Carbon Dioxide(A Carbon-Oxygen Compound)
Carbon dioxide is a carbon-oxygen compound with the chemical formula CO2 and a chemical formula quantity of 44.0095. It is a colorless and odorless or colorless and odorless gas at normal temperature and pressure, and its aqueous solution has a slightly sour smell. It is also a common Greenhouse gases are also one of the components of air (accounting for 0.03%-0.04% of the total volume of the atmosphere).
In terms of physical properties, carbon dioxide has a melting point of -56.6°C (527kPa), a boiling point of -78.5°C, is denser than air (under standard conditions), and is soluble in water.
In terms of chemical properties, carbon dioxide is chemically inactive and has high thermal stability (only 1.8% decomposes at 2000°C). It cannot burn and usually does not support combustion. It is an acidic oxide and has the properties of an acidic oxide. Since it reacts with water to form carbonic acid, it is an anhydride of carbonic acid.
