Define a slag and describe the role that it plays during the commercial production of iron. Concept introduction: Extracting a metal from 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 Metal-oxides will undergo reduction with carbon, hydrogen, or a more active metal. The most active metals must be reduced by the process of electrolysis . A blast furnace is used in the production of commercial iron which extracts iron from iron ore. To classify: Slag and its role in iron production.

You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: xi 1. ☑ 2. H₂O хе i Draw the missing reagent X you think will make this synthesis work in the drawing area below. If there is no reagent that will make your desired product in good yield or without complications, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. There is no reagent that will make this synthesis work without complications. : ☐ S ☐

Predict the major products of this organic reaction: H OH 1. LiAlH4 2. H₂O ? Note: be sure you use dash and wedge bonds when necessary, for example to distinguish between major products with different stereochemistry. Click and drag to start drawing a structure. G C टे

For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 CI MgCl ? Will the first product that forms in this reaction create a new CC bond? Yes No MgBr ? Will the first product that forms in this reaction create a new CC bond? Yes No G टे
