Given that a helium balloon weighs more in a vacuum chamber on earth than in the earth's atmosphere would a rock weigh more in a vacuum chamber on earth than in the earth's atmosphere?

Yes. Any material object in a fluid is "buoyed" up by a force equal to the weight of the fluid it displaces.
In air, the weight of the rock is reduced by an amount equal to the weight of the air that would otherwise occupy the rock's volume if the rock were not there.

What happens when a helium-filled balloon is released and rises into the atmosphere?
It pops
Why don't normal balloons stay in the sky?
Due to the weight of the balloon. A balloon is merely a capsule full of air so it will fall to the ground as the balloon weighs it down. A helium balloon will rise into the air because helium is less dense than normal air (i.e. it weighs less). The air inside the balloon is the same density as the air outside. The balloon material itself is heavier than air, which causes the balloon to sink. If you decrease the density of the trapped air, such as by heating it or replacing it with hydrogen or helium, the balloon may become even lighter than the balloon material and an equal volume of normal air, in which case the balloon will float or rise.
Will a lit cigarette ignite a helium balloon?
Helium is not flammable. However, the cigarette might puncture the balloon.
Can a lead balloon float?
No... it wouldn't even survive the conditions of the upper atmosphere, unless it was a very tough balloon.. even if it could I'm assuming eventually the atmosphere would reduce to a point where it was as dense as helium or hydrogen (the gas I'm assuming would make your balloon float) and your balloon would stop anyway at a maximum altitude. Either way.. after that, the balloon would have to break away from Earth's gravity (not easy) and then somehow cover 382500km or so to get to the Moon itself..
Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
Reactive gas found in earths atmosphere?
Hydrogen or Helium
Which of these is not one of the primary gase found in earths atmosphere?
helium
What happens when a helium-filled balloon is released and rises into the atmosphere?
It pops
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
Could you use helium to float an item into space?
No, air pressure increases as the balloon goes up, so the balloon will pop and fall to the ground. You can get high up in the atmosphere (but you need a LOT of helium and a balloon that can get VERY big) you will not reach "outer" space beyond the Earth's atmosphere.
Why does a helium-filled balloon rise to a certain altitude in the atmosphere and float there instead of rising further?
the reason is that as the balloon gradually goes up the density of air in the upper atmosphere decreases
What causes pressure inside a balloon?
hylium (***helium) And actuality the pressure is caused by the elasticity of the balloon itself and don't forget the added pressure of our atmosphere
What is the earths atomsphere?
the earth atmosphere is made up of carbon dioxide and oxygen and some helium.
The most abundant inert gas is what?
Argon, in the earths atmoshere Helium in the universe Argon in the earths atmoshere Helium in the universe
If you burst a balloon where would the helium go?
Into the atmosphere. I understand that, being a very light gas, the helium would gradually diffuse into outer space.
Is a helium balloon a solid?
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
Is helium poisenous?
No however the lack of oxygen is deadly. It is unlikely that you will hurt yourself sucking the helium out of balloons, as long as you breathe oxygen in between breaths of helium. There is a small percentage of helium (.0005%) in the earths atmosphere.
