2. [25 points] The following figure shows the phase diagram of Cu-Ag alloy system. A mixture of Ag and Cu with a eutectic composition (or concentration) is heated to a high temperature and keep for enough time to prepare the material into a uniform liquid state. The material is then cooled down to 800°c. Cu-Ag System 1200 Liquid 800 A 600 400 100 80 60 40 20 wt% Ag a) What is the Ag composition in the original material so...

A mixture of benzene, Napthalene, trichloroethylene and chlorobenzene were found in a groundwater plume. Consider the partitioning of these four compounds in a contaminated soil. Assume that the hydrocarbon mixture has contaminated the soil at an average of 0.09 liters of the mixture per cubic meter of soil. Considering the soil above and below the water table (ie. each cubic meter is 60% saturated with water by volume). The soil contains 0.75% organic carbon and has a porosity of 30%...
Question 14 The melting point of a pure compound is known to be 110-111º. Describe the melting behavior expected if this compound is contaminated with 5% of an impurity. 90-96 111-113 90-91 110-111 5 pts Question 15 You and your lab partner take melting points of the same sample. You observe a melting point of 101-107°C, while your partner observes a value of 110-112°C. Explain how you can get two different values with exactly the same sample. One of the...
QUESTIONS ON DISTILLATION TO BE TURNED IN Name - You were to separate a mixture containing 20 ml of hexane and 20 ml of sodium acetate. At 60°C, the total pressure of the system is 720 torr. 1. What is the mole fraction of each component? 2. Calculate the partial pressures of the components. 3. What is the vapor pressure lowering of hexane? What other two properties, entities, or functions have similar properties as vapor pressure lowering? What happens as...
Problem #1: Haber-Bosch process. The Haber-Bosch process is an equilibrium-limited catalyzed reaction that converts nitrogen (N2) and hydrogen (H2) into ammonia (NH3). The process won Haber a Nobel Prize since it provided a way to produce fertilizer for millions of people at the beginning of the 20th century. However, this process typically has very low single pass conversion due to a low equilibrium at the prevailing temperature and therefore a recycle stream is required to achieve a high overall conversion....
You have a mixture of the proteins listed below. Protein pI Molecular Weight (kDa) A 3.1 265 B 6.9 93 C 10.3 96 D 7.1 43 E 8.6 189 1. You load the protein mix onto a cation exchange column at pH 5. Next, you apply a "washing" step by passing through buffer at pH 5. Finally, for your elution step, you apply a pH gradient starting from pH 2.0 to pH 13.0. (A gradient buffer system allows you to...

what is the theoretical yield of anisalacetophenone and
dibenzalacetone formed? thank you.
The Aldol Condensation Precautions: Acetone, ethanol and acetophenone are flammable; work in a fume hood. Sodium hydroxide is a strong base and can cause severe skin burns and eye damage. Safety goggles are required. Gloves are recommended. Purpose To carry out two Aldol condensation reactions in which no heat is needed to obtain the condensation product. The two reactions differ in the number of enolizable protons at the...
