[Q]: The Schlenk equilibrium, which can be affected by the presence of dioxane, describes the stability of these compounds, whose synthesis can be improved by the addition of mercuric chloride amalgamates. They react with nitriles to form intermediate imine anions, and dry carbon dioxide can be bubbled through them to create carboxylic acids, which themselves do not form an addition product with these. In what is sometimes called their namesake's reaction, they act as strong nucleophiles to form tertiary or secondary alcohols from ketones or aldehydes. For 10 points, name these compounds formed by reacting an alkyl halide with magnesium, named for a French guy.
[A]: Science

[Q]: In solid-state physics, a dimensionally-equivalent "sheet" version of this quantity is often reported as its value "per square". Its quantum is equal to h over e squared, and the Drude model gives this extensive quantity as inversely proportional to the product of carrier number density and mobility. A complex version of this quantity includes a term equal to frequency times inductance. The power dissipated in a circuit equals (*) current squared times this value. Voltmeters work by applying a very large value for this quantity in parallel. Devices that provide this quantity are marked with a series of colored bands and symbolized with a zig-zag line. For 10 points, name this quantity set equal to voltage over current in a law named for Ohm, who also names its SI unit.
[A]: Science

[Q]: This book's epilogue discusses the "urge to go further" by considering the disciple of Heraclitus who remarked that one cannot walk through the same river even once. In the preface, the author admires Descartes for refusing to "make it obligatory for everyone to doubt" and instead claiming that his method had significance only for him. The "Exordium" discusses the mother who has to blacken her breast to wean her child, and imagines a man who prefers that his son think him a monster rather than lose faith in God. Later sections include a "Preliminary Expectoration" and a series of "problema" which consider such questions as "Is there a Teleological Suspension of the Ethical" FTP, name this work ostensibly written by Johannes di Silentio, a "dialectical lyric" which deals with the sacrifice of Isaac and was really penned by Soren Kierkegaard.
