1,481 wordsRight now I'm thinking about the Internet, the all-pervasive medium through which I've published my thoughts and work I've done in my free time for several years now. Like mostly everyone else, I communicate with others using the Internet, play games through it, read news, and learn about things. (Except, sadly, I am not convinced the general public is interested in learning. ) And we are all familiar with the "dot com mania" and the insane rise in the NASDAQ - and, sadly, the subsequent fall of...

H 2 O X 10
1,265 wordsAvogadro's number is the number 6. 0221367 x 10 ^ 23, commonly rounded to just three significant digits: 6. 02 x 10 ^ 23, and is the number of representative particles in a mole. Avogadro's number is commonly used to compute the quantities of substances involved in chemical reactions, called stoichiometry, and is one of the most important and versatile components of modern chemistry. Avogadro's number is named after the Italian physicist Amadeo Avogadro. Avogadro's number first came about when A...

Life On Earth H 2 O
726 wordsThe first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

Ph Of 5 Sulphur Dioxide
1,087 wordsAcidity is measured using a pH scale, with the number 7 being neutral. A substance with a pH value of less than 7 is acidic, while one of a value greater than 7 is basic. A substance with a pH of 6 is 10 times more acidic than another with a pH of 7. Usually the pH of 5. 6 has been used as the baseline in identifying acid rain, although there has been much debate over the acceptance of this value. Interestingly enough, a pH of 5. 6 is the pH value of carbon dioxide in equilibrium with distilled ...

The Biological Importance Of Water
1,055 wordsGenerally, the main biological importance of water is that life cannot exist without it. In fact on a percentage basis, the majority of any organism is comprised of water. Additionally, it is believed that life first originated in the bodies of water on the earth. The importance of water is seen in such third world countries as Kenya. Where the inhabitants are forced to drink water so dirty and contaminated that they know it might kill them. However they still drink it because its essential for ...

Three Minutes 000 Years
619 wordsWhere is the universe from? Where is it going? How is it put together? How did it get to be this way. These are Big questions. Very easy to ask but almost impossible to answer. We want answers for philosophical reason having nothing to do with science. No one will get rich from discovering the structure of the universe unless they right a book about it. The area of science dealing with Big questions is called cosmology. The reason for it's study is found in the fact that: The universe was born a...

Nitric Acid Scientific American
825 wordsChemistry Connections of nitrogen - saltpeter, nitric acid, ammonia - were known long before invention of nitrogen in a free condition. In 1772 D. Rutherford, burning phosphorus and other substances in a glass bell, has shown that the gas remaining after combustion does not support breath and burning. He named it suffocating air. In 1787 A. Lavoisier has established, that the "vital" and "suffocating" gases included in air, are simple substances, and has offered the name "nitrogen." In 1784 G. C...

Friction At The Atomic Scale
1,010 wordsFriction at the atomic scale. From the article "Friction at the Atomic Scale" by Jacqueline Krim we learn that standard friction and friction at the atomic scale are quite different. In my summary paper I would like to try to explain that fact based on the article. Having used different apparatus, the scientists made an experiment to prove that physicists didnt pay enough attention to the study of frictions atomic level or nano tribology for a long time wrongly. However now it was determined tha...

Burning Of Fossil Fuels Humans And Animals
668 wordsCarbon Dioxide is a colorless, odorless gas that occurs in small quantities in the earths atmosphere naturally. The earths ocean, soil, plants and animals release CO 2. The formula of Carbon Dioxide is CO 2. The CO 2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon oxygen double bonds. The atoms are arranged as so (OHT). This is called a linear molecule. Carbon dioxide is commonly found as a gas and is never a liquid. It sublimes to a solid known a...

Hydrogen And Oxygen Simple Sugars
329 wordsCarbohydrate Structure and Function Carbohydrates are molecules composed of carbon, hydrogen, and oxygen. They are polymers of the basic units called monosaccharides. Dissaccharides are compound sugars, composed of two monosaccharides, (simple sugars) bonded together. Molecular Structure For example, two molecules of glucose can bond together to form the Disaccharide Maltose. Sucrose and Lactose are other common Disaccharides. Dissaccharides are formed through condensation reactions that result ...

Cause A Person Locke Theory
1,857 wordsThe idea of sound will be investigated in the following essay. Is there sound in the world and if a tree falls in the forest and there is no body around does it actually make a noise? These ideas will be followed by the theory of colour. Individuals think they see colour, so people believe there is colour in the world and do not even think twice about the issue. Still, some philosophers have presented ideas about the world with no colour. Is this theory plausible? Following these two questions, ...

Books New York Stratospheric Ozone
1,223 wordsChloroflourocarbons were discovered in the 1920 s by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non-toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC- 12) and trichloromonoflouromethane (CFC- 11). In both compounds, different amounts of chlorine and fluorine are combined with methane, which is a combination of carbon...
