This research presents‚ first an explanatory abstract frame of the influence of the local context variables and the variables of programming on the recall of the placement; and second an empirical validation realized in two phases. First of all‚ a qualitative analysis of contents by experts; then a quantitative study by experimentation realized with 150 individuals. The results show that‚ globally the effect of the local context on the memorization

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

TITLE: Determination of Riboflavin by using UV-Vis spectrophotometry. ABSTRACT: The amount of Riboflavin in various brand of children multivitamins was determine by using UV-Vis spectroscopy instrument‚ the series of standard of riboflavin was prepared in order to determine the amount of the riboflavin in the sample of children multivitamins. The maximum amount of riboflavin was found in the Champs multivitamin that contains 0.1155 mg followed by Chewies 0.1131 mg and Scott’s 0.0672 mg. OBJECTIVES:

Chemistry 121 Experiment 19 Molar Mass Determination y Depression of the Freezing Point Introduction: The most commonly used liquid is water. In this experiment we study the equilibria that can exist between pure water and an aqueous solution‚ and ice‚ the solid form of water. The heat will transfer from a higher temperature to a lower temperature. In order for water to change states of matter‚ it takes a certain amount of kinetic energy or heat. The shift from ice to water (solid to a liquid)

Experiment 5 The Quantitative Determination of an Acid in Carbonated Beverages Thomas Canfield Kelly Caddell Chemistry 144B T.A. Brock Marvin 15 October 2012 Methods: Two sodas containing citric acid were investigated in this experiment. Each soda was titrated using one of the two experimental methods. These methods are the traditional titration and the modern titration. Carbonic acid was already removed from the soda by boiling it. Both of the two different titration methods

Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium
