Which one of the following is heavier than air?

– Now, vapour density for Sulphur dioxide is 32, for nitrogen is 14, carbon monoxide is 14 and ammonia is 8.5. – So, in comparison we can say that Sulphur dioxide has a density more than that of air that is 28.97 g/mol. so, we can say that Sulphur dioxide is heavier than air. The correct answer is option “D” .

Which of the following gas is heaviest?

Radon is the heaviest gas.

• It is a chemical element with the symbol Rn and atomic number 86.
• It is a radioactive, colorless, odorless, tasteless noble gas.
• The atomic weight of Radon is 222 atomic mass units making it the heaviest known gas.
• It is 220 times heavier than the lightest gas, Hydrogen.

Which one among the following gases is heavier than the others?

Other Links Notes: Carbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole. The oxygen in the air is actually O2, or molecular oxygen, with a molecular weight of 32. Hence, carbon dioxide has a higher density, or is heavier than oxygen.

Is hydrogen heavier than air?

Hydrogen gas is lighter than air.

Is hydrogen sulfide heavier than air?

It is flammable, colorless and noticeable by its rotten egg odor. Hydrogen sulfide is heavier than air, so it stays low to the ground. People can smell the specific odor at low concentrations in air ranging from 0.0005 to 0.3 parts per million (ppm).

Which is the lightest gas?

hydrogen gas
Hydrogen is the lightest element of the periodic table, thus, hydrogen gas is the lightest gas. The atomic mass of hydrogen gas (H2) is twice the mass of hydrogen element (H).

Which among the following is heavier than dry air?

We can conclude from the above discussion that moist air and hydrogen sulphide are heavier than dry air.

Is hydrogen more or less dense than air?

But hydrogen is less dense than air, so the air pushes up on the balloon harder than gravity is pulling it down, and the balloon tries to move up! So just like wood float on water, hydrogen balloons float on air. Answer 2: Density is a measure of how much substance per unit volume an object has.

Is ammonia denser than air?

Anhydrous ammonia gas is lighter than air and will rise, so that generally it dissipates and does not settle in low-lying areas. However, in the presence of moisture (such as high relative humidity), the liquefied anhydrous ammonia gas forms vapors that are heavier than air.

Is ammonia heavier than air?
