Earth, with roughly 78%.
No, the ideal ratio of oxygen to nitrogen in the air is already balanced to support human life. Increasing the oxygen concentration can be harmful as it may lead to oxygen toxicity, while decreasing the nitrogen concentration can lead to nitrogen narcosis.
The concentration of nitrogen dioxide in the air can vary depending on the location and time of day. In urban areas with high traffic or industrial activity, levels may be higher. However, the average concentration of nitrogen dioxide in outdoor air is typically around 20 parts per billion (ppb).
Nitrogen makes up about 78% of the Earth's atmosphere in the homosphere (the lower atmosphere where gases are well-mixed). This high concentration remains fairly constant throughout the homosphere.
Nitrogen inhibits the combustion process by diluting the oxygen concentration in a closed environment. When nitrogen is introduced to an environment with high oxygen levels, such as in fire prevention systems, it displaces the oxygen and reduces the possibility of combustion. This process is known as nitrogen blanketing or inerting.
The Dumas method is used to determine the nitrogen content in organic compounds. It involves combustion of the sample at high temperatures to convert the nitrogen into nitrogen gas, which is then collected and measured. By knowing the mass of the sample and the amount of nitrogen gas produced, the nitrogen content of the original compound can be calculated.
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
Uranus.
The lowest concentration of nitrogen can be found in the urine when it is first produced. As it accumulates in the bladder, so does the overall concentration of nitrogen.
Both compounds are toxic and can be lethal at high concentration.
No, the ideal ratio of oxygen to nitrogen in the air is already balanced to support human life. Increasing the oxygen concentration can be harmful as it may lead to oxygen toxicity, while decreasing the nitrogen concentration can lead to nitrogen narcosis.
Planet Earth - about 80%.
Nitrogen plant burns are caused when to much fertilizer (or fertilizer with a high concentration of Nitrogen) is added to a plant. If the concentration of Nitrogen (or Nitrogen compounds such as ammonia) is to high it causes the soil to become highly acidic in the area where it was applied, the high acidity damages (or kills) the roots of the plant retarding or preventing the uptake of water or nutrients by the plant.
The concentration of nitrogen dioxide in the air can vary depending on the location and time of day. In urban areas with high traffic or industrial activity, levels may be higher. However, the average concentration of nitrogen dioxide in outdoor air is typically around 20 parts per billion (ppb).
Assuming you mean a concentration of 0.023 as a mole fraction... 0.023 is equivalent to 23000 ppm
The greatest concentration of nitrogen on the Earth is found in its atmosphere. The atmosphere is approximately 78 percent nitrogen.
