Title: Competing Nucleophiles (Exp 24‚ pp 211-221‚ pp 808-823‚ pp 836-842) Purpose: The purpose of this experiment is to determine the nucleophilic strength of chloride and bromide ions as it reacts with 1-butanol (n-butyl) and 2-methyl-2-propanol (t-butyl alcohol) under SN1 and SN2 conditions. Method: 40 g of ice and approximately 30 ml of sulfuric acid is cautiously added to a 100 mL beaker respectively. Weigh 7.6 g of ammonium chloride and 14.0 g of ammonium bromide and place it in

However it is inefficient because a small amount of liquid is always left in the solid residue and very fine solid particles take some time to settle out and any disturbance of the liquid can mix them in with the liquid being poured off. Chromatography is used to separate mixtures of substances into

the different chemical properties of each compound. We will accomplish this by a separation procedure known as distillation‚ which relies on each compound having a distinct and separate boiling point. Our pure products will be analyzed with gas chromatography to determine the success of the distillation. Procedures The experiment was performed as stated in the course textbook: Pavia‚ D.

However; the following modification were made to the procedure: Use gas chromatography instead of refractive index Collect GC for only fraction 1 and fraction 3 because of time constraints.

Page 2 Europe Page 4 Conclusion Page 5 References Page 6 Summary Natural gas markets are different unlike oil‚ they are categorized under regions. This is due the fact that natural gas sources are found far away from the consumers and the cost of transportation of natural gas is high over long distances. However‚ the cost of domestic consumption is also high due to high capital required for investment. Natural gas has three main markets which are located in Europe‚ North America and Asia; with

The knowledge of chemical analysis today has become important not only for scientists in their research but in fact bears influence in our daily routine as well. To recognize and classify these uses‚ we have to first understand‚ what is chemical analysis?Chemical AnalysisChemical Analysis is a body of procedures and techniques used to identify and quantify the chemical composition of a sample of substance.1 It may be said as a collection of all the techniques required to obtain any chemical information

Box Coverts Beer Waste to Bio-Gas Cambrian Innovation has now come up with ways to easily convert beer waste into bio-gas‚ which can be used to power large scale factories‚ businesses‚ and even schools by using less energy. Matthew Silver‚ CEO of Cambrian Innovation studied bioelectric systems that could potentially be used to manage water in space‚ in doing so he saw a great opportunity to develop a certain microbe that could clean the industry’s water and make it reusable time after time.
