代写论文：化学物—氧
氧气的发现发生在1770年，而不是在19世纪50年代。它通常被认为是约瑟夫·普利斯特里的功劳。在发现氧气的时候，化学的概念和原理就像炼金术一样。人们不理解氧的概念。他们以为世界是由空气、地球和火组成的。周期表还没有设计出来。1774年，人们把Priestley发现为氧气。然而，1772年，卡尔·w·舍勒详细描述了氧气的发现。直到1777年，他才发表了他的发现。在这个故事中，反诺贝尔奖委员会很难确定发现氧气的奖项。卡尔·威廉·舍勒(Carl Wilhelm Scheele)、约瑟夫·普利斯特里(Joseph Priestley)和安托万·洛朗·拉瓦锡(Antoine Laurent Lavoisier)是三名被认为是冠军的选手。Priestley发现了一种引起燃烧的化合物，拉瓦锡试图系统地对这些化合物进行分类。尽管如此，舍勒并没有在后来的数据中发表他的发现。氧是一种化合物，它有许多重要的科学含义。氧气的发现使人们了解了许多重要的理论。委员会将这一发现归因于祭司的原因是，他在早些时候发表了这一发现，并为其他重要理论奠定了基础。这是科学的观点。、

The discovery of oxygen occurred in 1770 and not in 1850s. It is usually attributed and credited to Joseph Priestly. At the time of discovery of the oxygen, the notions and principles of chemistry were like alchemy. The people did not understand the concept of oxygen. They assumed that the world was made of air, earth and fire. The periodic table was not yet devised. In 1774, it was attributed that Priestley was discover oxygen. However, in 1772, Karl W. Scheele detailed the discovery of oxygen. He did not publish his findings until 1777. In the story, the retro-Nobel committee makes difficult determination for identifying the award for the discovery of oxygen. Carl Wilhelm Scheele, Joseph Priestley and Antoine Laurent Lavoisier were the three contestants who were considered for the title. Priestley had discovered a compound that causes combustion and Lavoisier tries to systematically classify the compounds. Nevertheless, Scheele is not considered as he had published his findings at a later data. Oxygen is a compound that has a number of important scientific implications. The discovery of Oxygen has caused the people to understand many of the important theories. The reason that the committees attribute the discovery to Priestly is that he published it at an earlier date and lays the foundation to other important theories. This is from a scientific perspective.
