Why do firefighters recommend the use of a deluging volume of water when extinguishing an oxidizer-supported fire? What may happen to a large (i.e., 30-50lb) container of trichloro-s-triazinetrione, or calcium hypochlorite, if it is left to sit in the wa
Write an abstract for the “Gravimetric Determination of Calcium” experiment you just completed using the guidelines below. Because of the simplicity of the experiment performed, your abstract should be between 150 and 250 words, which is less than the typical abstract. As before, your written abstract should be typed, double spaced, and written […]
7. Tim and a friend left a campsite on a trip down a river in a canoe, maintaining a constant speed of 4 miles per hour. Four hours later, Tim’s father set out after them in a motorboat carrying the camping supplies. The motorboat traveled at a rate of 12 miles per hour. How long […]
The best means of personal protection from radiation for emergency responders is the implementation of three basic principles: time, distance and shielding. Please show your work when answering the following questions: a. Using the inverse square law of radiation, what Geiger counter reading would you get for a radioactive material when you are 3 feet […]
1. A gas has a volume of 800.0 mL at minus 23.00 °C and 300.0 torr. What would the volume of the gas be at 227.0 °C and 600.0 torr of pressure? 2. 500.0 liters of a gas are prepared at 700.0 mm Hg and 200.0 °C. The gas is placed into a tank under […]

You have an unknown sugar. It is a D-aldohexose with an “S” stereocenter at the “first” chiral carbon. You treat the sugar with nitric acid. The resulting compound is optically active. You perform Wohl-Degradation on this sugar (1. NH2OH, 2. Acetic Anhydride, 3. OH-), and then subject the resultant sugar to nitric acid oxidation. The resultant sugar is optically inactive. […]
