Chemical reactions

Chemical replys are the heart of chemistry. People have perpetually know that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They sight that it was attainable that individual particles made up matter. Later, in the ordinal Century, a German chemist named Georg Ernst Stahl was the first to situate on chemical reaction, specifically, combustion. He verbalise that a effect called phlogiston take flight into the channel from all substances during combustion. He explained that a burning wick would go out if a candle snuffer was institutionalize everyplace it because the air inside the snuffer became saturated with phlogiston. fit in to his imaginations, woodwind is made up of phlogiston and ash, because only ash is odd later combustion. His ideas soon came upon some contradiction. When metal is burned, its ash has a great passel than the original substance. Stahl tried to cover himself by apothegm that phlogiston will tak e away from a substances mass or that it had a negative mass, which contradicted his original theories. In the 18th Century Antoine-Laurent Lavoisier, in France, discovered an important detail in the understanding of the chemical reaction combustion, oxigine (oxygen). He said that combustion was a chemical reaction involving oxygen and another inflammable substance, such as wood. John Dalton, in the early 19th Century, discovered the atom. It gave way to the idea that a chemical reaction was actually the rearrangement of groups of atoms called tinges. Dalton excessively said that the way and disappearance of properties meant that the atomic composition dictated the appearance of different properties. He also came up with idea that a molecule of one substance is exactly the same as any other molecule of the same substance. People like Joseph-Lois Gay-Lussac added to Daltons concepts with the postulate that the volumes... If you want to function a full essay, order it on our web! site: BestEssayCheap.com
