No. Oxygen and Nitrogen molecules are not the same size. China has a railroad that rides along at 20,000 feet in Tibet. They pump air into the cars. The cars have filters. Nitrogen gas leaves through the filters and oxygen remains in the railroad cars. By using simple pumps and filters they increase the amount of oxygen in the cars. If oxygen and nitrogen were the same size, it would not work.
What else can I help you with?
Does oxygen and nitrogen weigh the same in volume?
No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2 So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.
Does nitrogen and oxygen weigh the same?
No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2 So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
The percentage of nitrogen in the air remains constant when you inhale and exhale because the body does not use nitrogen during respiration. While we inhale oxygen and exhale carbon dioxide, the nitrogen in the air is not chemically altered or metabolized by the body's processes.
What is the ratio for oxgyen with same mass of nitrogen?
Atomic mass ratio for O : N is 15.9994  : 14.0067 .So it takes 14.0067/15.9994 moles of Oxygen to have the same mass as one mole of nitrogen. This is valuated at 0.8754516 to 1.00000
What mass of oxygen contain same number of molecule as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
Does oxygen and nitrogen weigh the same in volume?
No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2 So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.
If you breathe in pure nitrogen what will happen?
Nitrogen is an inert gas. over 70% of the air you are breathing right now is nitrogen, so nothing. Breathing pure nitrogen would be bad only because theres no oxygen in it. breathing pure nitrogen you would lose conciousness from lack of oxygen within seconds and eventually die, because your organism has no use for it and it's same as breathing nothing and dying because of lack of oxygen.
Equal volumes of nitrogen and oxygen at the same temperature and pressure would?
If equal volumes of nitrogen and oxygen are at the same temperature and pressure, then both (the nitrogen and oxygen) will contain the same number of particles
Weight of a given volume of pure vapor or gas compared to the weight of an equal volume of dry air at the same temperature and volume?
PV = nRTAt a given temperature (T), pressure (P), and volume (V), the number of moles of gas is constant. Thus, whichever gas has a higher molar mass will weigh more. Air is composed of mostly Nitrogen gas (N2), Carbon Dioxide (CO2) and Oxygen gas (O2). The molar masses of these are 28, 44, and 32 respectively.If the pure vapor or gas in question is water vapor (H2O), with molar mass 18, then the air will weigh more.
Does nitrogen and oxygen weigh the same?
No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2 So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
The percentage of nitrogen in the air remains constant when you inhale and exhale because the body does not use nitrogen during respiration. While we inhale oxygen and exhale carbon dioxide, the nitrogen in the air is not chemically altered or metabolized by the body's processes.
Which gas is heavier oxygen or nitrogen?
Since both form diatomic elements, we simply have to compare molecular masses. O2 has a mass 32.0 g/mol, while N2 is 28.0 g/mol. This means that, since gases (according to the ideal gas law) all contain 22.4 mol/L, then the same volume of oxygen would be heavier than the same volume of nitrogen.
The gases in a mixture have the following partial pressures at the same volume and temperature 1013000 Pa nitrogen 700 mm argon 1.20 ATM of helium 790 torr oxygen and 0.50 ATM of carbon dioxide?
Carbon dioxide Argon Oxygen Helium Nitrogen
All samples of pure water have the same mass?
Yes, all samples of pure water have the same mass because the mass of water is determined by its chemical composition, which consists of two hydrogen atoms and one oxygen atom. This means that regardless of the volume or container, the mass of pure water remains constant.
Is oxygen and nitrogen has same numbers of protons?
Oxygen has 8 protons and Nitrogen has 7 protons the atomic number of an element which tell you how many protons an atom has is the lower one seen on each element on the periodic table.
Does all pure water have the same mass and volume?
No.
Are fruits elements?
An element is a pure substance of the same atom that cannot be divided into smaller components.A fruit is made of different atoms (carbon, nitrogen, oxygen, etc.) so it is not an element
