Analysis of Carbon Dioxide CO2

- Analysis of Carbon Dioxide CO2 Carbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process....   [tags: Chemistry]

Why the Sea is Salty

- Why is the sea salty. One theory states that the sea is salt because of the “mid-Ocean” rift. Fresh basalt flows up through the rift along with “juvenile water; water that is made up of many of the components of sea water including chlorine, bromine, iodine, and many other molecules. Also some salts get into the ocean through volcanoes and even fresh water rivers carries salt into the sea. The sea is composed of many other things. Scientist over the years has conducted many experiments to prove not only of what the sea is made have but also many other things....   [tags: essays research papers]

- The Wilson’s Disease The Wilson’s disease is a genetic disorder of the thirteenth chromosome. This disease is an inherited disease and it is mostly likely to be in all of the offspring if a parent had it. It is the unnecessary increase of copper in the liver and brain. This is cause by a defect in the transport of copper. Wilson’s disease is a rare autosomal recessive disorder of the copper transport resulting in the copper buildup. It is also known as Hepatolenticular Degeneration as the scientific name....   [tags: essays research papers]

The Biological Importance of Water as a Solvent and as a Medium for Living Organisms

- The Biological Importance of Water as a Solvent and as a Medium for Living Organisms Water is possibly the most important substance life as we know it, as we need in order to survive; it also provides an environment for many species. All cells contain a minimum of 85% of water, with most fluids inside and outside of the cell likely to have at least 90% water. Both transportation of molecules and chemical reactions take place in dissolved water. In chemical terms, the water molecule is strongly dipolar, this property makes water a very effective solvent, particularly for crystalline salts .So, water is the solvent of the body & it regulates all functions, including...   [tags: Biology Essays]

- Cadmium, symbol, Cd, is a silvery white metallic chemical element with a faint blue tinge to it. It is the fifty-seventh most commonly found element in the earth. It was discovered by F. Stromeyer, in 1817, in Germany. Stromeyer was studying a sample of zinc carbonate which separated into a the new element ultimately called cadmium. The only cadmium materials, greenockite (cadmium sulfide) and otavile (cadmium carbonate) are found in zinc oxide and zinc carbonate. Cadmium, which is usually associated with zinc has some differences; some of which are that cadmium is softer and has a lower melting and boiling point than zinc....   [tags: essays research papers fc]

Chemical Makeup And Acid Base Reactions

- Exaction is where a solute is transfer from solvent A to solvent B (Ketcha, 47). A possible method to do this is changing the chemical makeup by using acid-base reactions (Ketcha, 42). The acid-base reactions change the solubility of the solute. If the original solute is ionic and is dissolvable is solvent A but not B, then adding the acid HCl would change the solute to its conjugate acid. The resulting acid would then be soluble in B but not A. To revert the change, just add the base NaOH to the solution....   [tags: Solvent, Solubility, Chemistry, Solution]

Water Is A Good Solvent And Picks Up Impurities Easily

- Water is a good solvent and picks up impurities easily. Pure water -- tasteless, colourless, and odourless -- is often called the universal solvent. Dissolved solids" refer to any minerals, salts, metals, cations or anions dissolved in water. Total dissolved solids (TDS) comprise inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulphates) and some small amounts of organic matter that are dissolved in water. TDS in drinking-water originate from natural sources, sewage, urban run-off, industrial wastewater, and chemicals used in the water treatment process, and the nature of the piping or hardware used to convey the water, i.e., the plumbing....   [tags: Water, Water pollution, Total dissolved solids]

The Effects of Recreational Drugs on the Body: The Bath Salts

Since the 1920’s bouncing around in the laboratories was mephedrone, since the 1960’s methylenedioxypyrovalerone has been in laboratories. So even though these drugs are not new the recreational use of them is new. Researchers are thinking the two main problems of bath salt are not being addicted to it but sleep deprivation which causes elevated stress hormone levels, depression, and psychosis, and the second being the dosage form there is no dosage so people just buy a bag and take it and then their brain says like it got to have it so they take more....   [tags: violent behavior, nausea, delusions, vomiting]

How the Human Body Obtains Cholesterol

- According to the scientific report from Gunness and Gidley (2010), the human body obtains cholesterol from two sources. The major source is liver. Liver synthesizes about 700-900 mg cholesterol per day. Another source is diet, which account for up to 300-500 mg/d. The major route cholesterol eliminates from human body is to convert to bile salts (BS) and excrete from the gastrointestinal tract (Gunness & Gidley, 2010). Bile salts (BS) are synthesized from cholesterol in the liver. Hydroxyl (OH) groups are inserted at several points of cholesterol, and then the second ring of cholesterol loses its double-bond....   [tags: liver, diet, metabolism]
