Analytical Chemistry Analytical Chemistry Analytical Chemistry is the branch of chemistry principally concerned with determining the chemical composition of materials, which may be solids, liquids, gases, pure elements, compounds, or complex mixtures. In addition, chemical analysis can characterize materials but determining their molecular structures and measuring such physical properties as pH, color, and solubility. Wet analysis involves the studying of substances that have been submerged in
Aristotle Aristotle One of the greatest thinkers of all time was Aristotle-322 BC, the Ancient Greek philosopher. He has practically influenced every area of present day thinking. His main focal points were the natural and social sciences. In Stagira, a town on the northwest coast of the Aegean Sea, in the year of 384 BC Aristotle was introduced to the world. He grew up a wealthy boy. His father was friends with the noble king of Macedonia, and as a young man he spent the majority of his time a
Diet and Cancer... What is the Link? Diet and Cancer... What is the Link? Today we know that too much of a certain type of foods can have harmful effects on our health and well-being and we are learning that diseases such as cancer are caused in part by our dietary choices. In the 1950\'s scientists discovered relationship between diet and coronary heart disease, the nations number one killer. In the last 15 year a link between cancer and diet has been discovered by scientists. The National Aca

By virtue of the education he received in m
Marie Curie: A Pioneering Physicist Marie Curie: A Pioneering Physicist Aspirations come from hopes and dreams only a dedicated person can conjure up. They can range from passing the third grade to making the local high school football team. Marie Curie\'s aspirations, however, were much greater. Life in late 19th century Poland was rough. Being a female in those days wasn\'t a walk in the park either. Marie Curie is recognized in history by the name she took in her adopted country, France. Bor
Oxygen Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of
The Ozone Layer The Ozone Layer In environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earth’s surface warmer than it would normally be. The atmosphere is primarily transparent to infrared radiation from the sun, which is mostly absorbed by the earth’s surface. The earth being much cooler than the sun, remits radiation most strongly at infrared wavelengths. Water vapor, carbon dioxide and ozone then absorb much of
Chemical Engineer Chemical Engineer The chemical engineer is an invaluable link between scientific principles and manufacturing realities. It involves the use of chemical, physical, and engineering principles. The scientist in a laboratory does basic research to develop new compounds and processes. When the scientist discovers a product that may be useful, the chemical engineer takes over. They adapt the product for big scale manufacturing. They do this by designing a plant to produce the item
The Atom The Atom AP Physics Period 2 In the spring of 1897 J.J. Thomson demonstrated that the beam of glowing matter in a cathode-ray tube was not made of light waves, as the almost unanimous opinion of German physicists held. Rather, cathode rays were negatively charged particles boiling off the negative cathode and attracted to the positive anode. These particles could be deflected by an electric field and bent into curved paths by a magnetic field. They were much lighter than hydrogen ato
The Orgins of Atomic Theory The Orgins of Atomic Theory By Levi Pulkkinen There is an eternal human compulsion to unlock the mysteries of our lives and our world. This search for knowledge has guided us to many beneficial new understandings. It has lead us into this new age where information is its own reward, an age where enlightenment is an end, not simply a means to an end. Enlightenment has been the aim of many great people. It has inspired many scientists and artists to construct articles
Acid rain is pollution Word Count: 601 Acid rain is a common term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce a rain, snow, or hail of sulfuric and nitric acids. Such pollution may also be suspended in a fog, or the pollutants may be deposited in dry form. Environmental damage from acid rain has been reported in northern Europe and North America. High levels of acid rain have also been detected in other areas of the world, such as above th

Global Warming Global Warming The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earth\'s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the “greenhouse effect.”). The gases--water vapor (H2O), carbon dioxide (CO2), and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them
The Atmospheric Ozone Layer The Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmosp

Is Euthanasia Immoral? Is Euthanasia Immoral? Mr. Blackburn Inquiry Skills 2 Dec. 1996 In today\'s society there are many disagreements about the rights and wrongs of euthanasia. Although death is unavoidable for human beings, suffering before death is unbearable not only for terminal patients but for the family members and friends. Euthanasia comes from the Greek word Thanatos meaning death and the prefix eu meaning easy or good (Russell 94). Thus, eu- Thanatos meaning easy or good death
Ancient Egypt Ancient Egypt Starting about 8,000BC, all of Northern Africa became a drier, more desert-like place. Back then, man lived in nomadic groups of hunters and gatherer. The climate forced man to migrate to more hospitable lands, some migrated to Nile River Valley which is a vast land surrounding the Nile River. There in this land abundant with life, there were plenty of food and water for these people. During the Neolithic Revolution (10,000BC to 3,500BC) man discovered the art of agr

Serial Killers in the U.S Serial Killers in the U.S Before we can discuss what serial killers do, we must first define what a serial killer is. Some people might place serial killers into the same group as mass murderers. This would be incorrect because they are two totally different types of killers. While both of these individuals may kill many people, the difference lies in the reason they kill and the period over which they kill their victims. An event or a build up of circumstance triggers
