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
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.
How long will it take 10.0ml of nitrogen gas to enfuse through a porius barrier if it has been observed that 92.1 minutes are required for 10.0mL of Cl2 gas to enfuse through the same barrier?
The rate of gas diffusion through a porous barrier is inversely proportional to the square root of its molar mass (that is, a gas four times as heavy diffuses half as fast). The rest is simple arithmetic.
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%.
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.
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).
Under the same conditions of temperature and pressure how many times faster will hydrogen effuse compared to carbon dioxide?
Hydrogen will effuse approximately four times faster than carbon dioxide under the same conditions of temperature and pressure. This is because effusion rate is inversely proportional to the square root of molar mass, and hydrogen has a much lower molar mass than carbon dioxide.
What gas is more abundant nitrogen or oxygen?
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
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).
How fast does hydrogen effuse?
Rms= sqrt(((3)(8.314)(273.15k))/(1g/mole)) = 82.54 is the speed of one hydrogen molecule. Assuming stp
How much faster do ammonia molecules effuse than carbon monoxide molecules?
Effusion goes as the inverse square root of the molecular weight (Graham's Law). The rest is simple algebra.
What gas is almost four times less than nitrogen?
oxygen
What gas effuses four times as fast as oxygen?
Helium is a gas that effuses four times faster than oxygen. This is because helium has a lower molar mass compared to oxygen, leading to faster effusion rates as per Graham's law of effusion.
The air we breathe is mostly a mixture of oxygen and nitrogen in the air is four times greater than the amount of oxygen which of these two elements is the lighter?
Nitrogen is lighter than oxygen. Nitrogen gas (N2) has a molar mass of 28.02 g/mol, while oxygen gas (O2) has a molar mass of 32.00 g/mol. Since nitrogen is lighter, it makes up a larger portion of the atmosphere.
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 molecular weight of a gas that diffuses 1.414 times faster than a nitrogen molecule?
The rate of diffusion of a gas is inversely proportional to the square root of its molecular weight according to Graham's law. Since the gas diffuses 1.414 times faster than nitrogen, its molecular weight must be approximately 1.414 times smaller than that of nitrogen, which is approximately 28 g/mol. Therefore, the molecular weight of the gas is around 19.8 g/mol.
