ANSWER:
Oxygen was discovered by two chemists working independently. They were Carl Scheele of Sweden and Joseph Priestley of England. Scheele's laboratory notes show that he prepared oxygen in the early 1770's by heating various compounds, including saltpeter, and mercuric oxide. But Scheele's experiments were not published until 1777. Priestley also published his experiments in 1777. He described how he prepared oxygen by heating mercuric oxide.
Scheele called oxygen "fire air." Priestley called it "dephlogisticated air." In 1777, the French chemist Antoine Lavoisier named the gas oxygen.
Mars is one of the five planets that can be seen without a telescope. It is unknown who first discovered Mars because it has been known since antiquity.
Vibrio vulnificus was discovered in 1976 by researchers at the Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, USA.
This could never happen Hydrogen Peroxide is madeby the process known as the Riedl-Pfleiderer process, having been first discovered by them in 1936. The overall equation for the process is simple:H2 + O2 → H2O2The economics of the process depend heavily on effective recycling of the quinone (which is very expensive) and extraction solvents, and of the hydrogenationcatalyst.
Ozone is not an element, it is an allotrope of oxygen. Ozone is formed in our atmosphere from a single oxygen atom combining with an oxygen molecule (O2). It was first produced in the lab by Christian Friedrich Schönbein in 1840. It was identified as O3 in 1865 by Jacques-Louis Soret and was the first discovered / recognized allotrope.
