And, the answer for the the question is :
Explanation:
Before the English chemist Joseph Priestley shone sunlight on a chunk of mercuric oxide and collected the ‘dephlogisticated gas’ that resulted from the reaction, no one was aware that oxygen was present in the atmosphere of the Earth. Oxygen makes up 21% of the atmosphere of the Earth. After another four years, the French chemist Antoine Lavoisier dubbed the newly discovered element “oxygen” after conducting research on the role the gas played in combustion.
In 1774, the English chemist and theologian Joseph Priestley made a groundbreaking discovery that would revolutionize our understanding of the natural world. Through his meticulous experiments and observations, Priestley famously identified and isolated a vital element: oxygen. This momentous finding not only paved the way for significant advancements in chemistry and biology but also fundamentally altered our comprehension of the composition and properties of the air we breathe.
Joseph Priestley’s journey toward the discovery of oxygen began with his fascination for gases and their properties. As a curious and inquisitive mind, he embarked on a series of experiments aimed at unraveling the mysteries of air. Through his meticulous work, Priestley discovered that certain substances produced a gas that was distinct from ordinary air.
In 1774, Priestley conducted an experiment that would change the course of scientific history. He discovered that by focusing sunlight on a sample of mercuric oxide, he could produce a gas with remarkable properties. This gas, later named “dephlogisticated air” by Priestley, was found to be highly reactive and capable of sustaining combustion more effectively than ordinary air.
Priestley’s groundbreaking research on dephlogisticated air laid the foundation for the identification of oxygen as a distinct element. However, it was the French chemist Antoine Lavoisier who would later coin the term “oxygen” to describe this vital component of the air. Lavoisier recognized the significance of Priestley’s discovery and dedicated his own research to further unraveling the properties and role of oxygen in chemical reactions.
The identification of oxygen marked a significant milestone in our understanding of the natural world. It challenged prevailing theories that attributed the process of combustion to a substance called “phlogiston.” Priestley’s experiments provided concrete evidence that combustion was, in fact, a result of the presence of oxygen, which combined with other substances during the chemical reaction.
The discovery of oxygen had profound implications across various scientific disciplines. It laid the groundwork for advancements in chemistry, as scientists began to explore the role of oxygen in different reactions and compounds. The understanding of oxidation and reduction, essential concepts in chemical reactions, was greatly expanded with the identification of oxygen as a key player.
Furthermore, the discovery of oxygen had a profound impact on our understanding of respiration and the process of breathing. It became clear that oxygen played a vital role in sustaining life, as it is necessary for the efficient functioning of cells and the production of energy through aerobic respiration. This understanding laid the foundation for advancements in the fields of physiology and medicine.
Joseph Priestley’s discovery of oxygen not only had scientific implications but also sparked broader p
