The air that we breathe in 78% nitrogen, 21% oxygen, and 1% carbon dioxide, water vapor, and other gases. We only need the oxygen though, so we breathe out the other gases with the carbon dioxide that our body produces during respiration.
So to answer your question, it is nitrogen, but we breathe it in and then out- we don't use it. The only gas we use is oxygen to breathe.
Mostly Carbon Dioxide and Nitrogen, but there are traces of other gasses as well, such as Argon, Carbon Monoxide, and Oxygen.
No. The atmosphere of Venus is mostly carbon dioxide with some nitrogen and trace amounts of other gasses.
95% carbon dioxide, 3% nitrogen, 1.6% argon, and contains traces of oxygen and water.
The atmosphere on Mars is composed mostly of carbon dioxide (about 95.32%), with traces of nitrogen (2.6%) and argon (1.9%). There are also small amounts of oxygen, carbon monoxide, methane, and water vapor.
Pluto's atmosphere consists mostly of nitrogen, but also contains carbon-dioxide and methane.
No, air is mostly nitrogen and oxygen with very very little carbon dioxide (less than 1%)What you exhale is mostly nitrogen, oxygen, and some carbon dioxide.
It's mostly carbon dioxide and a little nitrogen. We need oxygen and a lot of nitrogen.
I think mostly oxygen, and some nitrogen. Also, some carbon dioxide.
Mostly nitrogen, oxygen, and carbon dioxide.
Mostly Carbon Dioxide and Nitrogen, but there are traces of other gasses as well, such as Argon, Carbon Monoxide, and Oxygen.
The air we breathe is mostly made up of nitrogen and oxygen. The remaining 1% is made up of argon, carbon dioxide and other trace gases. Even water vapor (water in its gaseous state) is present in air in varying amounts.
You breathe in air, which is comprised mostly of nitrogen (though the oxygen is what you're after).The oxygen is absorbed into the blood, and stored in red blood cells, which contain hemoglobin.The oxygen in your lungs is thus replaced mainly by carbon dioxide, which is a metabolic waste product, and this is what you breathe out.
you breathe in more nitrogen then oxygen because there is 78% n in the air and 21% o in the air
It is mostly carbon dioxide, 97 %, at a pressure 90 times that of earth's atmosphere at sea level.
No. The atmosphere of Venus is mostly carbon dioxide with some nitrogen and trace amounts of other gasses.
Mostly (about 98%) by Carbon Dioxide, Nitrogen, Argon.
95% carbon dioxide, 3% nitrogen, 1.6% argon, and contains traces of oxygen and water.
