论文代写：氧气的发现
氧气的发现发生在1770年，而不是在1850年代。它通常归功于Joseph Joseph Priestly。在发现氧气的时候，化学的概念和原理就像炼金术。人们不了解氧气的概念。他们认为这个世界是由空气，土壤和火焰组成的。周期表尚未设计。 1774年，归因于普里斯特利发现了氧气。然而，1772年，Karl W. Scheele详细介绍了氧气的发现。直到1777年，他才发表了他的发现。在这个故事中，复古诺贝尔委员会为确定发现氧气的奖励做出了艰难的决定。 Carl Wilhelm Scheele，Joseph Priestley和Antoine Laurent Lavoisier是三位获得冠军头衔的选手。普里斯特利发现了一种会引起燃烧的化合物，拉瓦锡试图对这些化合物进行系统分类。尽管如此，Scheele并没有被视为他在后来的数据中发表了他的发现。氧气是一种具有许多重要科学含义的化合物。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Priestly的原因是他早日发布了这一发现，并为其他重要理论奠定了基础。这是从科学的角度出发的。
论文代写：氧气的发现
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.
