The Element: Chlorine
Words: 1163 / Pages: 5

.... elements chlorine has a strong tendency to gain one electron and become a chloride ion. Chlorine readily reacts with metals to form chlorides, most of which are soluble in water. Chlorine also reacts directly with many nonmetals such as sulfur, phosphorus, and other halogens. Chlorine can support combustion; if a candle were to be thrown into a vessel of chlorine, it would continue to burn, releasing dense, black clouds of smoke, The chlorine combines with hydrogen of the paraffin, forming hydrogen chloride, and uncombined carbon is left in the form of soot. Soot is black residue from fuel. Chlorine replaces iodine and bromine from their salts. Dry .....


What Is Physics And What Are Its Uses?
Words: 504 / Pages: 2

.... ball with enough arch to get over the front of the rim, and go through the hoop. The energy required to do this comes from not only the arms, but the legs as well. The medical field has seen enormous breakthroughs because of principles of physics. Doctors are now able to use lasers for surgery. Lasers are based on the physical principle of light, and are devices for the creation and amplification of a narrow, intense beam of coherent light. New laser microsurgery can actually alter the shape of the cornea in the eye so the patient's eyesight can return to normal, and he/she will no longer need those bothersome glasses. Ultrasound is used in the .....


Deforestation Of The Pacific Northwest
Words: 1195 / Pages: 5

.... its' habitat. It is the latter part of the bill that causes the controversy. Under the ESA, loggers should not be allowed to cut down the old- growth of the forest. The old growth of a forest includes the largest and oldest trees, living or dead. In the case of the North Coast forests, this includes some thousand-year-old stands with heights above three-hundred feet and diameters of more than ten feet. In 1990, the number of spotted owls dropped to 2000 breeding pairs. The preservation of any species contributes to the biodiversity of an area. In an ecosystem, the absence of one species creates unfavorable conditions for the others. The absen .....


Pollution And The Environment
Words: 767 / Pages: 3

.... did a long time ago. A big reason is due to pollution. These animals’ homes are taken away because of the trash content everywhere. It is not fair to these animals whose food and shelter always gets contaminated. When these animals get killed, it breaks a part of the food chain. If an animal is taken out of the chain, the other animals that eat that one will go hungry, therefore killing them off too. Contaminated food has already happened to the food humans eat. For example, the Mad Cow Disease. This disease slowed the beef market down and it is easily happening in the other ocean creatures market. Humans have no right to kill what is not theirs, .....


Human Cloning Isn't As Scary As It Sounds
Words: 1335 / Pages: 5

.... It would be more like producing a delayed identical twin. And just as identical twins are two separate people—biologically, psychologically, morally and legally, though not genetically—so a clone is a separate person from his or her non-contemporaneous twin. To think otherwise is to embrace a belief in genetic determinism—the view that genes determine everything about us, and that environmental factors or the random events in human development are utterly insignificant. The overwhelming consensus among geneticists is that genetic determinism is false. As geneticists have come to understand the ways in which genes operate, they have also become .....


Acid Base Extraction
Words: 1499 / Pages: 6

.... goal of this experiment was to identify the three components in the mixture and to determine the percent recovery of each from the mixture. 4) Separation of a Neutral and Basic Substance A mixture of equal parts of a neutral substance containing either naphthalene or benzoin and a basic substance containing either 4-chloroaniline or ethyl 4-aminobenzoate were to be separated by extraction from an ether solution. Once the separation took place, and crystallization was carried out, it became possible to determine what components were in the unknown mixture, by means of a melting point determination. Results Procedure .....


Acupuncture
Words: 410 / Pages: 2

.... of the pulses. There are three main methods of diagnosis that are employed in the clinic: looking, asking and palpating, all of which contribute to a full and accurate diagnosis of the patient’s condition. By looking at the patient’s face, body and movements, the practitioner is already beginning to create a diagnosis. Another major diagnostic tool is the tongue. It is said that the state of the internal organs is reflected in the tongue, and the practitioner will note the color and shape of the tongue as well as its coating. All patients can expect their pulse to be taken. Unlike a Western doctor, the acupuncturist is not feeling merely the spee .....


Solar Energy: An Alternative Energy
Words: 290 / Pages: 2

.... Solar energy is the visible energy produced in the sun as a result of a constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared. A calorie is the amount of energy needed to raise one gram of water one degree Celsius. If we could efficiently harness the energy bombarding the earth for twenty-four hours we could power New York for a year. Unfortunately the photovoltaic cells that change the energy into electricity are so inefficient that it would take twenty-five years to pay for it's self in output. There many use .....


Hard Drive Evolution
Words: 988 / Pages: 4

.... of corporate data centers. The personal computer revolution in the early 1980s changed all that, ushering in the introduction of the first small hard disk drives. The first 5.25-inch hard disk drives packed 5 to 10 MB of storage, the equivalent of 2,500 to 5,000 pages of double-spaced typed information, into a device the size of a small shoebox. At the time, a storage capacity of 10 MB was considered too large for a so-called "personal" computer. The first PCs used removable floppy disks as storage devices almost exclusively. The term "floppy" accurately fit the earliest 8-inch PC diskettes and the 5.25-inch diskettes that succeeded them. The inner .....

Words: 1454 / Pages: 6

.... are in the short term, it has terrible consequences and its long term effects are devastating, this is why it should be stopped. Since its discovery, 30% of Brazil's rain forests have disappeared, and the country is still losing more rain forest each year than any other on the planet. Brazilian forests are burned or felled at the rate of 1800 hectares (about 4500 acres) every hour! (Dwyer 39) Deforestation started hundreds of years ago, but only became a major problem in the second half of this century, when it increased dramatically. It was enhanced by the Brazilian government which started cutting down the forest to construct a vast network of .....
