Definition
Carbon dioxide is a one-carbon compound with formula CO2 in which the carbon is attached to each oxygen atom by a double bond. A colourless, odourless gas under normal conditions, it is produced during respiration by all animals, fungi and microorganisms that depend directly or indirectly on living or decaying plants for food. It has a role as a vasodilator agent, an anaesthetic, a solvent, an antagonist, a mouse metabolite, a Saccharomyces cerevisiae metabolite, a member of greenhouse gas, an Escherichia coli metabolite, a human metabolite, a member of food packaging gas, a food propellant and a refrigerant. It is a gas molecular entity, a carbon oxide and a one-carbon compound.

Measured properties
- Appearance
- Carbon dioxide appears as a colorless odorless gas at atmospheric temperatures and pressures. Relatively nontoxic and noncombustible. Heavier than air and may asphyxiate by the displacement of air. Soluble in water. Forms carbonic acid, a mild acid. Under prolonged exposure to heat or fire the container may rupture violently and rocket. Used to freeze food, to control chemical reactions, and as a · Carbon dioxide, refrigerated liquid appears as a colorless liquid. Relatively heavier than air and can asphyxiate by the displacement of air. Under prolonged exposure to heat or fire the container may rupture violently and rocket. Used as a refrigerant and in making carbonated beverages. Used to freeze food, to control chemical reactions and as a fire extinguishing agent.
