question:
In 1997 Edwin Hall wrote a book about this work which discussed the inclusion of St. Margaret emerging from the belly of a dragon, which can be seen carved above the back of a chair, to argue that Erwin Panofsky's influential interpretations are too simplistic. Commissioned by its subject, a counselor to the Duke of Burgundy who made his money as a silk merchant, the year and the artist's signature can be seen above the mirror whose reflection depicts the artist himself. That artist would go on to paint other famous portraits like The Madonna with the Chancellor Rolin. Filled with details like a lit candle, a little dog, and a pair of discarded clogs, FTP, identify this work that depicts a man dressed in dark heavy wool and a big hat holding the hand of his betrothed, a painting by Jan van Eyck.
answer:
Fine Arts


question:
To isolate volatile compounds from nonvolatile impurities, the steam form of this process is used when the compounds decompose at standard temperatures and pressures. Two miscible liquids are heated under a Liebig condenser to increase the concentration of the liquid with the lower boiling point in a common type of this process. FTP, name this separation method by boiling point, whose fractional variety yields cosmetics from petroleum and alcohol from a water mixture.
answer:
Science


question:
Chris Wright was the first person to use this reaction with coordinated carbon dioxide nickel complexes and Nguyen performed "green" versions of this reaction without solvents to create ethyl trans-cinnamate. Used in the preparation of steroids, this reaction can also be used to produce large yields of unsaturated nitriles. Using excess lithium salts during the addition step allows selective formation of the product and is known as the Schlosser modification. For 10 points, name this reaction that reacts an aldehyde or ketone with an ylide to generate an alkene.
answer:

Science
