[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]: Seas of calcite predominate during times of low concentration of this element. The NIMS probe discovered that Ganymede has a sulfate of this element, which is also used to treat eclampsia. Its molten form is used to make metallic titanium in the Kroll process. The active site of rubisco contains a carbamylated lysine attached to an ion of this element. Its cationic form is used to stabilize the product of PCR, and it is also prevalent in certain reagents in a Schlenck equilibrium. It is found in Grignard reagents as well as coordinated to the porphyrin ring of chlorophyll. For 10 points, name this element with atomic number 12 and symbol Mg.
[A]: Science

[Q]: This general lost one battle when his subordinate, Adam Stephen, was intoxicated during it. He was sent to Fort Le Boeuf by Robert Dinwiddie. This man dramatically put on his spectacles while squelching the Newburgh Conspiracy. He was the senior American aide to Edward (*) Braddock on that man's ill-fated expedition and had previously been forced to surrender Fort Necessity. This man improved the skills of his troops by bringing in Baron von Steuben to train them. He made a dramatic evacuation after losing the Battle of Long Island. For 10 points, name this American general who led his troops to capture Hessians at Trenton after crossing the Delaware River on Christmas Day, 1776.
