, during or after.

Electrophilic Aromatic Substitution help needed. Objectives: Design an experimental procedure that allows you to determine the relative reactivity between anisole, chlorobenzene, diphenylether, toluene, ortho‐xylene, meta‐xylene and para‐xylene.

In this lab you are challenged with determining the relative rates for reaction between different substituted benzenes and a common electrophile (Br2). Bromine was chosen as the electrophile because it is colored. Acetic acid (solvent), and all of the substituted benzenes we will be using are colorless. Also all products, HBr and the brominated substituted benzenes are all colorless. Thus we can know when the reaction is complete if we use bromine as the limiting reagent and watch for the color to disappear. Before you come to lab you must develop a plan to test relative rates of reactions of anisole, chlorobenzene, diphenyl ether, toluene, m‐xylene, o‐ xylene and p‐xylene with bromine. In the lab you will be provided with 0.20 M solutions of each of the substituted benzenes, and 0.05 M solution of bromine. You have your standard glassware found in your drawer, and we ask that you use no more than 1 mL of any given solution for any given test (this means you can use 1 mL of Br2 to test anisole and another 1 mL . Working on this scale would require small reaction vessels, so I would recommend carrying out individual tests in 3‐inch test‐tubes (your small ones). They can easily be held in a water bath by wrapping a coil of copper wire around them and putting a hook in the wire that catches the top of a beaker (see figure). If you need to explore different temperatures, we recommend using a beaker of boiling water as a 100oC bath, a beaker of ice and water for a 0oC bath and a beaker of tap water that has been left out for 20 minutes or so as a room temperature bath which can be monitored with a thermometer. We also have stopwatches and a clock that you can use to measure time. With these resources available, come up with a plan to determine experimentally the order of reactivity between the above substituted benzenes. To accurately determine this order you will have to take great care to ensure that all other variables are consistent between different tests.

can anyone help with this really super basic lab? Feel free tomake up data, highschool level information please!

You are NOT limited to the suggested projects listed below.Think up your own unique research project!!

Projects should involve observation/measurement of livingorganisms-plants, animals, fungi, humans. They should be designedto answer a question or to test a hypothesis. Examples ofhypotheses would be; "Plants will grow more if there is morerainfall" Or "Students will get higher grades if they study more."Sample size is important when possible; make multiple measurementsof several individuals. Your project must be something thatproduces DATA that can eventually be graphed. There should be adependent variable and an independent variable. For example,"amount of rainfall" would be an independent variable and "how fastplants grow" the dependent variable.

Projects should take approximately three hours, total, tocomplete, not counting the write up, which will be a separate lab.Detailed instructions on writing your report are attached. Keepyour project simple and manageable. Submit your first project bythe due date for Project 12 (July 7th)**Please make sure that yourassignment gets to me by the due date. You will still be able toupload your assignment after the due date, but it will be marked aslate, and you will lose some points for being late.

A few examples of projects:

Is there a correlation between the size of a dog, and how longit lives? For this you will need about ten dead dogs! Ask aroundamong friends, classmates, family, about dogs that died a naturaldeath. Find out each dog's age at death, and approximate weight. Alarger sample size here would be even better. Can you explain thecorrelation?

Do humans have a physiological response (difference in pulse,blood pressure, etc.) to music? Choose three different categoriesof music, such as classical, folk, rock, or none (silence). Have atleast five people in your study, and measure their pulse (or bloodpressure) both before and after they have listened to the music for5-10 minutes. Graph the increase (or decrease) in their pulse forthe different types of music. GRAPH THE AVERAGE values for yoursubjects, not value for each individual.

Is there a correlation between a person's usual amount of sleep,and how well they perform on memory tasks? Devise a SIMPLE memorytest-it could be just to study a list of twenty random words, andthen to recall as many as possible. Give this test to at least fourpeople who usually get (a) less than 6 hours sleep, (b) 6-7 hourssleep and (c) 8 or more hours. Or, choose your own categories.Amount of sleep is your independent variable (X axis) and AVERAGEscores on the test, the dependent variable. (Y axis). GRAPH THEAVERAGE!

Include ALL relevant observations and information in precisedetail. If possible, include illustrations of your experiment, yoursubjects, your work in progress, etc.

Format for writing your Research Report:
1. Introduction

SEC Web Site Demonstration

Demonstrate how to locate SEC data and various financial statements.

Select any publicly traded organization (e.g., your employer may be a good choice). Locate the organization on the SEC’s Web site at http://www.sec.gov. Use the EDGAR database on the SEC Web site to view the organization’s 10k filing. Also, search for the company’s standard industrial classification (SIC) code. Retrieve the different financial statements in the 10k filing. Check out the footnotes in the financial statements. Discuss any emerging issues that are evident on the SEC Web site.

Let's do an example in case you have trouble. You will need to write this down or print it out somehow so you can use this example to get to the information.

Click on the SEC Link in the instructions; it will take you to the SEC Home page. You can explore that for a while. But to get to our sample information, in the second column and under the second blue bar "Filing & Forms (Edgar)" click on "Search for Company Filings".

On that page under "General Purpose Searches" click on "Companies and other Filers".

On the next page type "Wal Mart" (without quotes and make sure you put in the space and do not use a "-"; just Wal Mart) the click on "Find Companies" at the bottom of the box.

Now see "Wal Mart Stores Inc?" Note the SIC Code just below it.

Click then on the 0000104169 and take a look at all the information there. Look down the page at all the information filed by Wal Mart with the SEC. Note you do not see a 10K form???? Click on "Next 40." Not too far from the top you will finally see the 10K!!! Click on "html" for the 10K then on the next page to get to the beginning of it click on "d10K.htm." You are there. Wal Mart's most recent 10k will come up.

Explore this; it is quite long and quite detailed. I suspect you will be amazed to see how much information a company must share with the world and how much is available to you if you go looking. Take a good hard look over this document.

Do some research on this site to tell us just what a 10K is?

Give it a try, and then try another publicly traded company. Try a big one; it will be easier for you to isolate. If you cannot get any further than Wal Mart, you can discuss what you find about them for this assignment. However, TRY to select different companies so the entire class is not researching the same company. We will all learn more this way.
