Determination of an Electrochemical Series In electrochemistry‚ a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an easily measured electrical potential which has a positive value. Voltaic cells have a variety of uses and you commonly refer to them as a “battery”. Half-cells are normally produced by placing a piece of metal into a solution containing a cation of the metal (e.g.‚ Cu metal in a solution

ABSTRACT A molecular diffusion experiment was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment‚ acetone was placed in a capillary tube and was allowed to diffuse into non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular

total of three calf measurements on the same person‚ then the average of theses three measurements were taken. Next a caliper was used to account for the fat to muscle ratio and again each group member measured with the caliper on the medal side of the calf for a total of three measurements‚ then the average was taken. The average of the calf circumference minus the average of the caliper measurements‚ became the adjusted mean for the leg circumference (BIOPAC systems ‚ 2010). Then group members were

Abstract: Enthalpy of vaporization of ethanol was determined by measuring change in temperature and pressure of ethanol using a Vernier temperature probe. By using the ideal gas equation‚ and plugging the slope value from the graph into the Clausius-Claypernon equation‚ enthalpy of vaporization was determined to be 10kJ/mol. The percent error was determined to be 76.0%. Introduction: The purpose of this lab is to investigate vapor pressures and the partial pressure of gas produced from liquids

EXPERIMENT 1: THE EFFECTS OF PACKAGING MATEIAL ON SHELF LIFE OF CRACKERS Introduction The type of food‚ chemical composition‚ size‚ storage conditions‚ expected shelf life‚ moisture content‚ aroma and appearance are just a few of the characteristics that must be taken into consideration when selecting the right material for a food product. A continuing trend in food packaging is the design of packages to extend the shelf life of foods while maintaining fresh-like quality. This places a high demand

There are many methods to know someone’s body composition and body fat percentage such as measurement with calipers‚ underwater body‚ fat test‚ the bodpod‚ DEXA scan and bioelectrical impedance analysis. (Kravitz‚ Len‚ Ph.D. & H. Heyward‚ Vivian‚ Ph.D.). The calipers method involves measuring the skinfold thickness of the layer of fat just under the skin in several parts of the body with calipers. The results are then calculated and the percentage of body fat is determined. Underwater weighing is
