Aim: To determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring

9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation

Introduction: The purpose behind (the first step in) this experiment is to show that similarly to week 1‚ the molarity of an acid or base in solution can be determined (so long as one value’s is known) using titration. In this case though‚ finding the molarity of the acid used in the reaction is then used to determine the percent of that acid in a vinegar solution and compared to the standard value for % acid present in vinegar. The second part of the experiment was to see if by titrating a solution

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration
