Acid-Base Balance and Fluids and Electrolytes Student’s Name Institutional Affiliation Date Due Respiratory Acidosis Respiratory acidosis refers to a medical defect in which hypoventilation occurs leading to increased concentration of carbon dioxide in the blood and decreased level of pH. Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar

Abstract The purpose of this experiment was to perform a liquid-liquid extraction method to extract the caffeine from the tea bags that were provided‚ and then recrystallize the caffeine. The solvents used in the experiment were an aqueous sodium carbonate and dichloromethane (DCM). Anhydrous calcium chloride pellets were used to dry the solution and emulsion layer and the DCM was then decanted. After washing the anhydrous calcium chloride pellets with more DCM‚ the solvent was evaporated‚ leaving

Procedure 2: DNA Extraction from Cheek Cells Materials: Water‚ Clear Dish Soap‚ Table Salt‚ Isopropyl Alcohol (70%) or Ethanol‚ Food Coloring 1. To 200 Ml drinking water add two teaspoons of salt 2. Gargle the salt water for 1 minute. 3. Spit the gargled water into a beaker (or new cup). Now your cheek cells are suspended in the salt water. 4. Gently stir the salt water with one drop of soap (try to avoid air bubbles) 5. In a separate beaker (or cup)‚ mix 20 ml isopropyl alcohol and 1-3 drops

City University London Fluid Flow in a Duct of Varying Cross-Section Report: Khurshidanjum Pathan‚ Group A1a Abstract: The experiment is carried out to demonstrate the relation between pressure and fluid velocity in a duct of varying cross-section by using Bernoulli’s equation and continuity equation.(1) Bernoulli’s equation relates the pressure to the velocity for a fluid of constant density flowing in a Venturi tube. Static head‚ normalised head and percentage of errors were calculated using

Chapter 6 Momentum Analysis of Flow Systems Chapter 6 MOMENTUM ANALYSIS OF FLOW SYSTEMS Newton’s Laws and Conservation of Momentum 6-1C Newton’s first law states that “a body at rest remains at rest‚ and a body in motion remains in motion at the same velocity in a straight path when the net force acting on it is zero.” Therefore‚ a body tends to preserve its state or inertia. Newton’s second law states that “the acceleration of a body is proportional to the net force acting on it and is inversely

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

We wanted to extract‚ see and analyze DNA from a single strawberry( 12.11 g). The long‚ thick fibers of DNA store the information for the functioning of the chemistry of life. DNA is present in every cell of plants and animals. The DNA found in strawberry cells can be extracted using common‚ everyday materials. To start the procedure we needed the following supplies; one strawberry‚ one plastic cup‚ 10 ml of Cell Lysis Buffer (10% detergent‚ 1% NaCl)‚ one plastic zip-lock bag‚ one coffee filter‚
