bags. 5) Wear safety goggles. Should the worst happen, skin can be grafted. Eyes cannot be replaced. Ingredients Black Powder has traditionally consisted of three ingredients: Potassium Nitrate (KNO3, also known as Salt Peter), Sulfur and Charcoal. The Sulfur and Charcoal provide fuel for the reaction, while the Potassium Nitrate provides Oxygen. By themselves, Charcoal and Sulfur will burn, albeit very slowly. The addition of an oxidizer (such as KNO3) greatly speeds up the burn rate of the fuel
make up the basic fireworks: Oxidizers The first thing in a firework is the oxidizing agent. These produce the Oxygen to burn the mixture. Oxidizers are usually nitrates, chlorates or perchlorates. The common oxidizers are nitrates. These are made up of a metal ion and the nitrate ion. I'll use potassium nitrate as an example. Nitrates only give up 1/3 of their oxygen. The resulting equation would look something like this: 2KNO3 ---> 2KNO2 + O2 The next Oxidizers are chlorates are also
Potassium is an element on the periodic table that is symbolized by the letter K. The atomic number of this element is 19. At room temperature this element is a solid. Potassium can be found in two forms: either pure or compounds. Pure potassium is described as a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive in water However, Potassium forms many compounds such as Potassium chloride, which is the most common potassium compound (Gagnon, 1). This form of Potassium

Fluids and Electrolytes Homeostasis is the body’s way to maintain internal stability. Cells require certain conditions to function properly. The ability to produce energy is key to life. Animals eat food and take in liquids that the body breaks down to be used by cells to produce energy. Oxygen is required by cells to convert carbohydrates or sugars into energy. Fluids are responsible for the transportation of nutrients to cells and the transportation of waste products of energy production out of
Potassium Potassium is a vital element in the human body. Potassium had never been distinguished between sodium until the eighteenth century. Before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis
this lab, solutions of lead nitrate and potassium iodide will be mixed at a number of dilutions. The reactions will then be observed to see at which point a precipitate no longer occurs. Ksp will then be stated as a range of values at room temperature, and the precipitate test tubes will be heated until the precipitate is dissolved so that Ksp may be observed and determined at different levels. In this experiment various solutions of lead nitrate and potassium iodide were mixed at a number of different
Calcium and Potassium modifications are specialized individual according to a specific disease, age and inadequate amounts of calcium or potassium higher or lower than normal value. Calcium modifications are the results of to low or to high calcium levels. When calcium levels are to low compromises in bone integrity will occur. Adults 50 years of age and older are encouraged to increase calcium intake to help prevent osteoporosis. Patients with thyroid dysfunctions may experience low hormone levels
Sports drinks are used to supplement the loss of electrolytes, water and energy after exercise, helping the athlete recover quicker by replacing the key ionic-substances back into the body. They are designed to give the athlete an equal amount of carbohydrates and fluids to provide an almost instant rehydration and refuel during physical activity. This essay will explain the purpose of the contents of sports drinks and their uses in the human body. There are three main types of sports drinks; Isotonic
faster. Plants need twenty essentail elements to help them grow. Plants make carbohydrates. A plant needs nitrogen, phosphorus, potassium, calcium, sulfur, and magnesium the most to grow healthy. Most soils naturally contain enough trace elements for field crops, but such elements must be added when certain fruits and vegetable plants are grown. Nitrogen, phosphorus, and potassium are the top three elements needed in plant growth. Legumes are plants which absorb nitrogen gas from the air and bring the
that resembles rice water. it can become dangerous when the body loses a quarter of fluid in an hour. • Nausea and vomiting This occurs in the beginning and later stages of cholera. • Muscle cramps This happens due to loss of salt like sodium, potassium and chloride from the body. • Dehydration This can develop within hours of the onset cholera. This can range from mild to severe. The common symptoms of cholera dehydration are sunken eyes, irritability, lethargy, dry mouth, extreme thirst, little
of aluminum is 13; the element is in group 13 (IIIa) of the periodic table. Hans Christian Orstead, Danish chemist, first isolated aluminum in 1825, using a chemical process involving potassium amalgam. Between 1827 and 1845, Friedrich Wöhler, a German chemist, improved Oersted's process by using metallic potassium. He was the first to measure the specific gravity of aluminum and show its lightness. In 1854 Henri Sainte-Claire Deville, in France, obtained the metal by reducing aluminum chloride with
Epoxidation of Dihydronaphthalene with a Synthesized Jacobsen's Catalyst Abstract. 1,2 diaminocyclohexane was reacted with L-(+)-tartaric acid to yield (R,R)-1,2-diaminocyclohexane mono-(+)-tartrate salt. The tartrate salt was then reacted with potassium carbonate and 3,5-di-tert-butylsalicylaldehyde to yield (R,R)-N,N'-Bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediamine, which was then reacted with Mn(OAc)2*4H2O and LiCl to form Jacobsen's catalyst. The synthesized Jacobsen's catalyst was
difference between potassium and sodium was not discovered until the 18th century. "Vegetable alkali" also known as potassium carbonate came from the earth. "Mineral alkali" also known as sodium carbonate came from wood ashes. Early chemists did not recognise that these were two different chemical compounds. Sir Humphry Davy discovered potassium in 1807 in England, by isolating it using electrolysis. Potassium was the first metal to be isolated by using electrolysis. The name potassium originated from
Potassium is freely filtered in the glomerulus. Two thirds of the potassium is reabsorbed along the proximal tubule. The potassium concentration in the proximal tubule is roughly equal to that of plasma. In the descending limb of Henle a small amount of potassium is secreted into the luminal fluid and is reabsorbed by the ascending limb of Henle. The concentration of potassium is the distal convoluted tubule is now lower than the concentration in the plasma. The connecting tubule and cortical connecting
Introduction Proper organ function is dependent on keeping the correct balance of fluid and electrolytes within each body fluid space. There are many different electrolytes in the body. The most common ones are calcium, potassium, sodium, chlorine, phosphate and magnesium. Most electrolytes enter the body in ingested food. One of electrolytes, I would like to discuss in this paper is sodium. I choose sodium electrolyte because our bodies use sodium to control blood volume and blood pressure. Sodium
and cation of an unknown ionic compound. Materials and Methods: Project Part 1: Cation analysis In the first part of this project, two cation elimination tests and one cation confirmation test were performed. 10 drops of 4 cation solutions: potassium, zinc(II), copper(II)
When I was working as a bedside nurse in the Emergency Department, in one of my duties I was not satisfied with the treatment plan made by a resident doctor for XYZ patient. He entered intravenous KCL (potassium chloride) for the patient. The purpose of that medication and its dose for that patient was not clear to me. I assessed patient history and came to know that a middle aged patient came with the complaint of loose bowel movements, vomiting, and generalized weakness. His GCS (Glasgow comma
Nernst-derived equilibrium potential of potassium cannot sufficiently predict the membrane potential. In the experiment however our hypothesis was incorrect, we found no significant between the Nernst-derived equilibrium potential of potassium and the observed membrane voltage within crayfish tail muscle at extracellular potassium concentrations of 10mM, 20mM and 40mM. What this finding tells us is that our manipulation of altering the extracellular potassium concentration cannot be said to have changed
