Experiencing Salvation in As I Lay Dying ENGLISH 215 October 31‚ 2011 William Faulkner’s As I Lay Dying centers on the absurd journey that the Bundren family takes to Jefferson to bury their dead mother‚ Addie. Faulkner frames this journey through the lens of various narrators with a specific focus on the characters’ innermost thoughts and deep interior monologues. Although the novel’s plot revolves around the Bundren family‚ characters outside of the family are essential to provide an objective

Discussion: The two dyes identified were disperse blue 3 and disperse red 9. Disperse red 9 separated first because it is less polar than disperse blue 3. This is due to the structure of disperse red 9 being more symmetrical than that of disperse blue 3 and having more nonpolar bonds. Disperse blue 3 is more polar because it has a hydroxide bond and has a larger dipole. The principle behind using column chromatography is that it separates compounds based on polarity. The alumina serves to allow

Column Chromatography ________________________________________________ You have already performed two chromatography experiments: gas chromatography and thin layer chromatography. All chromatography experiments involve passing a mixture of analytes through a system that includes a mobile phase and a stationary phase. The partitioning of the analytes between these two phases determines the rate at which they pass through the system‚ and (in theory) allows them to be separated from one another. Column
