Joseph Priestley is usually given priority in the discovery in 1774.
Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele. He had produced oxygen gas by heating mercuric oxide and various nitrates by about 1772. Scheele called the gas "fire air" because it was the only known supporter of combustion, and wrote an account of this discovery in a manuscript he titled Treatise on Air and Fire, which he sent to his publisher in 1775. However, that document was not published until 1777.
In the meantime, on August 1, 1774, an experiment conducted by the British clergyman Joseph Priestley focused sunlight on mercuric oxide (HgO) inside a glass tube, which liberated a gas he named "dephlogisticated air". He noted that candles burned brighter in the gas and that a mouse was more active and lived longer while breathing it. After breathing the gas himself, he wrote: "The feeling of it to my lungs was not sensibly different from that of common air, but I fancied that my breast felt peculiarly light and easy for some time afterwards." Priestley published his findings in 1775 in a paper titled "An Account of Further Discoveries in Air" which was included in the second volume of his book titled Experiments and Observations on Different Kinds of Air. Because he published his findings first, Priestley is usually given priority in the discovery.
Oxygen was "discovered" by a number of scientists over a fairly brief time period. First discovery is normally credited to the Swedish scientist Carl Wilhelm Scheele in 1772. He called his discovery "fire-air" because it supported combustion.Unfortunately (for him), Scheele's findings weren't published until 1777. In the interim, British clergyman and chemist Joseph Priestley, in 1774, discovered oxygen independently. He called it "dephlogisticated air." (Aren't you glad we don't call it that today?)Across the English Channel, French scientist Antoine Lavoisier claimed to have discovered oxygen independently in 1775. Priestley, however, claimed that he had visited Lavoisier in 1774 and talked with him about his (Priestley's) experiments, so the independence of Lavoisier's "discovery" is questionable.Lavoisier did contribute two important things to the discovery of oxygen, though: He was the first to deduce that oxygen was a separate element, and he gave it the name by which we know it today. Oxygen, from Greek roots that mean "acid-producer," was so named because of Lavoisier's belief that oxygen was present in all acids.

Dissolve oxygen is when oxygen is dissolved and oxygen is just normal oxygen!

I don' t know
Oxygen was discovered by Joseph Priestley and Carl Scheele in 1774.
in the human heart
Oxygen is used in the launch of space vehicles to make discoveries.
He changed the science of chemistry from Quantitative to qualitative and is most noted for his discovery of the role that oxygen plays in combustion.
The word is spelled oxygen. Humans breathe oxygen and release carbon dioxide. Plants use carbon dioxide and release oxygen.
British scientist Joseph Priestley is credited for his discovery of oxygen. He lived from 1733 to 1804.
