Liquid Crystal Display A liquid crystal display (LCD) is a flat panel display‚ electronic visual display‚ or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden‚ such as preset words‚ digits‚ and 7-segment displays as in a digital clock. They use the same basic technology‚ except that arbitrary

Reuven Ilyayev Lab Instructor: Maciej Domaradzki Labs 3 & 4 09/19/11 Objective: In steam distillation lab (lab 3)‚ we must obtain pure Eugenol from cloves through the process of steam distillation. In the crystallization lab (lab 4) part 1‚ we must acquire the best possible pure crystallization of acetylsalicylic acid from aspirin and in part 2 we must obtain a similar pure crystallization of benzil from an impure mixture of benzil. Materials: In lab 3‚ we used 75 g of cloves from

Acetaminophen Abstract: The aim of this experiment is to prepare Acetaminophen (p-acetamidophenol)‚ an amide. Acetaminophen will be created by treating an amine (p-aminophenol) with an acetic anhydride. Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to

PR OCEDURE Before beginning‚ set up a data table similar to the Data Table: Experiment Results in the Lab Report Assistant section. This experiment will create a reaction of sodium carbonate and calcium chloride dihydrate to produce a precipitate of calcium carbonate. This formula is: Na2CO3(aq) + CaCl2. 2H2O(aq) à CaCO3(s) + 2NaCl(aq) + 2H2O 1. Put on your goggles. 2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium

THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the substance

Do all liquids evaporate? What would happen if liquids never evaporated? Do we know which liquid evaporates the fastest? Could we perhaps use this knowledge to change the everyday processes? The process of evaporation happens much differently than scientists once thought. Every liquid eventually evaporates and often what remains is the solid particles which were once part of the solution. Evaporation is very important: “it shapes the climate of the planet‚ it affects the cost of car travel
