Carbon dioxide (CO₂) is a colorless, odorless gas at room temperature and pressure, known for its role in the Earth's atmosphere and biological processes. It is a linear molecule, consisting of one carbon atom covalently bonded to two oxygen atoms, with a molecular weight of approximately 44.01 g/mol. CO₂ is produced naturally through processes such as respiration, combustion, and decomposition, and it is also a byproduct of various industrial activities. It is soluble in water, forming carbonic acid, which plays a crucial role in the carbon cycle and ocean chemistry. Carbon dioxide is a greenhouse gas, contributing to global warming by trapping heat in the atmosphere. Its concentration is monitored due to its environmental impact, particularly in relation to climate change. In terms of safety, CO₂ is generally non-toxic at low concentrations, but high levels can lead to asphyxiation by displacing oxygen in the air. Its CAS number, 124-38-9, is used for identification in chemical databases and regulatory frameworks.
