Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

Abstract This report is to highlight the methods‚ results and theory relevant during an engineering experiment called “cold rolling of metals". The purpose of this report is to show how readings obtained from the set-out experiment‚ can be evaluated to determine the behavior of 3 selected materials; Brass‚ Copper and Aluminium through the process of cold rolling. The form of the materials are in small strips which are processed via cold-rolling method 4 times from their original state to evaluate

ABSTRACT: the purpose of the experiment was to find out how double displacement happened. When the chemicals and metals were mixed the product was white and the test tube turned very hot. INTRODUCTION: the purpose of this experiment was to identify double displacement and why is happened. Based on background information the chemicals when combined will fizz and turn very hot. Also‚ the chemicals used in this experiment are potentially harmful‚ so make sure to use goggles and tonsils to hold the test

of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For calcium‚ the gas

Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above
