A mixture of O2 H2 and N2 gases exerts a total pressure of 282 kPa. If the partial pressures of oxygen and hydrogen are 110 kPa and 106 kPa respectively what is the partial pressure of nitrogen?
Total pressure = ppO2 + ppH2 + ppN2ppN2 = Total pressure - (ppO2 + ppH2)ppN2 = 282 kPa - (110+106 kPa) = 282kPa - 216kPappN2 = 66 kPa = partial pressure of nitrogen
What are the 6 most abundant elements in the biosphere?
Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
What does nitrogen have to do with diving?
when you go diving, you take a pressurized tank of air, air consists of about 79% Nitrogen and 21% Oxygen, at normal pressure (atmospheric pressuer) the partial pressure of Nitrogen is 0.79 Bar and Oxygen 0.21 Bar which is safe. Under high pressures (say 5 Bar which is at a depth of about 40 metres) the partial pressure of each gas increases Nitrogen (0.79x5=3.95Bar) which causes the lungs to absorb the nitrogen at a higher rate which influences the nervous system causing Narcosis (As if you're Drunk) The reason why you can't take a tank of oxygen instead of air is that oxygen becomes toxic at higher partial pressures
What is the equation for nitrogen gas plus hydrogen gas under pressure and at high temperature?
the balanced equation is N2 + 3H2 = 2NH3
What is atmospheric air pressure at sea level of nitrogen?
This is a question involving figuring out a partial pressure. As in Dalton's law of partial pressures. (Gotta give the man his props. He earned them.) Without splitting hairs and working things to ten decimals, air pressure at sea level is about 14.7 psi, and N2 makes up about 78% of air. Crunch the numbers and the partial pressure of nitrogen will be a bit under 11.5 psi. To beat this one to death, look up the percentage of nitrogen in the air and the air pressure at sea level to as many decimals as you'd like. Then multiply. Just so you know, John Dalton said that the sum of the partial pressures of gases in a mixture will equal the total pressure of the gas. And that was back in 1801.
. A mixture of oxygen hydrogen and nitrogen gases exerts a total pressure of 282 kPa. If the partial pressures of oxygen and hydrogen are 110 kPa and 106 kPa respectively what is the partial pressure?
Total pressure = ppO2 + ppH2 + ppN2ppN2 = Total pressure - (ppO2 + ppH2)ppN2 = 282 kPa - (110+106 kPa) = 282kPa - 216kPappN2 = 66 kPa = partial pressure of nitrogen

What is the chemical formula when nitrogen gas reacts with hydrogen gas?
Nitrogen and hydrogen react to form ammonia. This is the reaction in the Haber process, in which the gases are mixed at high pressure and moderately high temperature and passed over an iron catalyst.
What is the atmospheric pressure if the partial pressure of nitrogen oxygen and argon are 442mm Hg 118.34mm Hg and 5.66mm Hg respectively?
These three components are the three largest components of air. The total pressure of a gas mixture is just the sum of the partial pressures of each component. Air is a mixture and nitrogen, oxygen, and argon are the three biggest components. So, the atmospheric pressure (or air pressure) would be the sum of the partial pressure of each component of the air: Ptot=PPnitrogen + PPoxygen+ PPargon = 442 mmHg + 118.34 mmHg + 5.66 mmHg = 566 mmHg
What are the 6 most abundant elements in the biosphere?
Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
What are elements composed of compounds atoms mixtures or molecules?
At sufficiently high temperatures and low pressures, all elements are composed of atoms. At standard temperature and pressure, some elements are composed of molecules, usually diatomic molecules, as with nitrogen, hydrogen, oxygen, and all the halogens.
How is ammonia separated from unreacted hydrogen and nitrogen?
When the gases leave the reactor they are hot and at a very high pressure. Ammonia is easily liquefied under pressure as long as it isn't too hot, and so the temperature of the mixture is lowered enough for the ammonia to turn to a liquid. The nitrogen and hydrogen remain as gases even under these high pressures, and can be recycled. Another way is to add the water to the mixture (or pass the mixture from cold water) Ammonia is highly soluble in water but other two gases are not.
What state of matter are helium and hydrogen?
A standard temperature and pressure, they are gasses. However under different temperatures and pressures they can be plasmas, liquids and solids.
Why is the haber process not run at a high pressure?
because in this process a mixture of nitrogen and hydrogen is heated at 400 to 450c
What will be temperature of nitrogen when its pressure is 29-43 psi?
Over that modest range of pressures, Nitrogen gas could have a temperature of anything above approximately 80 degrees Kelvin (minus 193 degrees Celcius).
Do hydrogen nitrogen and oxygen normally occur as single atoms?
With the conditions of temperature and pressure found on the Earth hydrogen and oxygen in their free state are gas molecules consisting of two atoms. But nitrogen gas can also be found in this form.
