it is heavier
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
Dry air is heavier than wet air because water vapor is less dense than the other components of dry air, such as nitrogen and oxygen. When moisture is added to the air, it displaces some of the heavier components, making wet air less dense and therefore lighter.
Helium is lighter (less dense) than oxygen & nitrogen.
Oxygen o2 only is slighty heavyer than air. o3(ozone) is around the same weight as o2 ,but the ozone layer is at a hiegher altitude because it is created when o2 come in contact with high amounts of UV rays.
Helium is less dense than oxygen and nitrogen. Helium is the second lightest and least dense gas, while oxygen and nitrogen are heavier gases. This is why helium is often used to lift balloons, as it is less dense than the surrounding air.
If "heavier than" in the question is interpreted to mean "has an atomic mass greater than", the answer is nitrogen
Gases that are heavier than oxygen include nitrogen, argon, krypton, xenon, and radon. These gases have greater atomic or molecular weights than oxygen, making them heavier.
Oxygen gas is considered heavier than other gases (like nitrogen and helium) because the oxygen molecule (O2) has a higher molecular weight due to its two oxygen atoms bonded together. This higher molecular weight causes oxygen gas to be denser and therefore heavier than some other gases.
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
The rate of effusion of nitrogen is slightly lower than that of oxygen due to nitrogen being a slightly heavier molecule than oxygen. This is based on Graham's law, which states that the rate of effusion is inversely proportional to the square root of the molar mass of the gas.
No. The atmosphere is roughly 80% N2, 20% O2, and about 1% of other trace gases. The molecular mass of N2 is about 28, the molecular mass of O2 is about 32. So, no O2 is not lighter than air, it is slightly heavier.
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.
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
nitrogen is lighter than oxygen
Dry air is about 80% nitrogen. The remaining 20% consists mostly of things that are heavier than nitrogen, so dry air is very slightly heavier than nitrogen.
oxygen is used by human and animals for respiration bt nitrogen do not. for consuming nitrogen plants need nitrogen fixation ths occurs on low scale on other hand oxygen is directly used so its cunsumbtion is more then nitrogen. another important point is that oxygen is used in burning, formation of water etc ths means ratio of cunsumbtion of oxygen is mor then nitrogen
No, nitrogen is not denser than air. Both nitrogen and oxygen are components of air, with nitrogen making up about 78% of the atmosphere. Therefore, the density of nitrogen in the atmosphere is similar to the overall density of air.
