Joseph Priestley, through experiments with gases, demonstrated that "dephlogisticated air" (what we now know as oxygen) was distinct from "fixed air" (carbon dioxide) by observing their different properties. He showed that dephlogisticated air supported combustion and respiration, while fixed air did not. Additionally, he found that dephlogisticated air produced a brighter flame and was absorbed by substances like rusting iron, which further distinguished it from fixed air. This helped lay the groundwork for understanding the composition of air and the nature of gases.

How do you think ingenhousz showed that it was dephlogisticated and not fixed air?
Ingenhousz demonstrated that oxygen (dephlogisticated air) was produced during photosynthesis by showing that plants release this gas in the presence of light. This was different from fixed air (carbon dioxide) because plants were observed to only release oxygen in the light, suggesting a direct relationship between the presence of light and the production of oxygen.
What was dephologisticated air?
dephlogisticated air is oxygen gas; - so called by Dr. Priestly and others of his time.
How does Jan Ingenhousz may have collected a sample of dephlogisticated air?
Jan Ingenhousz likely collected a sample of dephlogisticated air, which we now understand as oxygen, by using a method involving the photosynthesis of aquatic plants. He placed water plants in sunlight and observed that they released bubbles, which were primarily composed of oxygen. By capturing these bubbles in an inverted container filled with water, he could collect and analyze the gas, thus isolating what he termed dephlogisticated air. This experimentation contributed significantly to the understanding of gases involved in respiration and photosynthesis.
What is fixed air sign?
"Fixed air" refers to the astrological sign of Aquarius, which is an air sign. Aquarius is considered fixed because it occurs during the middle of a season and is associated with characteristics such as being determined, stable, and focused.
What trait did priestley exhibit when he shared with lavoisier's about the perfect air?
Joseph Priestley and Antoine-Laurent de Lavoisier were chemists during the 18th century. They got the credit regarding the isolation of oxygen in its gaseous state. They both have a huge influence on both the histories of biology and chemistry.

What is the modern word for the gas produced by a plant to make dephlogisticated air?
Oxygen.
What did Joseph priestly find out dephlogisticated air?
Joseph Priestley discovered that what he called "dephlogisticated air" was in fact oxygen. This discovery challenged the prevailing theory of phlogiston, and laid the foundation for understanding the role of oxygen in combustion and respiration. Priestley's work on oxygen was crucial in the development of modern chemistry.
What is the man recognized Oxygen and hydrogen?
Joseph Priestley was the man who first discovered oxygen, or as he called it "dephlogisticated air", back in the 18th Century
What was the composition of priestley dephlogisticated air and Rutherford's phlogisticated air?
The facts, as they stand, are these: every creature, when respiring, releases phlogiston. In fact, respiration is simply to be considered a form of combustion. Anything that can burn contains phlogiston. Substances, when burnt, release this weightless, invisible substance - an element of their being, their composition - the phlogiston. The phlogiston is always in need of somewhere to go. Such as, air is best for the phlogiston. Air can absorb it. Taking this mode of thinking to its furthest logical conclusion we can only state that the reason creatures "suffocate" is because there is nowhere for the phlogiston to go. When air was removed from around a living creature then there is nowhere for the phlogiston to go and so respiration would cease and the creature dies.
What is dr jospeh blacks theory of respiration?
Dr Joseph blacks theory of respiration was that are air contains fixed air and that when would burns and other things it also produces fixed air. so that was Joseph blacks theory of fixed air
How did Ingenhouze may have collected a sample of dephlogisticated air?

He would have placed aquatic plants in water and exposed them to sunlight, observing the bubbles released during photosynthesis. These bubbles, primarily composed of oxygen, could then be collected and analyzed, allowing him to demonstrate the production of this gas in the presence of light. This experiment contributed to the understanding of the role of plants in oxygen production.

What has no fixed volume and no shape?
Air.
