What is the chemical name of Dry Ice?

Carbon dioxide

The correct answer is option 4. Carbon dioxide.

The chemical name of Dry Ice is Carbon dioxide.

Dry Ice is solid carbon dioxide (CO2) at a temperature of -78.5°C (-109.3°F). It is commonly used as a cooling agent and is called "dry ice" because it sublimes directly from a solid to a gas without passing through a liquid phase. Therefore, the correct chemical name is carbon oxide, which is a common term for carbon dioxide when it is in its solid form.
