Substitution Reactions of 3-phenyl-1-phenol‚ 2-pentanol‚ and 2‚4-dimethyl-3-pentanol Samantha Sparks‚ Isi Nosegbe and Sabrina Becker. Department of Chemistry‚ IUPUI‚ 402 N. Blackford St.‚ Indianapolis‚ IN 46202 This project was collaborated on by three different organic chemistry students‚ who individually synthesized and researched each of the three substitution reactions in this experiment.. The first reaction was an Sn2 reaction of 3-phenyl-1-propanol with NaBr and H2SO4 to create1-bromo-3-phenylpropane

March 18‚ 2012 Title: Types of Chemical Reactions Data: Reaction Observations Evidence #1 It turned a reddish brown and the liquid went clear. The color change proved it was a chemical change. #2 The reaction turned yellow and it separated and created a fog. The solid formed precipitation and had a color change during the reaction proving it to be a chemical change. #3 There was green smoke and the crystals turned black. The green liquid turned dark green and continued to sizzle with

Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is no reaction. Also‚

If pH > pI‚ then the protein will have a negative charge and if pH < pI‚ the protein will have a positive charge. Buffer I has a pH >5‚ meaning both proteins carry a negative charge and bind to the DEAE (a positively charged resin). (b) pH = pKa + log10(Base/Acid) [Base = mM of sodium acetate; Acid = mM of acetic acid] = 4.7 + log10 (40/40) = 4.7 In order for the catalase to elute from the column‚ it must have lost its negative charge and stopped binding to the DEAE. Lowering the pH

Title: The affects of hydrogen peroxide on catalase reactions in animal and plant cells at different temperatures and states. Introduction: All living organisms in the kingdoms of life are composed of and depend on cells to function normally. Not all cells‚ however‚ are alike. There are two primary types of cells: eukaryotic and prokaryotic cells. Cells contain organelles‚ or tiny cellular structures‚ that carry out specific functions necessary for normal cellular operation. (Regina Bailey Updated

Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can
