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

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

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

Title: That immediate past experiences of being presented with either images of animals or faces influence what the subject perceives in the ambiguous figure in that if presented with animals‚ the subject would see a rat‚ and subjects shown the faces will see a man’s face. Abstract: The primary purpose of this activity was to investigate immediate past experiences and how they play a part in visual perception. The basic method involved participants being divided into three pairs to be tested

Experiment 2: Synthesis of Isoamyl Acetate (Banana Flavor) Paul Symon C. Manuel*‚ Katherine Merene‚ Charlene Mondelo‚ and Pamela Mallari Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract: The purpose 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

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

A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

RECRYSTALLIZATION Group Medical Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot 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
