Dry ice is the cold dense white mist produced by solid carbon dioxide in the air. The sublimation of dry ice is an endothermic reaction.

Dry ice is the solid form of carbon dioxide.
Dry ice IS the solid form of carbon dioxide. And "dry ice" IS the common name for the solid CO2. So the question should be "What substance is the common name Dry Ice used for ? "
It is called "dry" because when heat is given, it sublimes (turns from a solid into a gas). This is different from actual ice that turns from a solid to a liquid. It is called "ice" because solid carbon dioxide (dry ice) is very cold, similar to ice.
Dry ice bombs are usually created from a container like plastic bottles, water, and dry ice. The solid carbon dioxide becomes warmer resulting to increase in pressure and limited room to expand.
Yes, the process of dry ice sublimation is exothermic. When dry ice (solid carbon dioxide) changes directly into gas without passing through the liquid phase, it releases heat energy, making it an exothermic process.
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
yes.
The dry ice will sublimate, which means it will change from a solid directly to a gas without passing through the liquid state. This process occurs due to the low temperature of dry ice (-78.5°C) compared to room temperature, causing it to transition directly to carbon dioxide gas.
The dissolvation of salt in water is exothermic.

Definitions Exothermic - accompanied by, or requiring, the release of heat. Endothermic - accompanied by, or requiring, the absorption of heat. Now, does the melting ice get warmer or colder? If it gets colder, then it is exothermic. If it gets warmer, then it is endothermic. Consider how we make ice - we put water into a cold place so that it gets colder with time.
Dry ice is frozen carbon dioxide.
Yes, dry ice is opaque.
