süsinikdioksüdid
süsinikdioksüdid (CO₂) is a colorless, odorless inorganic compound consisting of one carbon atom double‑bonded to two oxygen atoms. It is a simple yet essential molecule in the Earth's atmosphere and a major greenhouse gas. Chemically, CO₂ is a weak acid; in aqueous solution it forms carbonic acid (H₂CO₃), which plays a crucial role in regulating pH in biological systems and in the oceans. The molecule is linear, with a bond angle of 180°, and it has no permanent dipole moment, though it exhibits quadrupole interactions.
Physical properties include a melting point of −78.5 °C and a boiling point of 31.0 °C under standard atmospheric
Natural sources of CO₂ include respiration of organisms, volcanic activity, and the decomposition of organic matter.
Applications of CO₂ span multiple industries. It is used in carbonation of beverages, fire suppression systems,
