hree components in a mixture have varying distribution constants between the mobile phase and the stationary phass One of the components has a very low distribution constant, Would this component likely elute first or last and how would you design an experiment or modify the components of the separation to make it perform in the opposite manner?
Which statements are true for molecular exclusion chromatography?I Molecular exclusion chromatography separates on the basis of size.II Small molecules can fit in the pores of the stationary phase and effectively pass through a larger volume, and elute last.III The pores in the stationary phase are too small for large molecules to pass through, so large molecules elute first.IV Molecular exclusion chromatography with a hydrophilic stationary phase and an aqueous solvent is called gel permeation chromatography.

The soxhlet extraction method was applied to a solid food sample that matrix effects are expected to be significant for the total lipid analysis. The sample was directly subjective for extraction, and ethanol was used as the extraction solvent. (a.) Outline the typical procedure of the Soxhlet extraction method (b.) Calculate the per cent lipid of the food sample if the result is as following: -Food sample: 12.5755 g -Initial weight of the solvent flask: 30.5697 g -Weight of the solvent flask treated with the ethanol: 30.6271 g -Weight of the solvent flask treated with the sample: 34.0293 g (c.) The value of total lipid content obtained from (b) was much lower than that expected. Suggest three possible reasons and the respective modification improve the analysis.

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…
