80% nitrogen 20%oxegen
EDIT
Air is made mostly of Nitrogen (about 80% like stated before) and Oxygen (around 20%, also stated before). However, there is about one percent "Other Gases" such as Carbon Dioxide and Helium.
sublimation The vapor from the dry ice will extinguish the flame from the candle.
You can see dry ice fog even though carbon dioxide is invisible due to water vapor. The visible fog is from ambient water vapor that is condensed by the extreme cold of dry ice. Without plenty of ambient water vapor, the fog output of dry ice is reduced. This is another reason why dry ice foggers often involve hot water.
A fog of water vapour.The dry ice boils away as invisible carbon dioxide and as it does it freezes the water vapour rising off the water surface to make a mist
rock, ice and gas!!
The air around the beaker is cooled by the intense cold of the dry ice, causing water vapor in the air to condense and freeze on the surface of the beaker. This results in the formation of ice on the outside of the beaker.

sublimation The vapor from the dry ice will extinguish the flame from the candle.
The dry ice dramatically cools the air around it, causing water vapor in the air to form ice crystals.

Yes.
The mist produced by dry ice is actually carbon dioxide gas. When dry ice (solid carbon dioxide) sublimates, it transitions directly from a solid to a gas, creating the cloudy mist effect.
