Chemical Reactions

Chemical reactions are the heart of chemistry. People have of all time cognise that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They notion that it was achievable that individual particles made up matter. Later, in the ordinal Century, a German chemist named Georg Ernst Stahl was the first to drive on chemic reaction, specifically, combustion. He verbalize that a substance called phlogiston escape into the demarcation from all substances during combustion. He explained that a burning see would go out if a candle snuffer was station oer it because the air inside the snuffer became saturated with phlogiston. check to his judgments, woodland is made up of phlogiston and ash, because only ash is leave later combustion. His ideas soon came upon some contradiction. When metal is burned, its ash has a great press than the original substance. Stahl tried to cover himself by reflexion that phlogiston will take away from a subst ances mass or that it had a negative mass, which contradicted his original theories. In the ordinal Century Antoine-Laurent Lavoisier, in France, discovered an important detail in the understanding of the chemic substance reaction combustion, oxigine (oxygen). He utter that combustion was a chemical reaction involving oxygen and an other(prenominal) combustible substance, such as wood. John Dalton, in the other(a) 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 also said that the mien and fade of properties meant that the atomic composit! ion dictated the appearance of different properties. He also came up with idea that a molecule of unrivaled 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 indispensableness to get a full essay, order it on our website: OrderCustomPaper.com
