When the universe came into existence, the only elements were mainly hydrogen and helium. Some time afterwards, stars formed and started to burn hydrogen in a nuclear furnace. As this happens the hydrogen combines to form helium. This is the process which occurs in our own sun that is also just a star. As the sun and other stars run out of hydrogen the core collapses, the temperature increases and helium starts to burn to form heavier elements. Small stars form red giants and then simply fade away but if the star is large enough they go out with a bang called a supernova. This returns a lot of the star's mass to the universe in the form of larger atoms before the remainder forms and falls into a black hole. Some time later when new stars form and planets form around them, they contain these heavier elements remnants of earlier stars. All of the heavier elements on earth had their origins is such supernova stars. Nitrogen is the largest component of the atmosphere. Phosphorus is mined as phosphate.
Nitrogen gas makes up about 78% of Earth's atmosphere today. However, human activities have altered the nitrogen cycle by increasing the amount of reactive nitrogen in the environment through processes like fertilizer use and fossil fuel combustion, which can lead to environmental issues like air and water pollution.
Yes, nitrogen dioxide is considered an air pollutant.
The nitrogen used in the Haber process is sourced from the air through a process called air separation. The hydrogen used in the Haber process is typically produced through the steam reforming of natural gas or through water electrolysis. Both nitrogen and hydrogen are essential for the synthesis of ammonia in the Haber process.
The air is made up, mostly, of oxygen and nitrogen.. Air is 78 % nitrogen, 21 % oxygen, about 1 % argon, and a whole raft of other gases present in even smaller amounts..
In 500L of dry air, 78% is nitrogen. To find the volume of nitrogen, you would use 0.78 x 500L = 390L of nitrogen in the 500L of dry air.
The nitrogen in today's air primarily comes from the atmosphere's original composition, which was formed during the Earth's early history by volcanic activity and meteorite impacts. Over time, nitrogen-fixing bacteria in soil and water have also played a significant role in converting atmospheric nitrogen into forms that can be utilized by living organisms.
Approximately 78% of the Earth's atmosphere is composed of nitrogen.
Sulfur oxides and nitrogen oxides in the air primarily come from the burning of fossil fuels in vehicles, power plants, and industrial processes. When fuel containing sulfur and nitrogen is burned, these elements combine with oxygen in the air to form sulfur oxides (SOx) and nitrogen oxides (NOx), which are then released into the atmosphere.
Nitrogen doesn't contain air, but the air contains Nitrogen.
Our air is about 79% Nitrogen.
Yes. About 75% of air is Nitrogen.
About 78% of air is Nitrogen.
There is about 78.09% of nitrogen in the air.
Nitrogen in the air comes from two main sources: volcanic activity and biological processes. Volcanic eruptions release nitrogen into the atmosphere, while living organisms and certain bacteria convert nitrogen from the soil into a form that can be used by plants, which then release it back into the air through processes like respiration and decay.
