Chlorine was discovered in?
Chlorine gas was first observed by a Belgian chemist, Jan Baptist van Helmont, in about the year 1630, but the Swedish chemist Carl Wilhelm Scheele is credited with isolating Chlorine as an element in 1774, although he didn't recognize it as an element. That realization came in the early 1800's. Chlorine gas was first used as a weapon on April 22, 1915, at the Battle of Ypres. For more information, look up "Chlorine" on Wikipedia.
When was the oxygen discovered?
i am not sure but i do know who discovered it...... Carl Wilhelm Scheele in 1772 but did not publish it until 1777 or 1778 another person named Joseph Priestly discovered it in 1774 and published it in 1775 and takes more credit on oxygen's discovery.
How much oxygen does one person use per year?
Let's calculate Breaths per minute say 15 Liters per breath about 1 so oxygen per breath about 0.2 liters. 15 X 60 (mins a hour) X 24 (hours a day) X 365 (days a year) = about 8,000,000 X 0.2 liters (ratio of oxygen in air) = 2,000,000 liters of oxygen Oxygen gas weighs about 1 gram per liter so in a year you breathe in about 2 tons of oxygen. These are all estimates but i think the answer will be within about 25%.

Who invented chlorine?
the year 1774 Chlorine was observed for the first time by Jan Baptist van Helmont near 1630 (in Holland) and prepared for the first time in laboratory by Carl Wilhelm Scheele in 1774 (in Sweden), but considered it to be a compound of oxygen. Sir Humphry Davy (in England) named it after identifying chlorine as a chemical element in 1810.

What chemist is given credit for discovering oxygen?
Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele in 1772 by heating mercuric oxide and nitrate salts. (But don't try this at home: both very toxic experiments). Also there was a main quarrel about the 'first' claim between Priestly (VIII-1774) and Lavoisier (1774, later) and Scheele (letter in IX-1774, but found after his death)
How was oxygen was discovered?
Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an English chemist, independently, discovered oxygen in 1774 and published his findings the same year, three years before Scheele published. Antonie Lavoisier, a French chemist, also discovered oxygen in 1775, was the first to recognize it as an element, and coined its name "oxygen" - which comes from a Greek word that means "acid-former".
