Which is heavier hydrogen or nitrogen?
Nitrogen, has a atomic weight roughly 14 times heavier then that of hydrogen.
Why has the nitrogen level in the atmosphere kept constant over time?
The absolute amount of nitrogen in the atmosphere has kept constant over time because it is not a gas that reacts readily with other elements - it is relatively inert. However, the relative level of nitrogen in Earth's atmosphere has changed over time as the atmosphere was "terraformed" by the life evolving on the planet. For instance in the Cretaceous times the atmosphere was much richer in Oxygen (30%) than today (20%) which means that then the %Nitrogen was 70% rather than 80%.
How many meters cubed of nitrogen gas can 1 liter of liquid nitrogen produce?
Since a gallon is actually a measure of volume, the information about the liquid oxygen is not needed. 1 gallon = 0.134 cubic feet.
What are the five most abundant elements in earth's atmosphere?
The five most abundant elements that make up atomic matter are; Hydrogen, Helium, Oxygen, Carbon and Neon. Hydrogen is by far the most abundant element. There is three times as much Hydrogen than the next most abundant element, Helium.
What is the oxidation for nitrogen in nitric oxide?
1 because oxygen is -2 so then N must be 2 divided by two =1 N2O 2(N) + (-2) = 0 2 times N (the unknown) + the oxidation number of oxygen = 0 because its a neutral compound so 2N = 2 N=2/2 = +1
Under the same conditions of temperature and pressure how many times faster will hydrogen effuse compared to carbon dioxide?
nearly 3 times faster i think well that's what it said in the chem book
What gas is more abundant nitrogen or oxygen?
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
How many times more than oxygen makes up air?
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).
How many Time more nitrogen than oxygen make up air?
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).
What is an element that is 3 times greater than the oxygen?
nitrogen
What gas is almost four times less than nitrogen?
oxygen
What is the molecular weight of a gas that diffuses 1.414 times faster than a nitrogen molecule?
14 g/mole
What happens to the oxygen when you excercise?
You heart beats faster and some times you carnt keep up with it so you have to slow down
What is the function of nitrogen in a gas tank?
The nitrogen moderates combustion and your breathing. Pure oxygen is not good for you if taken too long. The heart beats are driven by nitric oxide. The Sunday times produced a joke cartoon of gentlemen of the road living healthily under the motor way bridge many years ago when it was discovered.. This planet sits on a balance of 79% nitrogen and 20% oxygen. If the oxygen level were to get to 23% we would spontaneously ignite from the sun. Nitrogen is a stable inert gas, yet reactive enough in lightning conditions to oxidise and produce the nitrogen oxide that is a source of subsequent nitrates. At normal pressures nitrogen oxygen ratio is fine but divers have to be careful when ascending too quickly from the depths as "the bends" will occur and nitrogen gets released by diffusion especially at the joints.
Is oxygen gas heavy than air?
On average, oxygen (O2 which is 2 oxygen atoms) makes up about 20-21% of air. The bulk of the rest of it is Nitrogen (N2 which is 2 nitrogen atoms) (about 78%).Oxygen has a molecular weight of about 16 per atom. Nitrogen has a molecular weight of about 14 per atom. Pure Oxygen gas is thus heavier than "air."For example:Say you had a sample of air containing 8 Nitrogen atoms and 2 Oxygen atoms (80% N2, 20% O2). Based on atomic weight, it would come in at 150. (150 is calculated by multiplying the 8 nitrogen atoms by = 112, and then multiplying the 2 oxygen atoms by 16 = 32, and adding 112 and 32 together = 150).If you had the same amount of pure oxygen gas (O2), you would have 10 oxygen atoms times 16 = 160.So as a rough approximation, if the weights of oxygen gas = 160 and air = 150, air is approximately 93.75% the weigh of oxygen gas.. or in other words, "air" is approximately 6.25% lighter than pure oxygen gas.
What is in the air at all times?
Air is approximately 20% oxygen, 79% nitrogen and a mixture of argon, other inert gases, methane, carbon dioxide and ozone.
What are marine applications for helium?
As breathing gas for diving: A mixture of oxygen and helium (some times containing nitrogen or a small percentage of oxygen) is used to avoid the phenomenon of narcosis when only pure oxygen is used; also helium make the effort for breathing easier.
