Answer the following:

1: a) . Breathalyzers determine the alcohol content in a person’s breath by a redox reaction using dichromate ions (the unbalanced reaction is shown below). C2H5OH + Cr2O7 2− → CH3CO2H + Cr3+ a. Determine the number of electrons transferred in this redox reaction. b. Determine the concentration (in M) of Cr3+ in 50.0mL of solution at half the Canadian legal blood alcohol concentration limit (BAC, limit is 0.08 mg/mL).

b) The Keq for the reaction between strontium metal and titanium ions (shown below) is 4.0x1042. Calculate Eo for a strontium-titanium battery. Sr(s) + Ti2+(aq) ⇌ Sr2+(aq) + Ti(s)

A breath analyzer is used by the police to estimate blood alcohol content (BAC) from a breath sample. If a person’s BAC is above (or equal to) the legal limit, they can be arrested for suspicion of driving while impaired from alcohol. However, the only way to accurately measure BAC level is through taking a blood sample; a number of factors are known to influence the results of breath analyzers, such as hypoglycemia. A particular brand of breath analyzer is...

2. The following data on distilled alcohol content (%) for a sample of 35 port wines was extracted from the article “A Method for the Estimation of Alcohol in Fortified Wines Using Hydrometer Baumé and Refractometer Brix” (Amer. J. Enol. Vitic., 2006: 486–490). Each value is an average of two duplicate measurements. 16.35 18.85 16.20 17.75 19.58 17.73 22.75 23.78 9.12 10.22 23.25 19.08 19.62 33.05 19.20 20.05 17.85 19.17 19.48 20.00 19.97 42.13 11.42 03.28 41.56 17.48 17.15 19.07...

A sample of wine was diluted 1:10 and analyzed for alcohol content. A calibration curve was created from a set of standard solutions producing a plot of absorbance vs. percent alcohol. The calibration curve had a slope of 8.07 x 10-2 with an intercept of 6.02 x 10-3. Keeping in mind that the wine sample was diluted by a factor of ten, what is the percent, by volume, of alcohol in your sample if the absorbance of your sample was...

Beer and Blood Alcohol Content The relationship between number of beers consumed (x) and blood alcohol content ( y) was studied in 25 male college students by using simple linear regression. The estimated blood alcohol content ( ŷ ) is given in the following regression equation: ŷ = -0.0127 + 0.0180x Suppose that the legal blood alcohol content limit for driving is 0.05. If John consumed 4 beers the model would predict that he would be: Select one: a. 0.0027...

One method for measuring the alcohol content of a liquid is to titrate the ethanol (C2H5OH) with chromate (CrO4^2-). These reagents react to become Co2 and Cr^+3 respectively. Write the balanced equation for this redoc process under acidic conditions. If a 1.86g sample of an alcoholic beverage is titrated with 25.93 mL of 0.250 M sodium chromate, what is the percent by mass of alcohol in this beverage?
