Chemical Reactions

chemical substance substance reactions are the heart of chemistry. nation have al airs know that they exist. The Ancient Greeks were the sources to speculate on the composition of matter. They thought that it was come-at-able that individual particles made up matter.\n\nLater, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to fight on chemical reaction, specifically, combustion. He express that a substance called phlogiston escaped into the crinkle from all substances during combustion. He explained that a burning wick would go out if a candle snuff user was put over it because the air inside the snuffer became saturated with phlogiston. According to his minds, woods is made up of phlogiston and ash, because provided ash is left aft(prenominal) combustion. His ideas soon came upon some contradiction. When alloy is burned, its ash has a greater mass than the original substance. Stahl seek to cover himself by axiom that phlogiston wi ll take out from a substances mass or that it had a negative mass, which contradicted his original theories.\n\nIn the Eighteenth Century Antoine-Laurent Lavoisier, in France, discovered an important lucubrate in the apprehensiveness of the chemical reaction combustion, oxigine (oxygen). He say that combustion was a chemical reaction involving oxygen and some some an opposite(prenominal) combustible substance, such as wood.\n\nJohn Dalton, in the advance(prenominal) Nineteenth Century, discovered the atom. It gave way to the idea that a chemical reaction was actually the rearrangement of groups of atoms called molecules. Dalton besides said that the appearance and disappearance of properties meant that the atomic composition fixed the appearance of different properties. He also came up with idea that a molecule of hotshot substance is exactly the equal as any other molecule of the akin substance.\n\n batch like Joseph-Lois Gay-Lussac added to Daltons concepts with the postulate that the volumes of gasses that react with each other are related (14 grams of normality reacted with exactly three grams of hydrogen, octette grams of oxygen reacted to exactly i gram of hydrogen, etc.)\n\nAmedeo Avogadro also added to the understanding of chemical reactions. He said that all gasses at the alike pressure, volume and temperature contain the same number of particles. This idea took a long time to be accepted. His ideas lead to the subscripts used in the formulas for gasses.\n\nFrom the work of these and many other chemists, we now have a...If you indispensability to get a unspoiled essay, order it on our website:
