What is 20 percent of what we breathe everyday?
About 20 percent of the air we breathe consists of oxygen. The Earth's atmosphere is composed of approximately 78 percent nitrogen, 21 percent oxygen, and trace amounts of other gases. This oxygen is essential for human and animal respiration, supporting life by allowing cells to produce energy.
What is the Ratio of different gases in air?
Air is composed of approximately 78% nitrogen, 21% oxygen, and about 1% of other gases, including argon (approximately 0.93%), carbon dioxide (around 0.04%), and trace amounts of other gases like neon, helium, and methane. The dominant gases, nitrogen and oxygen, play crucial roles in supporting life and various atmospheric processes. The composition can vary slightly depending on location and environmental conditions.
What is in 78 percent of air?
Seventy-eight percent of air is composed of nitrogen. Nitrogen is a colorless, odorless gas that plays a crucial role in the Earth's atmosphere. It is relatively inert, which means it doesn't easily react with other substances, making it a stable component of the air we breathe. Oxygen, which makes up about 21% of air, is the second most abundant gas.
What is air made up of?
air is made up of some gases. i.e. it's made up of hydrogen, nitrogen, and mixture of other gases. but the most common is it is made up of nitrogen-78%, oxygen-21%, and other gases-1%air is made up of different gases such as oxygen, carbondioxide, nitrogen and noble gases.
About three-fourths of the air is...gas?
78% nitrogen 20% oxygen and 2% other inert gases.
What percent of the earth's air is oxygen?
The composition of air is usually sated as a dry composition (without water vapour). About 21% is oxygen. The rest is mostly Nitrogen (78%) and Argon (1%). Carbon Dioxide at 300ppm is the next largest with other gases at trace amounts
Where would you find 79 percent nitrogen 16 percent oxygen 4.5 percent carbon dioxide?
Those percentages closely match the composition of Earth's atmosphere at sea level. The atmosphere is made up of mostly nitrogen (around 78%) and oxygen (around 21%), with trace amounts of other gases like carbon dioxide (around 0.04%).
What is the chemical composition of earth?
The earth is actually composed of a total of 90 chemical elements. 81 of them have at least one stable isotope.
The atmosphere is almost 80 percent what?
Nitrogen, with oxygen making up most of the remaining 20 percent. Other gases such as argon, carbon dioxide, and trace amounts of other gases make up the rest of the Earth's atmosphere.
When 99 percent of the atmosphere is made up of either oxygen or?
The percentage of atmospheric gases are:- 79% ; Nitrogen (N2) 20% ; Oxygen (O2) 1% ; ALL other gases, which includes , Carbon Dioxide, Water vapour, The Noble Gases, Sulphur dioxide, Ammonia, Ozone(an allotrope of oxygen) and nitrogen oxides.
What is the percent composition of the gas on earth?
The atmospheric gas of Earth consists of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.03 percent carbon dioxide, with hydrogen, water, ozone, neon, helium, krypton, xenon, and traces of other elements making up the remaining 0.07 percent.
What is composition of clean air?
Approximately 79% nitrogen and 21% oxygen I thing more accurately it is more like 20.5% oxygen, and the rest is nitrogen and other gasses. Carbon dioxide only makes up around 0.03% of the air
What is th second most common gas found in the air we breathe?
This gas is oxygen - 20,946 %.
What is the composition of the atmoshere?
we have 21% of oxygen , 78% of nitrogen and 1% of the other gases and that's what make the earth's atmoshere by: nadia
78 percent nitrogen 21 percent oxygen 1 percent other?
0.93% argon, 0.04% carbon dioxide, and small amounts of other gases including water vapor.
What is the earth atmosphere mostly made up of?
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.
Is the moon composition similar to the composition of the Earth's crust?
The moon's crust composition is similar to the Earth's, but the moon's mantle contains a higher amount of iron. While the moon's crust is composed of 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, and trace amounts of other elements. The Earth's crust is made up of 46.6 percent oxygen, 27.7 percent silicon, 8.1 percent aluminum, 5.1 percent of iron, 2.1 percent magnesium, and other elements.
