This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

Task 3: Tests for Anions: An Anion is an atom which is negatively charged therefore indicating a larger amount of electrons than proteins. Overall the tests for anions were mainly conclusive however 6 out of 8 of the anions we were testing for could only be determined from one specific result for example if a black precipitate formed following the tests the substance is therefore a sulphide however the same result would also show the presence of carbonate and hydrogen carbonate this therefore

Case Study 130 You are a nurse on an inpatient psychiatric unit. J.M.‚ a 23-year-old woman‚ was admitted to the psychiatric unit last night after assessment and treatment at a local hospital emergency department (ED) for “blacking out at school.” She has been given a preliminary diagnosis of anorexia nervosa. As you begin to assess her‚ you notice that she has very loose clothing‚ she is wrapped in a blanket‚ and her extremities are very thin. She tells you‚ “I don’t know why I’m here. They’re making

Chemistry of Fireworks By Anuradha Sahu Everyone enjoys the amazing firework shows on the Fourth of July with the beautiful vibrant colors and sparks every year. Fireworks have been part of this world for a very long time. They have been used for enjoyment and for signalling purposes. Every culture has their own significance and use of fireworks. But all fireworks have something in common; the chemistry that makes them work. No matter where you find them‚ they are made up of the same compounds

The History of the Discovery of Radiation and Radioactivity Introduction: Radiation can be defined as the propagation of energy through matter or space. It can be in the form of electromagnetic waves or energetic particles. Ionizing radiation has the ability to knock an electron from an atom‚ i.e. to ionize. Examples of ionizing radiation include: • alpha particles • beta particles • neutrons • gamma rays • x-rays Non-ionizing radiation does not have enough energy to ionize atoms in the material

To express his clear state of mind he keeps on using precise technical terms and elaborate‚ maybe stilted words and expressions: "alter the validity of my decision"‚ p. 29‚ 29; "lethargic and quiescent"‚ p. 29‚ 32; "catheter‚ enema"‚ p. 29‚ 33.

AgNO3. These are Iron (III) Nitrate‚ Barium Chloride‚ and Silver Nitrate. All of these are white solids that dissolve in water. We know that silver chloride is highly insoluble in water. So if we reacted an aqueous solution of each of the chemicals with a dilute solution of hydrochloric acid (HCI)‚ the one with Ag+ in it will form AgCl and precipitate as a solid. The other two samples will give no chemical reaction. We have now identified BaCl. We know that Barium Sulfate is highly insoluble in water
