November 15‚ 2007 Synthesis of 1-Bromobutane Introduction: The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will

Silicon Element Silicon is a chemical element with the symbol Si and atomic number 14 and atomic mass is 28. It is a tetravalent metalloid‚ less reactive than its chemical analog carbon‚ the nonmetal directly above it in the periodic table‚ but more reactive than germanium‚ the metalloid directly below it in the table. Controversy about silicon’s character dates to its discovery; it was first prepared and characterized in pure form in 1823. In 1808‚ it was given the name silicium‚ with an -ium

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

* The answer to the second question is "No". * The hydrogens are enantiotopic. * Since enantiomers have identical chemical and physical properties‚ the enantiotopic hydrogens behave identically to all achiral reagents and spectroscopies. * However‚ they would be different in any interaction in a chiral environment‚ such as with an enzyme. The center to which the enantiotopic hydrogens are attached is said to be prochiral. *

When Gustav Robert Kirchhoff’s banker questioned the financial unreliability that would result from Mr. Kirchhoff investing his hard-earned gold in Fraunhofer lines‚ Kirchhoff handed him the medal he had earned from his research and replied “Look here‚ I have succeeded at last in fetching some gold from the sun.” Despite how phenomenally sassy this quote makes him appear‚ Kirchhoff lived a quiet life (aside from his incredible scientific contributions‚ of course). Gustav Robert Kirchhoff was born

why you identified each unknown as you did. Unknown 1 was Sodium‚ as it burned with the same colored flame as the sample of Sodium‚ and Unknown 2 was Potassium‚ as it’s flame was concistent with the flame test results of Potassium. Part Two (Spectroscopy): 1. Create and complete a data table for Part Two of the lab. It should include the name of the element‚ the colors‚ and the wavelength values of the observed lines. | Hydrogen | Helium | Sodium | Neon | Mercury | 1 | purple / 413

encouraging them in recycling. The advancement of these programs –TiTech “with more than 1‚000 of which are now installed worldwide‚” can increase the efficiency of the recycling due to the fact that it is a multifunctional sorting system that uses spectroscopy to categorize trash and different recyclables; moreover‚-“Single Stream” is a system that can recover a wide range of pieces of material from different waste streams‚ household waste and other sorting tasks; Single stream recycling makes it simple

Abstract The Greek-Roman Isis temple is located on the west bank of Luxor; Upper Egypt was made of sandstone and decorated with different kinds of wall paintings. It suffers from many causes of deterioration and degradation mainly ground water‚ salt weathering‚ and different types of dirt accumulations on the relives and paint surface such as soot‚ grease‚ wax‚ biodeteriorated colored patches‚ bat patches‚ waste of birds and even house fly specks. All these lead to the gradual disappearance of paintings
