Title: DRY ICE CHEMISTRY
jaysdude09 - October 31, 2006 10:50 PM (GMT)
why does the water steam up when you drop dry ice( CO2) in water??

because it reacts with the H2O molecules

can you explain with details please?

solid CO2 sublimates into CO2 gas
sublimates: changing from solid form directly to gas form.(it doesnt go through the liquid phase)
there is no reaction between the CO2 and water, but a transfer of energy

what do you mean? like the solid CO2 getting heated by room temperature?

energy(heat) always transfers from hot to cool. the CO2(s) is getting energy from the water in order the the system to reach an equilibrium in terms of temperature

so your saying that the heat temperature from the water if getting shifted to the CO2(s) so that they can both be in equilibrium in temperature?

and is....
H20+CO2(s)---> H2CO3
Is H2CO3 the steam that comes out or what?

He says school is more important then GFX, forums ect. Thats tells you itself.

no reaction...just transfer of energy
it's not steam that comes out, it's carbon dioxide gas
H2CO3 (carbonic acid) naturally goes back to being carbon dioxide and water...(however, that is not a product of this reaction as no reaction occurs between the water and the carbon dioxide.

if you notice, i only answer the chemistry questions that are posted, as i am a chemistry major.

Well, you still kick ass.

When you place dry ice into some warm or hot water, clouds of white fog are created. This white fog is condensed water vapor, mixed in with the invisible CO2. The extreme cold causes the water vapor to condense into clouds. The fog is heavy, being carried by the CO2, and will settle to the bottom of a container, and can be poured. You can produce enough ground - hugging fog to fill a medium sized room with a pound or so of dry ice. Do not allow anyone to lay down in this fog, or allow babies or pets into it, as CO2 gas does not support life. Dry ice fog allows low powered laser beams to be seen.

| Producing "dry ice fog" for special effects. When dry ice is put into contact with water, the frozen carbon dioxide sublimates into a mixture of cold carbon dioxide gas and cold humid air. This causes condensation and the formation of fog; see fog machine. The use of warm water speeds up sublimation and leads to more vigorous production of fog. |
