The human microbiome is one of the major frontiers of current scientific investigation. Increasing the diversity within your "gut" can be achieved by consuming probiotics from fermented foods and beverages such as sauerkraut and kefir. Kombucha is a tea co-culture of bacteria and yeast (called a SCOBY) and ethanol is one of the products of this fermentation. Lindsey regularly drank kombucha for its perceived health benefits but was concerned about her blood alcohol level. When drinking kombucha, Lindsey's maximum blood alcohol concentration (BAC) reached 0.9 mg/100mL of blood. Given that the initial half-life for ethanol in the body is 40 minutes, what will be Lindsey's BAC after one hour (60 minutes)?
2) Explain why it is common practice to determine a melting point on an unknown compound rapidly first, and then to rerun the melting point slowly.
The Dumas method was used to determine the molar mass of an unknown volatile liquid. Atmospheric pressure was 1.000 atm. Volume of flask was measured as 248 mL. Water bath was maintained at boiling temperature until liquid completely evaporated. Then the flask was cooled down. Mass of condensed vapor was determined as 0.4704 g. The liquid is likely to be: (A) Acetone, (CH3)2CO (B) Isopropanol C3H7OH (C) Diethyl ether (C2H5)2O (D) Isooactane C8H18
Please answer the question at the bottom. Fractional distillation Measure 55 mL of 40% ethanol Place 50 mL of ethanol in your distilling flask taking care that no liquid enters the side arm. Place the remaining 5 mL of ethanol in a test tube and set aside for procedure 2. Add a few marble or porcelain chips to the distilling flask to prevent bumping. Bumping is a term given to irregular boiling Assemble the rest of the apparatus for a simple distillation set-up. You may ask assistance from your instructor Cover the top of the distilling flask with a cork fitted with a thermometer. Make sure that the tip of the thermometer bulb is just below the side arm of the distillation flask Check all connections for tightness Heat the contents of the flask to boiling. Adjust the flame when the sample is already boiling. Make sure that it does not boil to dryness. Note the temperature of the first drop. Collect 60 drops of distillate per test tube. You will need 5 test tubes, thus five…
