Oxygen in the air is continually replenished through photosynthesis, the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into oxygen. This process occurs in green plants during the daytime. Additionally, the natural movement of air, as well as weather patterns like wind and rain, help distribute and mix oxygen throughout the atmosphere.

Is oxygen part of the air?
No. Oxygen is an element that typically comes in the form of O2. Air is a mixture of gasses and Oxygen is just one of them. Air is about 21% oxygen and 78% nitrogen with another 1% being a variety of other gasses.
What type of hazard occures when the oxygen in the air or blood is replaced by a different substance denying living organisms the oxygen they need?
The hazard that occurs when oxygen is replaced by a different substance is called asphyxiation. Asphyxiation can lead to a lack of oxygen supply to the body's tissues and organs, potentially resulting in suffocation, unconsciousness, and even death.
What do substances react with in the air when they are burning?
Substances primarily react with oxygen in the air when they are burning. This reaction generates heat and light, releasing carbon dioxide and water vapor as byproducts. Additional reactions with nitrogen and other elements in the air can also occur depending on the composition of the substance being burned.
What is the product formed when Oxygen burns in air?
Oxygen can not burn in air.
What percentage of oxygen is in inspired air?
About 21% of inspired air is oxygen.
How is oxygen in air replaced?
Oxygen in the air is constantly replenished through the process of photosynthesis, where plants take in carbon dioxide and release oxygen. This cycle helps maintain the balance of oxygen in the atmosphere.
How carbon dioxide control fire?
3 elements are needed for a fire: fuel, oxygen (air), and heat. The carbon dioxide is used to displace the oxygen being used in a fire. Since fire has no more oxygen available because it is replaced by the carbon dioxide, the fire will go out.
What is replaced as quickly as it is used?
Nonrenewable natural resources are being used faster than they are being replaced.

What useful substance in the air do human being used?
oxygen
What type of hazard occurs went the oxygen in the air or blood is replaced by a different substance denying living organisms the oxygen they need?
Asphyxiation hazard occurs when oxygen in the air or blood is replaced by a different substance, depriving living organisms of the oxygen they need to survive. This can lead to suffocation, unconsciousness, and potentially death if the oxygen supply is not restored promptly. It is important to ensure proper ventilation and monitor oxygen levels in enclosed spaces to prevent this hazard.
How can carbon dioxide be removed from the air and replaced by oxygen gas in submarine?
They use a 'gas exchange system' - usually chemicals that split the carbon dioxide molecules into atoms of oxygen and carbon. The oxygen is recycled back into the air in the submarine, and the carbon is retained for disposal.
If both the idler air sensor and the oxygen sensor shows malfunctioning which should be replaced first on a ford contour 95?
First, change the oxygen sensor and the air filter. Clear the codes and see if the idler air sensor code comes back.

Toilet bowl water rises high when flushing?
because water is being put into pipe which has air and the water that has replaced the air is on top of the air .
Why is compressed oxygen used instead of compressed air in space?
Compressed oxygen is used in space because astronauts can breathe it directly. Compressed air contains other gases like nitrogen, which can cause decompression sickness in space. Using compressed oxygen ensures that astronauts have a pure, breathable gas supply without the risk of introducing other gases that could be harmful.
