Priya Chauhan August 27‚ 2012 Period 3 Rainbow Lab Objectives: We should develop skills measuring chemicals with a graduated cylinder. We should practice using the metric system. We should have the ability to follow directions and to test precision. We should practice lab safety procedures. Procedures: Part 1: Label six tubes in order: A‚ B‚ C‚ D‚ E‚ and F. Fill a beaker half way with water. Use it to rinse your graduated cylinder and test tubes. The second beaker is for

Design Lab #17: Reaction Rate - Calcium Carbonate & Hydrochloric acid Design D: Introduction: In this experiment calcium carbonate will be put into a flask and mixed with hydrochloric acid to produce calcium chloride‚ water and carbon dioxide. The formula for this reaction is: CaCO3(s) + 2HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l) Purpose: The purpose of this experiment is to determine how the surface area of CaCO3(s) affects the rate of

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof

Physical Science lab #5 Objective The goal of this experiment is to develop a theory‚ which allows us to understand the motion of a marble. Materials Wooden roller coaster‚ marble‚ ruler‚ timer‚ clamp‚ physics stand. Theory In this experiment‚ we are finding the Conservation of Energy. Energy is neither created nor destroyed. Energy is summed up into two different properties: Potential energy and Kinetic energy. The law of Energy states that: Total Energy = Potential

This results in acetylsalicylic acid or "aspirin". Acetylsalicylic acid is synthesized in labs and does not occur naturally. It is produced from adding acetic anhydride to salicylic acid in the presence of sulfuric acid (H2SO4)‚ an acid catalyst: (Diagram from 1) The impurities left over (unreacted salicylic acid‚ acetic acid and sulfuric acid)
