Air, you dont breathe out pure CO2
it is not gas it is just air
No. helium is released in outer air but does not lose or change its chemical formula
Seltzer water contain carbon dioxide; bubble water may contain and another gases, including air.
Ninety-nine percent of the atmosphere is already filled with nitrogen and oxygen, and carbon dioxide makes up less that 1% of the rest. So it will take a long time for the air to fill up with carbon dioxide.
It can, if you fill the balloon with air and let it float on the carbon dioxide. We used to do this with soap bubbles to illustrate certain effects of surface tension (for example, the fact that bubbles of the same size form a planar interface, but the interface between bubbles of different sizes bulges towards the larger bubble, proving the pressure in the smaller one is higher... it's much easier to see this when the bubble isn't actively falling towards the floor as you're trying to observe it). Put a piece of dry ice in the bottom of a large bath jar, and allow the bubbles to float on the denser carbon dioxide layer in the jar. Filling a balloon with carbon dioxide, though, will not cause it to float, as carbon dioxide is denser than air.
It is not common to fill blimps with carbon dioxide because it is not as buoyant as helium, which is the most common gas used to fill blimps. Carbon dioxide is heavier than air and could affect the lift and stability of the blimp. Additionally, carbon dioxide is flammable and can be dangerous if not handled properly.
Dry ice is frozen carbon dioxide. Sublimated carbon dioxide is heavier than room air and will not float.
The balloon filled with air will float to the ceiling in a room filled with carbon dioxide. This is because the density of carbon dioxide is greater than the density of air. The balloon will experience a buoyant force upwards due to the density difference, causing it to rise towards the ceiling.
One of my favorites is to get a big bath jar and put dry ice in the bottom. Cover it (loosely) to keep air from stirring it up and let some of the dry ice evaporate. IF carbon dioxide is heavier than air, the carbon dioxide will fill the bottom of the bath, and you can float a soap bubble filled with ordinary air on the heavier carbon dioxide layer. Try it and see.You could also construct an apparatus with candles at various heights and connect it with tubing to a carbon dioxide source (such as a compressed gas cylinder). As the carbon dioxide enters the tank with the candles, it should fill up the tank in such a way that the lowest candles are extinguished first.
The Carbon dioxide molecule is more massive than the other primary gasses in the air, so filling the ball with Carbon dioxide will make it more massive than a ball filled entirely with air at the same pressure and temperature. Even adding an excess of Carbon dioxide to an air-filled ball will add mass.
Carbon dioxide is more dense than air.
do autotrophs remove carbon dioxide from the air
