1.1 Describe the common types of fractures There are two types of fracture called open and closed. A closed fracture is where the skin is unbroken‚ but the internal damage to surrounding tissue can be seen as swelling. An open fracture has a wound. The bone may or may not be protruding. There is also internal damage to surrounding tissue. 1.2 Describe how to manage a fracture. A casualty with a fracture needs to keep still and not move the injured part. The treatment for a closed fracture is to

Experiment 8: Synthesis of Adipic Acid Performed November 8th & 10th By Jennifer Seitz Organic Chemistry 344 Section 803 Fall 2011 Objective: The purpose of this experiment was to synthesize adipic acid from cyclohexanol via an oxidation reaction that was catalyzed by sulfuric acid. Purity of the product was assessed by measuring the melting point. Physical Properties/Structures: Name | Formula | Molecular Weight (g/mol) | Boiling Point (0C) | Melting Point(0C) | Density(g/mL)

Crystallization of Benzoic Acid Purpose: The purpose of this experiment is to purify benzoic acid by crystallization. Procedure: 1. 0.5g impure benzoic acid was placed in a 50mL Erlenmeyer flask. 15mL of water was added and the mixture was heated to a boil on a hot plate. 0.5mL of water was added to the flask‚ while swirling the flask. The mixture was boiled until the benzoic acid completely dissolved. The total volume of water used was recorded. The black solid that remain in the dissolved

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

Electrophoresis of Amino Acids Introduction: Electrophoresis is a separation technique based on the movement of charged ions under the influence of an electrical field. This technique is primarily used for the separation of amino acids and peptides on the basis of their charge. All amino acids contain ionizable groups that cause the amino acids‚ in solution‚ to act as charged polyelectrolytes that can migrate in an electric field. The amino acids with a net positive charge will migrate toward

What are its sources? Which states do you think contribute the most to it? And which states are net-recipients? What is the common budget spent on? Is it larger than a state’s budget? How does it compare? Why has the budget and its negotiation become so controversial? Current budget negotiations highlight

expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the melting point range of 152°C-154°C was recorded. After standardizing the melting device‚ a small sample of unknown carboxylic acid was placed in a capillary tube‚ and an arbitrary plateau of 200°C was set. When the sample started to melt at 150°C‚ another capillary tube containing a small amount of unknown sample was placed in the melting device‚ and the plateau was set to 135°C

footage of this experiment? Initially when I watched this experiment I felt sadden. One that is was necessary in the 70’s for this teacher to need to teach this lesson‚ but most of all how easily swayed these children were. They were so quick to demoralize their classmates‚ solely based on the fact the teacher told them they could. It is a reminder that children are most susceptible in their formative years. It also is a very important experiment as the use of children for social experiments is not

Title: Estimation of Ascorbic acid Aim: To determine the ascorbic acid content of canned apple and orange juice To determine the volume of canned juice necessary to provide 75mg of Vitamin C Introduction: For the estimation of ascorbic acid‚ the method used involved the titration of the ascorbic acid‚ in the presence of a redox indicator 2‚6-dichlorophenol-indophenol (DCPIP) which acts as both an oxidant so as to oxidise the ascorbic acid to dehydroascorbic acid‚ and it acts as an indicator
