Alcoholic beverages are solutions. Typically, a beer contains about 4.50% (v/v) of ethanolfermented by yeast from sugars while rum contains about 40.0% (v/v) ethanol. Meanwhile, arubbing alcohol is also an alcohol solution which contains 70.0 %(v/v) isopropyl alcohol fermentedby a bacterium instead of a yeast. Compute the mass (g) of ethanol (CH3CH2OH) in three 500.0 mL bottles of beer. Meztiza, a beer cocktail, is prepared by mixing rum, beer, and cola. Compute the finalconcentration(%w/v) of ethanol in meztiza if 100.0 mL of beer was first mixed with 5.0 mL rum andbefore finally diluting it with cola to produce 200.0 mL of the beer cocktail. Compute for the concentration of isopropyl alcohol (C3H8O) if 50.0 mL of rubbing alcohol wasdiluted to 350.0 mL with distilled water.

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?
1)The production of authentic tequila is restricted to the blue agave and a defined geographical area in west-central Mexico. Two basic categories of tequila can be distinguished: “100% agave” and “mixed” tequila. High-quality “100% agave” tequila uses pure agave juice for fermentation and Mexican law states that these authentic tequilas must be bottled in Mexico. A mixed tequila is manufactured by adding up to 49% (w/v) of sugar from sugar cane for fermentation. The low-quality tequila is usually shipped in bulk containers for diluting and bottling in the importing countries. Due to frequent fraud in the labeled quality of tequila, there is a need to verify the authenticity of a tequila using chemical analysis. Figure 1 shows an ion chromatogram for an authentic 100% agave tequila and a commercial mixed tequila. The difference in anion content is due to the different sources of water used in final dilution and bottling steps. a) In reversed-phase liquid chromatography, a…
In the production of a bottled alcoholic mudslide, 3 ingredients are mixed together and bottled: Stream A: Vodka (41.17% ethanol, the balance is water) Stream B: Coffee liqueur (17.10% ethanol, 1% coffee solids, the balance is water) Stream C: Irish cream liqueur (17.82% ethanol, 21.05% sugar, 14.05% cream fat, the balance is water) The product needs to contain 24.49% ethanol and 6.48% sugar for it to qualify as a mudslide. If your target production is 328 kg/d, how much coffee liqueur is needed?

A 25mL volumetric pipet is used to deliver a sample of the stock solution marked “0.6000M X2SO4” into a 100mL volumetric flask. Distilled water is added to the flask until it is about 3/4thfull, the solution is mixed well, then more water is added to fill it up to the calibration mark, then it is mixed again. Calculate the concentration of X+ion in the dilute solution made above.
