Such is life...

The 2008 CH 121 final exam cover sheet is identical to the 2007 final exam cover sheet. Our CH 121 final exam is scheduled for 7:30am on Tuesday, December 9, 2008. The exam period is from 7:30-9:20am (Good Morning!). The exam is approximately 40 questions. About 1/3 of the questions cover the Exam 1 objectives (read as: similar to Exam 1 questions). About 1/3 of the questions cover the Exam 2 objectives (read as: similar to Exam 2 questions). About 1/3 of the questions cover the Quantum objectives (our material from Chapter 7 and part of Chapter 8). Students have found it valuable to print out and retake Exam 1 from October and Exam 2 from November.  These and the keys are still available from the Exams Information link (http://www.chem.orst.edu/courses/ch121-3/ch121/ch121examinformation/ch121exam.htm). Check your solutions and brush up on these concepts. To study for the last third of the exam, practice past final exams (http://www.chem.orst.edu/courses/ch121-3/ch121/ch121examinformation/ch121exam.htm), complete OWLs, complete Worksheets, and discuss concepts.

Many students significantly increase their course standing with a tremendous final exam score. The exam policy is:

If you write a higher percentage score on the final exam than on the midterm exams, the final exam percentage will be used as a score for all three term exams. There is nothing to sign-up for. It is an automatic win-win situation. This is a mechanism which gives students who experienced educational difficulty during the term for any reason a chance to demonstrate that they have mastered the material and to profit from that mastery.

How Many? A Dictionary of Units of Measurement © Russ Rowlett and the University of North Carolina at Chapel Hill

The Metric System in the United States

Article I, Section 8 of the U. S. Constitution gives Congress the power to "fix the standard of weights and measures" for the nation. The First Congress, meeting in 1789, took up the question of weights and measures, and had the metric system been available at that time it might have been adopted. What actually happened is that Thomas Jefferson, who was then serving as the first Secretary of State, submitted a report proposing a decimal-based system with a mixture of familiar and unfamiliar names for the units.

Jefferson's system actually resembles the metric system in many ways. Its biggest shortcoming is that Jefferson didn't hit on the idea of using prefixes to create names for multiples of units. Consequently, his system was burdened with a long list of names. For example, he divided his basic distance unit, the foot (it was slightly shorter than the traditional foot) into 10 inches. Each inch was divided into 10 lines, and each line into 10 points. For larger distances, 10 feet equalled a decade, 100 feet was a rood, 1000 feet a furlong, and there were 10 000 feet in a mile (making the Jeffersonian mile about twice as long as the traditional mile). His basic volume unit was the cubic foot, which he proposed to call a bushel (it was about 3/4 the size of a traditional bushel). The basic weight unit was the ounce, defined so that a bushel of water weighed 1000 ounces. (This is very similar to the metric system, in which a liter of water weighs 1000 grams).

Congress gave this plan serious consideration, but because it lacked independent support from other scientists it was easy to criticize. Ultimately, Congress took no action. This left Americans with a version of the traditional English weights and measures, including:

• distance measurements identical to those of the 1592 Act of Parliament,
• the traditional avoirdupois system of weight measurements,
• a system of measurement for dry volumes based on the "Winchester" bushel used in England for wheat and corn since the late Middle Ages, and
• a system of measurement for liquid volumes based on the English wine gallon of 1707.

It is remarkable that Congress never established this traditional system, or any other system, as the mandatory system of weights and measures for the United States. In 1832, Congress directed the Treasury Department to standardize the measures used by customs officials at U.S. ports. The Department adopted a report describing the traditional system, and Congress allowed this report to stand without taking any formal action. This is the closest the U.S. has ever come to adopting a single system of measurement. Ironically, the U.S. missed two opportunities in 1832. Americans could have adopted the metric system, which was then at an uncertain point in its history; or they could have decided to align their measurements with the British Imperial measures established by Parliament in 1824 and thus created a possible alternative to the metric system in international commerce.

Darling,

 

Before you return from your trip I wanted to let you know about the small accident I had in the pick-up truck.  Fortunately I didn't get hurt, so please don't worry about me.  When I turned into the driveway I accidentally pushed down on the accelerator instead of the brake.  The garage door is slightly bent but fortunately the truck came to a halt when it bumped into your car.  I am really sorry but I know with your kind hearted personality you will forgive me.  You know how much I love you and care for you my sweetheart.  I cannot wait to hold you in my arms again.

 

Your loving spouse,

 

XXXOOO

Army Humvees Can Produce Water

Delivery of water to an army in the desert is a costly and time-consuming effort. The military calculates that a soldier in the desert needs 20 gal of water a day, five of which must be pure enough to drink. It can take up to 40% of troops deployed in the field just to transport water and other materials, so it would be a great advance if another source of water were available. That source might be vehicle exhaust. Engineers at United Technologies Corp.'s Hamilton Sundstrand unit are building two Humvees for the Army that will extract and clean water directly from the exhaust. Although the idea is not new, the Army has spent millions to make it work. The water vapor and other gases in the exhaust from the modified Humvees are vented through a catalytic converter to eliminate as many impurities as possible, and then run through a pair of heat exchangers to condense the water. This blackish liquid is then passed through a series of six proprietary carbon filters that bring the quality up to about tap water. Finally, chlorine is added to kill bacteria and algae, and the water flows into a 5-gal tank with a spigot. The water can be chilled by the Humvee's air conditioner. It is estimated that a vehicle could produce about 1 gal of water for each 2 gal of diesel fuel burned. The company recognizes that a lot of development still needs to be done. The system can cost more than 20% of the cost of the vehicle, it weighs almost 500 lb, and the water filters need to be changed every 75 to 200 gal. Still, if such a system can help soldiers survive if they cannot get other logistical support, it sounds like a good idea.
