6. A 3.0 g piece of brain from a victim of fatal motor vehicle crash was cut into small pieces and transferred to a headspace vial. A 20-μL aliquot of an aqueous solution of ethanol having a concentration of 1.10 mg/mL was used as an external vapor standard. It contained 12.14 ug of ethanol. Equilibration of both the sample and standard solution was carried out at 60oC for 20 minutes. The analytical results were as follows: Sample Calibration Standard A1 = 167,900 Astd = 72,550 1 – e-q = 0.4826 1 – e-q = 0.3785 Calculate the amount of ethanol in the victim’s brain.
Human saliva contains the enzyme α-amylase which hydrolyzes polysaccharide acetal linkages. A soda cracker (containing starch) was carefully ground; the crumbs were distributed evenly between two test tubes. The first test tube contained only water, while the second contained a 1% solution of α-amylase. Both mixtures were heated to 35°C for 10 minutes and filtered. The filtrates were tested with iodine solution and Benedict’s solution. Use the following results to answer the questions below. Mixture Iodine test Benedict’s Test cracker in water dark blue blue cracker in water and α-amylase red red-orange precipitate a. Was the starch from the cracker/water mixture hydrolyzed? Was the starch from the cracker in the 1% α-amylase solution hydrolyzed? b. Which cracker contained reducing sugars?
Gypsum (CaSO4) is a common percipitant in water desalination. CaSO4 <=> Ca2+ + SO42- where Ksp=10-4.6. Assuming that: [Ca2+]=2x10-2 M; [SO42-]=2x10-3M: a) Find Qsp or IAP for the given water b) Find the solubility index (SI) and determine whether CaSO4 is under, super, or at saturation in water. Feel free to make any assumptions you wish, as long as they're stated.

Based on the dissolved solute's properties, we can quantify that solute's concentration are too high to permit an accurate measurement. For example, a spectrophotometer can measure the amount of light that passes through a sample solution for If the solute's concentration is too high, a relatively small amount of incident light having the wavelength that corresponds to the solute's absorption behavior will less light is absorbed, and the detector in the spectrophotometer can generate more reliable data. reach the dete ctor, which results in an inaccurate measurement (consider the result if you blocked the light with an opaque…
