TENS 2146 Electric Devices and Measurements Lab 3 Current and Voltage This report was prepared by: L. Wall Fall 2009 Prof. R. Alba-Flores Team Members: J. White‚ L. Wall Conducted on: September 17‚ 2009 Submitted on : September 24‚ 2009 Abstract: In this lab students experimented with light emitting diodes. The student built a basic circuit with two LED’s and resistors in parallel. The results showed that the voltage is the same in parallel. The items that were in series had the

Cleveland‚ OH. November 30‚ 2012 Summary The purpose of this report is to determine why we should lease computer equipment as opposed to purchasing computer equipment. Leasing computers can save this organization revenue by not having to have an on-site IT Department for any hardware or software issues that develop. Any technological advances that develop can be upgraded to stay current with technology. This report will also look at the total cost of ownership as compared to leasing computer

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

Ragpa Group 8 2B Medical Technology Organic Chemistry Laboratory ABSTRACT The main objectives were to separate the colored components of malunggay leaves by means of column chromatography‚ as well as to determine the purity of the components using thin layer chromatography (TLC) and measure the Rf values of the colored components obtained herein. For column chromatography‚ the sample prepared was loaded into a Pasteur pipette plugged with cotton and uniformly packed with silica gel. The eluents

Purification of Acetanilide by Recrystallization Method Dupaya‚ Julian Victor M. Estacio‚ Jerwin Caesar A. Farnacio‚ Rebecca Ruth Gabito‚ Jose Luis F. Gallo‚ Cian Carlo M. Galvez‚ Joshua M. Group no.4‚ 2D-Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Recrystallization is a method for purifying solid organic compounds. The process is dissolving the solid to be purified in a hot solvent and cooling the solution slowly‚ this allows impurities with different

of this experiment was to synthesize isoamyl acetate via an esterification reaction between acetic acid and isoamyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water‚ and then dried with anhydrous sodium sulfate. The percent yield of isoamyl acetate was 52.79%. The product was isolated using a combination of techniques – acid-base extraction‚ drying‚ and in special cases distillation. Introduction: The importance

RECRYSTALLIZATION OF ACETANILIDE De Ocampo‚ Yves Aaron Julian Q.‚ Dela Vega‚ Roderick B. Jr.‚ Elguira‚ Cedric Tristan D. Enriquez‚ Joanne B.‚ Gabat‚ John Elliot N. Group 5 2D-Medical Technology Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT The experiment was executed in order to purify compounds through recrystallization. Recrystallization is the primary used operation for purifying solid organic compounds that differ in solubility at different temperature. It is a process of dissolving

solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride‚ was used as the pure organic compound. Crude acetanilide underwent crystallization process using the preferred recrystallizing solvent‚ water. The crystallization process was when crude acetanilide was placed in hot water bath and was cooled after in an ice bath which would then yield to the formation of crystals of pure acetanilide.
