Yes. Air is diatomic nitrogen (N2), diatomic oxygen (O2), some argon...erm... carbon dioxide (CO2)...and a million other trace compounds/elements.
It's roughly 78% N2, 21% O2, 1% Argon. Something like that.
Now, N2 weighs 28 amu (Atomic Mass units. You can see the weights on a Periodic Table, usually to 4 decimal places. Carbon is ~12, Nitrogen is ~14, Oxygen is ~16 and Hydrogen is ~1). And we can see that O2 weighs ~32amu, Argon weighs ~40, I think.
Either way, hydrogen weights only 1 per hydrogen. So diatomic Hydrogen (which is usually what's meant when discussing Hydrogen in this way) is H2 and weighs only 2. It's the smallest element with no neutrons and only 1 proton. The lightest element of all.
So Hydrogen doesn't weigh as much as ANY of air's other constituents, so air as a total must weigh more...which is true for most things vs hydrogen.
This is if both gases, air and hydrogen, are at the same pressure.
What else can I help you with?
A basic gas lighter than air?
Hydrogen gas is a basic gas that is lighter than air. It is commonly used in weather balloons and airships due to its buoyant properties. However, it is highly flammable and must be handled with caution.
How do you know hydrogen gas is lighter than air?
Balloons filled with it float in air
How did the Hindenburg stay in the air?
The gas bags of the Hindenberg were filled with Hydrogen gas. Hydrogen is lighter than air, the same way air is lighter than water. The Hydrogen filled "balloon" floated on the air just as one filled with air would float on water. By letting out gas or replacing it from tanks of compressed Hydrogen, they could control the trim and buoyancy of the airship. Unfortunately, Hydrogen is highly flammable when mixed with air, as we all know from what happened to Hindenberg. Although there are ways to avoid disasters such as the one that befell it, people were afraid and that was, effectively, the end of lighter-than-air transportation for commercial purposes.
What properties make helium useful?
While it is not a "Noble Gas" it is much lighter than air. It is not lighter than Hydrogen, but it does not ignite as easily.
What lighter than air gas was once used to power airships in cause the Hindenburg disaster?
The gas was Hydrogen.
Does hydrogen gas rise in air?
Yes. Hydrogen is a gas, and all gases tend to diffuse. Whether or not air is present is irrelevant.
Helium is a gas which is used in balloons because it is lighter than air.But hydrogen is a gas which is even lighter than the helium.Why helium is used rather than the hydrogen?
Because Hydrogen is highly flammable, and will easily and rapidly burn in the air and turn into H2O (water).
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
Is Hydrogen gas lighter than air or heavier than air?
Hydrogen gas is 16x lighter than air. The atomic weight of Hydrogen is 1 atomic mass unit, and the atomic weight of oxygen is 16 atomic mass units. 602,000,000,000,000,000,000,000 hydrogen molecules would weigh 1 gram. The same amount of oxygen would weigh 16 grams. Clarification: The air we breath is actually a mixture of oxygen, nitrogen, and carbon dioxide. But in this example, I treated it as pure oxygen to keep things simple.
What is used as lifting gas in balloons?
Hydrogen gas makes the ballon lighter than air therefore it drifts upwards
Why a balloon filled with hydrogen gas floats in air?
A balloon filled with hydrogen gas floats in air because hydrogen is lighter than air. The buoyant force acting on the balloon is greater than the gravitational force pulling it down, allowing it to float.
What was the Hindenburg that exploded over Lakehurst May 6 1937?
It was a dirigible- a lighter-than-air airship with a rigid frame. It was lighter than air since it was filled with hydrogen gas. Unfortunately hydrogen is also extremely flammable.
