    Antoine Lavoisier (1743-1794) Antoine-Laurent Lavoisier (lah vwah ZYAY) was one of the best-known French scientists and was an important government official. His theories of combustion, his development of a way to classify the elements and the first modern textbook of chemistry led to his being known as the father of modern chemistry. He contributed to much of the research in the field of chemistry. He is quoted for saying, Nothing is lost, nothing is created, everything is transformed. Lavoisier was born in Paris, France on Aug. 26, 1743. When he was eleven years old he attended a college called Mazain. For Lavoisier's last two years in college he found a great deal of interest in science. ...

  • Chemical Reactions - 1,932 words
    Chemical Reactions Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substances during combustion. He explained that a burning candle would go out if a candle snuffer was put over it because the air inside the snuffer became saturated with phlogiston. According to his ideas, wood is ...

  • Combustion Carbon Dioxide - 1,146 words
    COMBUSTIOn & carbon Dioxide Research By Rabon Hutcherson II. Combustion and carbon dioxide, what are they? When people think of combustion they probably think of simple just bursting into flames; and for carbon dioxide you probably think of what we breath out and what plants take from the air and turn to oxygen. Even though these thoughts are true there is much more to combustion and carbon dioxide. Things you might not think of about combustion are, mathematical equations, models, solutions and chemical reactions, and for carbon dioxide dry ice, combustion and it being a solid. All of these factors you may not have known are now here for you to see. One of the things that has lead the way f ...

    History Of Chemistry History of Chemistry Introduction: Humans have always been very curios creatures. The have always wondered about what they are and why they are here. Our limited knowledge of the environment has always urged for new things to be discovered. The desire to understand the world better has made people search for rational answers, for principles and laws. For centuries people have tried to unlock the mysterious world that surrounds them. History: Because myths did not explain things well enough the Greeks began to ask questions about the world around them. They did this so thoroughly and so brilliantly that the era between 600 and 400 B.C. is called the golden age of philosop ...

  • Hydrogen - 1,153 words
    Hydrogen Hydrogen in its liquid form has been used in space vehicles for years. Hydrogen has a high combustion energy per pound relative to any other fuel, meaning hydrogen is more efficient on a weight basis than fuels currently used in air or ground transportation. Hydrogen is the universes most abundant element. Most of that hydrogen though, is tied up in chemical bonds. Hydrogen can exist in either a gaseous form or a liquid form. Hydrogen is The liquid form is usually used for storage while the gaseous form is used as a heat transfer, and also as a cooling agent in nuclear power plants. The name hydrogen is Greek for water former. Hydrogen was once called "inflammable air" by a British ...

  • Hydrogen - 638 words
    HYDROGEN Hydrogen, symbol H, is reactive, colorless, odorless, and tasteless gaseous element. The atomic number of hydrogen is 1. The element is usually classed in group 1 of the periodic table. Hydrogen was confused with other gases until the a British chemist demonstrated in 1766 that it was evolved by the action of sulfuric acid on metals and also showed at a later date that it was an independent substance that combined with oxygen to form water. The British chemist Joseph Priestley named the gas "inflammable air" in 1781, and the French chemist Antoine Laurent Lavoisier renamed it hydrogen. Like most gaseous elements, hydrogen is diatomic, but it becomes and turns into free atoms at high ...

  • Oxygen - 1,125 words
    Oxygen Oxygen is one of the 92 known elements. An element is a substance that cannot be decomposed into a simpler substance by any simple means. Each of the 92 naturally occurring elements are therefore one of the fundamental materials from which everything in the Universe is made. The History of Oxygen On August 1,1774, Joseph Priestley examined the effect of intense heat on mercuric oxide. He noted that an air or gas was readily expelled from the specimen. To his surprise a candle burned in this with a remarkably vigorous flame. He called this new substance dephlogisticated air, in terms of the current chemical theory of combustion. On a visit to Paris in 1775 he related his discovery dire ...

  • Periodic Table - 348 words
    Periodic Table Periodic Table First noticed by Greek people in about 400BC. They used the words "element", and "atom" to describe the differences and smallest parts of matter. Those ideas lasted for 2000 years. Elements were Earth, Fire, Air, and Water that explained "world stuff" easily came and went. In the 1600's Boyle, an experimenter, influenced by Democritus, Gassendi, and Descartes lent important weight to the atomic theory of matter. In the 1700's Lavoisier divided the elements into four classes. John Dalton suggested that the mass of an atom is the important property. "The chemical elements are composed of... indivisible particles of matter, called atoms... atoms of the same element ...

  • Science Alchemy Alchemy, Ancient Art Practiced Especially In The Middle Ages, Devoted Chiefly To Discovering A Substance That - 850 words
    Science Alchemy Alchemy, ancient art practiced especially in the Middle Ages, devoted chiefly to discovering a substance that would transmute the more common metals into gold or silver and to finding a means of indefinitely prolonging human life. Although its purposes and techniques were dubious and often illusory, alchemy was in many ways the predecessor of modern science, especially the science of chemistry. The birthplace of alchemy was ancient Egypt, where, in Alexandria, it began to flourish in the Hellenistic period; simultaneously, a school of alchemy was developing in China. The writings of some of the early Greek philosophers might be considered to contain the first chemical theorie ...

  • Things Are Different From Each Other, And Each Can Be Reduced To Very Small Parts Of Itself Ancient Knowledge - 596 words
    Things are different from each other, and each can be reduced to very small parts of itself. - Ancient knowledge This was noticed early by people, and Greek thinkers, about 400BC, used the words "element', and `atom' to describe the differences and smallest parts of matter. These ideas survived for 2000 years while concepts such as `Elements' of Earth, Fire, Air, and Water to explain `world stuff' came and went. Much later, Boyle, an experimenter like Galileo and Bacon, and who was influenced much by Democritus, Gassendi, and Descartes, lent important weight to the atomic theory of matter in the 1600s. It was Lavoisier who divided the few elements known in the 1700's into four classes, and t ...
