The balanced chemical equations for the oxidation of Fe 2+ to Fe 3+ by dissolved oxygen and for the formation of Fe ( OH ) 3 ( s ) by reaction of Fe 3+ ( a q ) with HCO 3 − ( a q ) are to be stated. Concept introduction: Coagulation is the phenomenon by which the small destabilized particles clumped into larger aggregates so that they can easily separate from the water. The process of coagulation involves neutralization of charge. It is a useful process to remove color, turbidity and bacteria from the water. Coagulant is a substance that aggregate dissolved contaminants in water. Ferrous sulfate, aluminium sulfate are used as coagulant. To determine: The balanced chemical equations for the oxidation of Fe 2+ to Fe 3+ by dissolved oxygen and for the formation of Fe ( OH ) 3 ( s ) by reaction of Fe 3+ ( a q ) with HCO 3 − ( a q ) .

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
