Three Minutes Half Life
528 wordsThere are 109 known elements, and of those, 19 of them are artificially produced or synthetic. A synthetic element is made by bombarding atomic nuclei with neutrons or other particles. The element Lawrencium has been made in this manner. While scientists continue to work to create more elements, it should be noted that most synthetic elements are so unstable, that they are of theoretical value only, and have no known practical uses. This element was discovered at the Lawrence Radiation Laborator...

Organic Molecules Organic Matter
633 wordsDissolved oxygen infers to the volume of oxygen that is contained in water. Oxygen enters water through photosynthesis and across the water interface. The amount of oxygen that can be held by the water depends on the water pressure, salinity, and temperature. Gas solubility increases with decreasing temperature; thus colder water holds more oxygen. A reason why freshwater holds more oxygen than does saltwater is because gas solubility increases with decreasing salinity. When there is a change in...

Left Hand Side Atmospheric Pressure
1,199 wordsChemistry Independent Study: Gas Laws Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases...

Acetic Acid H 3
842 wordsIn the simple formalism proposed independently by Bronsted and Lowry in 1923, an acid was defined as a proton donor and a base was defined as a proton acceptor. In the simple acid-base reaction shown below, H 3 O+ is termed a Bronsted Acid, and HO- a Bronsted Base. In writing organic reaction mechanisms, the flow of electrons is often shown using "curved arrows" and in the example shown, the arrows are designed to show that an unshared pair of electrons from hydroxide anion moves to abstract a p...

(Destinations in Finland) Geographically, the served destinations are limited to the areas with the greatest number of people, which also means that they are serving the economic hubs of Finland. Estonian owned airline, Estonian Air serves only 10 destinations, all of which are large cities outside of its own country. However, lik...

Supply And Demand Quality Of Life
1,605 wordsUrban Sprawl Urban sprawl is the spread of urban congestion into adjoining suburbs and rural sections. (Brecher 34) Urban sprawl has become an issue for concern in the country since 1920. There was a rapid rate of sub urbanization between the years 1920 and 1950. Then by the seventies and eighties, urban sprawl has been curbed to moderate suburbanization. Urban sprawl has characterized American growth patterns for the past eighty years. There has been much controversy surrounding this hot topic....

Composed Of Particles State Of Density Dimension
395 wordsThe Facts of Life Existence is Truth Everything we know of is the third dimension, and its properties. Everything is composed of atoms, and atoms are composed of smaller particles. All particles are three dimensional because they have the dimension of height, the dimension of width, and the dimension of depth. Air is composed of particles in a low state of density, water is composed of particles in a more dense state, and physical objects are composed of particles in a high state of density. Thi...

Cm 3 M 2
347 wordsThe density of air In this experiment we are to measure the density of air. It is a quite simple experiment, you learn how important it is to measure exact and be aware of the sources of error when measuring such small quantities. The whole idea is that you know the mass of a certain volume of air, and then measure the volume. A digital scale that shows two decimals measures the first variable. We simply took a plastic bottle, weighed it when the lid was open, then with the help of a compressor,...

Lab Manual E Coli
1,139 wordsGene Regulation Using the Lac Operon Abstract Gene regulation in cells has been studied extensively in both eukaryotic and prokaryotic organisms. Gene control is employed as a way of saving the cell energy by only producing those enzymes it needs. In eukaryotes, genes are regulated so as maintain levels of cell specificity. In this experiment, the restriction of the production of the -galactosidase enzyme in the prokaryote Escherichia coli can be achieved by employing the lac operon. This operon...

Population Density Critical Thinking
440 wordsExercise 2: Mass Wasting Mass wasting is a phenomenon that has resulted in over one million deaths and billions of dollars of damage in its recorded history. Mass wasting is classified by the rate at which debris moves down slope. For instance, rockfalls move at speeds of over thirty-MPH, while mudslides travel at around twenty MPH. This field trip explored two translational slides; one at the Gros Ventre River in Wyoming, and the other at the Madison River in Montana. In Wyoming, the slide was ...

Square Mile Square Kilometer
1,377 wordsLions Lions are big animals with no fear of anything. They are harsh predators and will do anything to kill a prey for food. Some key facts about lions are that adult males grow approximately 9 feet from nose to tail. The females are a lot smaller than the males. Males usually weigh up to 350 - 550 pounds. The female lions weigh up to 250 - 300 pounds which is much smaller than the male lions growth. It takes most lions 3 to 4 years to sexually mature. The lions mating patter is non- seasonal wh...

Main Characters Popular Culture
1,779 wordsIdoru by william gibson is nothing less than an awe-inspiring book for me. no other author that i have come across can inspire one to recreate visions of reality at the turn of every page. Gibsons books are all compelling; neuromancer (1984) needing perhaps a special mention; as this book single handedly created the cyberpunk genre, aswell as coining phrases such as cyberspace. However, as one of his later works (1996), we are able to find within Idoru's more contemporary exploration of our worl...

Earths Atmosphere Boiling Point
469 wordsNeon was discovered in 1898 by British chemists Sir William Ramsay and Morris W. Travers as a component of the most volatile fraction of liquefied crude argon obtained from air. Upon applying an electric current to it, the chemists found that it had an orange glow, and they decided that it was not argon, but rather a new element altogether. Neon is not a very common element, but the places it is most abundant in are the earths atmosphere, and trapped within rocks in the earths crust. The place w...

Coronary Artery Disease Coronary Arteries
746 wordsQUESTION: What is Angina? And what is the cure? RESPONSE: Angina refers to the pain arising from lack of adequate blood supply to the heart muscle. Typically, it is a crushing pain behind the breastbone in the center of the chest, brought on by exertion and relieved by rest. It may at times radiate to or arise in the left arm, neck, jaw, left chest, or back. It is frequently accompanied by sweating, palpitations of the heart, and generally lasts a matter of minutes. Similar pain syndromes may be...

Population Density Rural Areas
493 wordsIn Cornwall there is not an even distribution of people living in Cornwall. But population density figures say that there are a certain number of people living in a sq. km. This is because it gives an average and does not take into account the large pop. density in cities and the small pop. densities in rural areas. In places like Truro there is a large population density, which is mainly richer. This is because it is the capitol of Truro and all the large chains want to put branches there. This...
