Question

To prepare and study the properties of carbon dioxide gas.​

Answer 1

Explanation:

If carbon dioxide is passed through limewater, it turns milky white. The decomposition of carbonate salts like calcium carbonate or magnesium carbonate produces carbon dioxide. When metallic carbonates or metallic bicarbonates react with sulphuric acid, they form carbon dioxide.

Answer 2

Answer:

Carbon Dioxide is a colorless, odorless, incombustible gas resulting from the oxidation of carbon. 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.
