Why is carbon dioxide in dry ice?

Answer 1

Dry ice is simply CO2(s), carbon is able to form molecular bonds only when the kinetic energy of the electrons approaches zero, (London Dispersion Force) hence the cold temperature of dry ice.

Answer 2

Most photosynthetic plants use it in the process of cell-respiration - they break down the molecule(s) with the water produced in PS, and use one carbon and oxygen as energy to break down the sugar they produce during PS, finally releasing the extra oxygen back into the environment. This is fortunate, as we breathe oxygen and release CO2, which the plants then use to break down their 'meal' of sugars.

If you want commercial uses...

Most life-jackets are filled with CO2, which allows for quick-deflation.

The soda you drink contains CO2, creating the bubbly fizz.

CO2 is used in the production of dry ice, which is either a halloween decoration, or a big chunk of ice that burns you if you touch it. -Shrug-

Answer 3

Carbon dioxide is in dry ice because it undergoes sublimation, where it transitions directly from a solid to a gas at temperatures below -78.5 degrees Celsius (-109.3 degrees Fahrenheit) without melting into a liquid state. This unique property allows solid carbon dioxide to turn into gas, creating the "smoky" effect that is often observed when dry ice is used.

Answer 4

Baking: the release of carbon dioxide from sodium hydrogen carbonate expand the material.

Dry ice: solid carbon dioxide has a melting (sublimation) point of -78 0C.

Answer 5

It is used by sticking it up your bum hole and then licking it and then put it on your food.

Answer 6

Dry ice IS carbon dioxide, in solid form.
