What fraction of TCE is in aqueous phase and sorbed phase of the soil?A binary mixture with components A and B is to be separated in a distillation column to obtain 95 mol%. A as the top product. The binary mixture has a con stant relative volatility AB = 2. The column feed is a a - saturated liquid containing 50 mol % of A. Under the usual simplifying assumptions such as constant molal overflow, negligible heat loss, ideal trays, the mini mum reflux ratio for this separation is (rounded off to one decimal place)

MW=36.5An environmental study was performed to measure the transport of a DDT (a banned pesticide) throughout the globe. A lake in northern Canada was sampled to see if low levels of DDT were present there in spite of it not being administered within 1000 miles of that location. 1.000 L of the lake water was spiked with 100.0 uL of a 2.451 ug/L solution of tetrachlorobenzene, which acted as the internal standard. The entire 1.000 L spiked solution was concentrated onto an SPE column. After washing the SPE column with ~5 mL of pure water, the analyte and internal standard were eluted from the SPE column using ~5 mL of CH2Cl2 solvent. The eluted sample was evaporated under a stream of nitrogen to a final volume of 1.000 mL. 1 uL of this final solution was analyzed using GC-MS, and gave a signal of 24835 for DDT and 11597 for tetrachlorobenzene. To calculate the response factor, a standard solution was prepared consisting of 1.482 ug/L of DDT and 2.451 ug/L of tetrachlorobenzene.…

Particularly #5 should be useful: A linear fit of the data in the chart yields the equation y = (-5.0020x10^3)x+(2.100x10^1) with an R2 value of 0.9922. Determine the enthalpy (deltaH in kJ) associated with dissolving KNO3. Answer in scientific notation with appropriate sigfigs.A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.A 100 g soil containing 20% smectitie mineral matter was mixed with 150 mL solution containing 0.10 M Pb.
