If you were to analyze your distillate by GC, you might notice a trace amount (<0.05%) of methanol. However, methanol can be oxidized into formaldehyde, which is quite toxic. This is why moonshine was traditionally unsafe to drink during the unregulated prohibition period. How could you revise the procedure of your distillation to try and limit the isolation of methanol-laced ethanol?

Using the provided ternary phase diagram 1. What is the number of phases in this liquid mixture? Liquid Amount || Amount (mol) A || 15 B || 20 C || 7.5 xT || xW || xE 0.5 || 0.25 || 0.25 0.33 ||0.33 || 0.33 0.1 || 0.8 || 0.2 2. What are the phase compositions of the mixtures in Problem 1? What are the trichloromethane-rich and water-rich phases' compositions if there are two phases?

5. With reference to the Cu-Zr binary phase diagram below, answer the following questions: a) What is the maximum amount of copper than can dissolve in aZr at 846°C (by atomic%). Calculate the equivalent weight% at this overall composition (you will need to find the atomic weights of both elements). b) What happens if more copper is added after this solubility limit is reached? c) What is the highest temperature eutectic in this system (temperature and composition)? d) Identify a eutectoid point in this diagram using an arrow. e) What happens to CusZr if it is cooled slowly from 700°C to room temperature?

The phosphorus in a 0.2385-gram sample was precipitated as the slightly soluble (NH4)3PO4.12MoO3. This precipitate was filtered, washed and then redissolved in acid. Treatment of the resulting solution with an excess of Pb+2 resulted in the formation of 1.6725 gram of PbMoO4. Express the results of the analysis in terms of % P2O5. Molar Masses: PbMoO4 (367.14) and P2O5 (141.94)

Calculate the solubility of Zn(OH)2 in a 0.0300M K2SO4 solution using activities and concentration. Determine the % error when using only concentrations (assuming that the actual solubility is the determined with the activity). The Kps of Zn(OH)2 is 1.2 x 10-17

The rate constant for the second-order reaction: 2NOBr(g) 2NO(g) + Br₂ (g) is 0.80 at 10.0 °C. Starting with a concentration of 0.86 M, calculate the concentration (in M) of NOBr after 51 s. Round your answer to 2 significant digits. (M-s) M X $

2. The Orsat analysis (% mol and water-free basis) of combustion gases is as follows: 0.99 % CO, 1.99 % H2, 6.36% 02 and 81.71% N2. If the partial pressure of water is 76 mmHg and the total pressure of the combustion gases is 760 mmHg: a. What is the mass fraction of all the components in a water-free basis? b. What is the mole fraction of all the components including water? c. What is the average molecular weight of the gases?

2. . Ethylene oxide (C₂H4O) is a high-volume chemical intermediate that is used in the manufacture of textiles, detergents, polyurethane foam, antifreeze, solvents, medicinal, adhesives, and other products like glycol and polyethylene glycol. Ethylene oxide is produced by the partial oxidation of ethylene (C₂H4) using a solid catalyst in a fixed-bed reactor: C₂H4 + O2 →→ C₂H4O An undesired reaction occurs where a portion of the ethylene reacts completely to form CO2 and H₂O: C₂H4 + O2- → CO₂ + H₂O The product gas leaving a fixed-bed ethylene oxide reactor has the following water-free composition: 22.5% C₂H4O; 70.7% N₂; 2.5% O₂; and 4.3% CO₂. Using molecular species balance, determine: a. the percent excess air based on the desired reaction b. the kg/h of the ethylene feed required to produce 75,000 MT/year of ethylene oxide c. the percent conversion of ethylene based on the desired reaction
