LABORATORY REPORT 4 PREPARATION OF ALUM FROM ALUMINUM METAL Huy Nguyen October 2nd‚ 2012 The objective of the laboratory is to synthesize alum (KAl(SO4)2.xH2O) from aluminum powder and to determine the proportion of water in the alum crystals. Alum is a product from the reaction between potassium hydroxide and sulfuric acid. The reaction include several steps‚ as followed: Aluminum powder reacts with potassium hydroxide to generate Al(OH)4- ions and release hydrogen. 2 Al(s) + 2 KOH(aq)

Preparation and SN1 Reactivity of 2-Bromobutane Whitney Bellido Department of Chemistry‚ Illinois State University‚ Normal‚ IL 61790-4160 Submitted: April 4th‚ 2013 Introduction The overall goal of this experiment is to understand and be familiar of SN1 reactivity. We also learned how to prepare 2-Bromobutane by learning how to distill and extract this product from its organic layer. Finally‚ another goal was to specifically understand the relative reactivity of alkyl halides under SN1 conditions

no single work of literature in the world‚ where a full‚ completed characterization of a person would be‚ no matter if he/she is the main character‚ or does not play any role in the novel at all. The main idea is to develop an image of a character through actions of others‚ and as it gets more complicated‚ the greater novel becomes. In Fitzgerald’s “The Great Gatsby” the author uses the technique of indirect characterization to make the reader feel the atmosphere of the society of the nineteen-twenties

Alice Walker’s “Everyday Use” is a short story that explores the way

Discussion and Conclusion: Preparation of 1-Bromobutane The purpose of this experiment was to demonstrate the conversion of a primary alcohol‚ 1-butanol‚ to a primary bromoalkane‚ 1-bromobutane‚ a SN2 reaction. The conversion of 1-butanol to 1-bromobutane relies on sulfuric acid which plays two important roles. First‚ it protonates the alcohol of 1-butanol to form an oxonium ion which is a good leaving group. Secondly‚ it produces the hydrobromic acid‚ the nucleophile‚ which attacks 1-butanol

To most effectively convey his message‚Bradbury uses characterization and irony to shape the theme that the society that we live in today is very violent and it changes people. In the book Fahrenheit 451 by ray bradbury‚ a society very different from ours burns book and totally revolves around the burning of books and technology too.Ray Bradbury uses his craft‚ literary devices‚ and literary elements to shape the themes of Fahrenheit 451 by the characters changing in very different ways throughout

he dedicates over twenty pages just to characterization of the story tellers. Chaucer takes about a page to deeply introduce the reader to each character who tells their own fable. It has been said of Chaucer’s characterization that "the sheer variety of wealth of detail creates the impression of a specific person. And yet‚ taken together‚ it all adds up to a comparatively simple stereotype" (Prompt)
