Hydrogen sulfide is very slightly heavier than air. The average molecular weight of air is around 29 grams per mole; H2S is 34 g/mole!

What gas CH4 OR H2S heavier?

H2S (hydrogen sulfide) is heavier than CH4 (methane) because the molar mass of sulfur (S) is greater than the molar mass of carbon (C). This difference in molar masses results in hydrogen sulfide being denser and therefore heavier than methane.


Why heavier h2s?

Hydrogen sulfide is a chemical compound with the formula H2S. It is colorless gas with the characteristic foul odor of rotten eggs. H2S is heavier than air, very poisonous, corrosive, flammable and explosive.


Is nitrogen heavier than oxygen?

it is heavier


What is heavier nitrogen or helium?

Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).


Who is heaver nitrogen or air?

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.


Is H2S the heaviest gas?

No, remember any element heated to a high enough temperature will form a gaseous phase for instance mercury vapour would be heavier than H2S.


Is ammonia vapor heavier than nitrogen?

Yes, ammonia vapor is heavier than nitrogen. The molecular weight of ammonia (NH3) is 17 grams per mole, while nitrogen (N2) has a molecular weight of 28 grams per mole. This difference in molecular weight causes ammonia vapor to be denser and heavier than nitrogen gas.


Which element is heavier than carbon but lighter than oxygen?

If "heavier than" in the question is interpreted to mean "has an atomic mass greater than", the answer is nitrogen


Which is heavier hydrogen or nitrogen?

Nitrogen, has a atomic weight roughly 14 times heavier then that of hydrogen.


Why atmospheric nitrogen is heavier than chemical nitrogen?

Atmospheric nitrogen is composed of two nitrogen atoms bonded together (N2), while chemical nitrogen can refer to various compounds involving nitrogen, such as ammonia (NH3) or nitrate (NO3-). The molecular weight of N2 is heavier than individual nitrogen atoms found in chemical compounds, leading to atmospheric nitrogen being heavier.


Why is fluorine heavier than nitrogen?

Fluorine is heavier than nitrogen because fluorine has more protons and neutrons in its atomic structure compared to nitrogen. The atomic mass of fluorine is approximately 19 amu, while the atomic mass of nitrogen is approximately 14 amu. Additionally, fluorine is located in a higher period (row) on the periodic table compared to nitrogen, which contributes to its heavier weight.


Which gasses are heavier than oxygen?

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.
