Using the standard reduction potential for zinc and magnesium, explain why zinc can be reduced with coke while magnesium cannot be reduced using this process. Concept introduction: An ore is a complex mixture of metal-containing mineral and economically worthless material called gangue, consisting of sand, clay, and other impurities. Extracting a metal from its ore requires three main steps: (1) concentration of the ore, and if necessary, chemical treatment prior to reduction; (2) reduction of the mineral to the free metal; (3) refining or purification of the metal. Roasting is the process of heating the sulfide minerals in air (O 2 ) to form metal-oxides To classify: Why zinc can be and magnesium cannotbe reduced with coke.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
