Point of view always influences the way readers perceive events. In literature‚ the point of view the author chooses not only affects the way readers perceive and interpret events‚ but it also determines‚ to some extent‚ what the readers can actually see. That is‚ point of view guides the way readers interpret events and draw conclusions by limiting or illuminating the amount and nature of the information from which conclusions can be drawn. In "Souls Belated‚" Edith Wharton uses point of view to

The Purity and Purification of Solids- Part 2- Recrystallization Courtney Percival CH 337 Laboratory‚ Section 037 Department of Chemistry Portland State University‚ Portland OR ABSTRACT INTRODUCTION Recrystallization is a commonly used tool in laboratories when dealing with impure solids. "An effective recrystallization is one in which 1) a high degree of purity is achieved as well as 2) a maximum recovery of sample".1 Solubility‚ the tendency of a substance to dissolve in a liquid‚ is an

How do different liquids and solids affect the boiling and freezing point of water? Name 02/12/12 ABSTRACT There are many different substances that affect the freezing and boiling points of water. This experiment was designed to test the effects of five liquid and five solid substances/mixtures on the freezing and boiling points of water. It was hypothesized that if we tested five liquid and five solid substances/mixtures then the results would show that the solids would have a greater affect

Those samples were analyzed

Summary Purpose To purify the component (unknown) of Pancetin from last experiment and then compare its melt point to the two other possible substances. Theory Panacetin should be made up of about 50 percent of the unknown component that we previously separated out of Panacetin for testing. We suspect that this unknown compound is either acetanilide or phenacetin. From the solubility of acetaminophen and phenacetin‚ we could know both of them are relatively soluble in boiling water but insoluble
