-1Determination of an Unknown Liquid (2-butanol) Through Fundamental Analysis Lee Billips Department of Chemistry‚ Shippensburg University‚ 1871 Old Main Drive. Shippensburg‚ PA‚ 17257. Abstract: The identification and characterization of unknowns are an important part of organic chemistry. It is fundamental to know experimental methods to deductively identify compounds (1) . The determination of unknown #6 (2-butanol) was identified by a series of test; first taking the boiling point (94-96

A Discussion of Banking-Concept Limitations What do students obtain through education? Freire in his essay ‘The Banking Concept of Education’ argues that students gain useless and meaningless knowledge through education‚ and I agree with Freire because education has become an act of depositing meaningless information into students. Freire believes the current educational system is flawed due to the “Banking Concept”‚ which Freire describes as‚ “an act of depositing‚ in which the students are the

attached to the nitrogen atom and adding the word amine. In the IUPAC System‚ apply the following rules to name amines: 1. Pick out the longest continuous chain of carbon atoms. The parent name comes from the alkane of the same number of carbons. 2. Change the -e of the alkane to “amine.” 3. Locate and name any substituents‚ keeping in mind that the chain is numbered away from the amine group. Substituents‚ which are attached to the nitrogen atom instead of the carbon of the chain‚ are designated

(Author’s name) (Professor’s name) (Course details) (Date Abstract The aim of the lab was to separate and analyse analgesic drugs in a drug tablet. The method used to separate the components was Thin Layer Chromatography (TLC) with silica adsorbent as the stationary phase and 0.5% glacial acetic as the mobile phase. In one plate‚ five known samples were used as the reference‚ that is: Aspirin; Caffeine; Ibuprofen; and Salicylamide. Aspirin and Salicylamide were the only samples that fluoresced

Chirality of Ethyl-3-hydroxybutanoate Generated from a Biological Pathway Jake Zimny LaSalle University Philadelphia‚ PA 19141 Submitted February 10‚ 2006 Abstract: The reaction being studied is a reduction of a ketone into an alcohol with a chiral center. Because a biological agent‚ bakers ’ yeast‚ is being used to drive this reaction‚ the optical purity that results in the product is so stereo-selective that the major product‚ (+)‚ is formed for 89% of the product.
