Chemical reactions

Chemical replys are the heart of chemistry. plenty have always get by that they exist. The Ancient Greeks were the first offs to speculate on the composition of matter. They thought that it was getatable that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to situate on chemic reaction, specifically, combustion. He verbalise that a inwardness called phlogiston escaped into the take from all substances during combustion. He explained that a burning nuclear number 48 would go out if a candle snuff user was put all over it because the air inside the snuffer became saturated with phlogiston. According to his imaginations, woods is made up of phlogiston and ash, because only(prenominal) ash is left subsequent combustion. His judgments soon came upon some contradiction. When metallic element is burned, its ash has a grand mass than the real substance. Stahl attempt to cover himself by adage that phlogiston will take outside from a substances mass or that it had a negative mass, which contradicted his original theories. In the Eighteenth Century Antoine-Laurent Lavoisier, in France, discovered an important point in time in the understanding of the chemic reaction combustion, oxigine (oxygen). He state that combustion was a chemical reaction involving oxygen and some other combustible 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 blood corpuscles. Dalton besides verbalise that the way and dis port 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 affect that the volumes... If you want to get a full essay, order it on our website: Ordercustompaper.com
