Dry ice is solid carbon dioxide, with the formula CO₂. At room temperature, this substance has an interesting property: it doesn't melt, it evaporates. This means that dry ice completely avoids the liquid state, which creates an interesting effect.
How do I make dry ice?
Dry ice is made by liquefying carbon dioxide and injecting it into a holding tank, where it's frozen at a temperature of -109° F and compressed into solid ice. Depending on whether it's created in a pelletizer or a block press, dry ice can then be made into pellets or large blocks.
What is the formula for ice?
Since, ice is a crystalline form of water, so the chemical formula of ice is the same as that of water and the chemical formula of water is \[{H_2}O\].

How long does dry ice last in a Styrofoam cooler?
18-24 hours How Long Does Ice Last in a Styrofoam Cooler? How long your ice stays frozen in a Styrofoam Cooler also depends on the ice type. While dry ice stored in these coolers can last up to 18-24 hours, water ice ideally retains 12-24 hours. Smaller styrofoam coolers cannot hold much ice and have low insulating capabilities.
What is dry ice used in?
Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere).
What is the formula of the limestone?
Limestone consists of calcium carbonate, which has the chemical formula CaCO3. Limestone exists in sedimentary and crystalline form.

Can I put dry ice in my freezer?
Q: Can I save dry ice in my freezer? A: No. Dry ice turns to a gas at –109.3° F, so even a freezer will be far too warm to prevent that from happening. And dry ice should never be kept in a walk-in freezer, because it produces carbon dioxide that can be hazardous in poorly ventilated areas.
