Carbon monoxide is flammable, and carbon monoxide burns to generate carbon dioxide. The chemical equation of the reaction is: 2CO+O2=ignition=2CO2. At the same time, carbon monoxide is also reducing. Carbon monoxide reduces copper oxide to form copper and carbon dioxide. The chemical equation of the reaction is: CuO+CO=△=Cu+CO2.
Carbon monoxide, chemical formula CO, is a colorless, odorless, non-pungent gas. Under standard conditions, the relative molecular mass of carbon monoxide is 28.01, the density is 1.25g/l, the freezing point is -205.1°C, and the boiling point is -191.5°C. The solubility in water is very low, and it is extremely difficult to dissolve in water. The explosion limit of mixing with air is 12.5% to 74.2%.
Carbon monoxide is easily combined with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its ability and function to carry oxygen, causing tissue suffocation and death in severe cases. Carbon monoxide has a toxic effect on tissue cells throughout the body, especially the cerebral cortex. CO exists in metallurgy, chemistry, graphite electrode manufacturing, household gas or coal stoves, and automobile exhaust.
Chemical properties are: flammability, reduction, toxicity, very weak oxidation. The valence of carbon in the carbon monoxide molecule is +2, which can be further oxidized to +4, so that carbon monoxide is flammable and reducible, and carbon monoxide can be burned in air or oxygen to generate carbon dioxide.
