What could happen if there were more oxygen than nitrogen in the atmosphere?

Oxygen is more reactive than Nitrogen. It would definitely increase the greenhouse effect and it would result in greater Global Warming. Atmospheric pressure would change because the mass of oxygen is greater than the mass of nitrogen. Complex Life on earth might become impossible under those conditions.

Does air contains 78\% nitrogen and 21\% oxygen?

Air is mostly gas The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

What is the partial pressure of oxygen and nitrogen in the air if air contains 20\% by volume of oxygen and 80\% by volume of nitrogen?

Calculation of partial pressure of oxygen and nitrogen Total pressure of air in equilibrium with water = 10 atm. As air contains 20\% oxygen and 79 \% nitrogen by volume, Partial pressure of oxygen (PO2) = 2 x 760 mm = 1520 mm Partial pressure of nitrogen ( ) = 7.9 x 760 mm 6004 mm Step-II.

What will happen if the amount of oxygen is increased in the air short answer?

Answer: With the increased levels of oxygen humans would have an increased chance of oxygen toxicity. This happens when humans are exposed to increased oxygen levels than their bodies are normally used to. Over time, this could lead to lung damage, poor eyesight and cells not being able to reproduce.

What are the final partial pressure of nitrogen and oxygen?

Therefore, at sea level, where atmospheric pressure is known to be 760 mm Hg, the partial pressures of the various gases can be estimated to have partial pressures of approximately 593 mm Hg for nitrogen, 160 mm Hg for oxygen, and 7.6 mm Hg for argon.

What is the percentage of oxygen and nitrogen in the air?

Air consists of 21 \% oxygen, 78 \% nitrogen and 1 \% argon by volume. Calculate: * (a) the partial pressures in Pa, if total pressure is 1 atm, * (b) the concentration in mol m–3, of each gas at 273 K, * (c) the average molar mass

What is the ratio of oxygen and nitrogen in the blood?

Air is composed of 78\% nitrogen and 21\% oxygen and both pass into the blood. The lungs pass gases in both directions between blood and air. With nitrogen, the body has no use for it and it remains in the blood your whole life. Once the blood is saturated with nitrogen there is room for no more so the net flow from air to blood is zero.

What is the volume of air required to burn 12g of carbon?

What will be the volume of air required to completely burn 12 g of carbon at STP (air contains 21\% oxygen by volume)? Stoichiometric oxygen requirement for 12 gm of carbon is 12/14* 32 = 27.43 gm. This is equal to 27.43/ 1,430 CM (density is 1.43 kg/ NM^3 and i am ignoring density correction from NTP to STP).

Which substance is found in the air around US?

This substance is oxygen. Oxygen is one of the major components of air around us. Air comprises almost 21\% oxygen. Nitrogen: When you blow over a burning candle you notice that it extinguishes. This means air contains incombustible gases (gases which don’t support combustion) too. This is majorly due to the presence of nitrogen.
