Chemical Engineering ChE 321 – Design Project 1 Pick A Rate Law, Any Rate Law The Scenario: Professor Z. O. Lite and his fabulously talented group of undergraduate chemical engineers at UND have developed a new catalyst. In preliminary studies it has dramatically increased the rate at which p-xylene is formed from the reaction of […]
Chemical reaction in solution Part I: Mechanisms (20 points). Reaction A: consider a solution of acetophenone (AKA methyl phenyl ketone) and sodium trifluoroperacetate (deprotonated trifluoroperacetic acid). Draw these two reactants and then show a full arrow-pushing mechanism providing the flow of electrons, showing how the two react with one another and the resulting product.

Explain why is important for you to know this information. […]
Discussion Board “To whom much is given, much is required” is a bible quote (Luke 12:48 ) which is often used to explain why we expect more from those who are born to some advantage. Compare the backgrounds of McBay, Henry C. Encyclopedia.com , Henry C. McBay Award (nobcche.org) and Dr. St. Elmo W. Crawford […]
Reparaphrase the lab report Objectives Given samples of acetylsalicylic acid, acetaminophen, caffeine, and ibuprofen, calculate the Rf values and melting temperatures. Identify solvent system that produces good separation. Identify an unknown analgesic using Thin-Layer Chromatography (TLC). Principle “Thin-layer chromatography is a method of separation, or identification of a mixture of components by using finely divided […]
ORGANIC CHEMISTRY LABORATORY I Separation and Purity Techniques: Thin-Layer Chromatography and Melting Point OBJECTIVES: 1) Investigate solubility of organo-metallic compounds 2) Advise a solvent system for proper separation of organo-metallic compounds on TLC plate 3) Determine the melting point of organo-metallic compounds Note: All background regarding TLC and melting point determination has been covered in […]
BIO&CHEM OF COOKING Red wine gets its color from anthocyanins found in grape skins, but other types of pigments may be produced during fermentation of the must. The production of some types of red-colored pigments, including visitin A and visitin B, are dependent on the production of pyruvic acid during fermentation. Examine the figure at […]
