A food company plans to conduct an experiment to compare its brand of coffee with that of two competitors. A single person is hired to taste each of three brands of coffee, which are unmarked except for identifying symbols, A, B, and C. The taster will rank the three coffees from most desirable to least desirable, with no ties. If the taster cannot distinguish taste, assume all six rankings are equally likely. (3 pts each) a. Define the experiment. b. List the simple events in the sample space S. c. If the taster has no ability to distinguish difference in taste among coffees, what is the probability that the taster will rank coffee type C as the most desirable? As the least desirable?

Mechanism: Provide a detailed, stepwise mechanism for the following dehydration reaction using concentrated sulfuric acid. Use curved arrows to show the movement of electrons.

Below are the  1H,  13C and DEPT spectra for a molecule with molecular formula C10H12O2. Deduce the structure of this molecule and assign all  1H,  13C and DEPT signals. Assign integration values and determine coupling constants (J-values) for all multiples. 

Heroku Industries has a SQL Server database that provides data to clients throughout its network. It has now asked George, a network engineer, to sort an issue within the administration branch where the Windows firewall does not allow access to the users to such databases. Analyze what port should George open up in the firewall so that the issue is resolved.

Identify compounds A through E in the following reaction scheme:

Was the Metz Republic (1234–1452) part of France, and who ruled it?

The volume of a solid is determined to be 15.4 L. How many gallons (gal) would this be? Conversion Factors:    1 liter (L) = 1.057 quarts (qt) 1 gallon (gal) = 4 quarts (qt) To earn full credit, show your work using Dimensional Analysis and report answer to correct number of significant figures. It can be helpful to create a table to show your work like the one below.   Sample Table for Dimensional Analysis        

Provide the structures of the products and clearly indicate the stereochemistry. (Assume the kinetic product will be major).

True or false? Medieval architecture is known for its round arches and Renaissance architecture is known for its Gothic style.

In which country do many Metz inhabitants work to increase their spending power in France?
