Calculate the vapor pressure of propanol (b.p. 97.0 ∘C97.0 ∘C) at the gas chromatography column temperature of 95.0 ∘C95.0 ∘C using the form of the Clausius–Clapeyron equation shown ln(?1?2)=−(Δ?vap?)(1?1−1?2)ln(P1P2)=−(ΔHvapR)(1T1−1T2) where ?R is the ideal gas constant, Δ?vapΔHvap is the enthalpy of vaporization, ?1T1 and ?2T2 are two different temperatures, and ?1P1 and ?2P2 are the vapor pressures at the respective temperatures. The enthalpy of vaporization can be estimated using Trouton's rule, Δ?∘vap=(88 J·mol−1⋅K−1)×?bp.ΔHvap∘=(88 J·mol−1⋅K−1)×Tbp. ?=P= TorrTorr Calculate the vapor pressure of pentane (b.p. 36.0 ∘C36.0 ∘C) at the same column temperature. ?=P= TorrTorr For compounds of the same chemical class, what is the relationship between vapor pressure of a compound and retention in gas chromatography? As the vapor pressure decreases, retention time decreases. As the vapor pressure increases, retention time increases. As…
How would you prepare 75 mL of an H2SO4 solution at 20% in weight (density=1.1394 g/mL, richness=227.9 g/L) starting from the commercial H2SO4 solution (98%, density=1.8361 g/mL, richness=1799 g/L)? Please choose among the most appropriate procedure which better describes the preparation of the previous diluted H2SO4 solution: Select one or more: a. Take the required volume of commercial H2SO4 solution with an adequate pipette, pour it into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. b. Take a beaker and put about 40 mL of distilled water. Then take the required volume of commercial H2SO4 solution with an adequate pipette and pour them over the beaker. Let the solution be warm and pour the mixture into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. c.

Louie performed paper chromatography to identify which among the four availablereference mixtures — WAR, OFF, YIN, MEW — have the same components as hisunknown sample, GUN. He spotted the standards and the sample in a Whatman No. 1filter paper, which he placed in a developing chamber containing 3% KCl. After 20minutes, Louie obtained the chromatogram below, immediately noting that the distancetravelled by the solvent from the origin is 79.0 mm. On the other hand, the distances (incm) traveled by the developed spots were tabulated as follows.(see attached) Questions: 1. Is the type of paper chromatography performed normal or reversed? Why?2. Calculate the Rf of the spots from the samples. Report your answers in four decimal places.
10g coffee 4g sodium carbonate 40m dichloromethane 160ml distilled water coffee filter What are the principles behind caffeine being extracted from coffee using the above items? 1st sodium carbonate mixed with coffee then brought to a boil for 20min then solution/grinds are filtered. Then solution is added to a separatory funnel with 15ml of dichloromethane and two layers are observed so the bottom layer with DCM contains the caffeine, then this layer is collected in a beaker and dried out using molecular seeds. Then the solvent is brought to a boil with crude caffeine remaining and recystallized using 95% ethanol and brought to a boil again. Then the contents are vaccum filtered and allowed to dry resulting in 30mg caffeine.

Oral rehydration salts are stated to contain the following components: Sodium Chloride 3.5g Potassium Chloride 1.5g Sodium Citrate 2.9g Anhydrous Glucose 20.0g 8.342 g of oral rehydration salts are dissolved in 500 ml of water. 5 ml of the solution is diluted to 100 ml and then 5 ml is taken from the diluted sample and is diluted to 100 ml. The sodium content of the sample is then determined by flame photometry. The sodium salts used to prepare the mixture were: Trisodium citrate hydrate (C6H5Na3O7, 2H2O) MW 294.1 and sodium chloride (NaCl) NW 58.5. Atomic weight of Na = 23. The content of Na in the diluted sample was determined to be 0.3210 mg/100 ml. Determine the % of stated content of Na in the sample. The stated should be 104.5, how??
