Koltvíoxide

Koltvíoxide is the chemical compound with the formula CO2. It is a colorless gas with a faint but perceptible odor, composed of one carbon atom covalently bonded to two oxygen atoms. CO2 is a vital component of Earth's atmosphere and is involved in numerous natural processes. It is produced during the combustion of carbon-containing materials, respiration by living organisms, and volcanic activity.

Plants utilize carbon dioxide during photosynthesis to produce glucose, their primary source of energy, and release oxygen as a byproduct. This process forms the foundation of most food chains. In the atmosphere, CO2 acts as a greenhouse gas, trapping heat and contributing to the Earth's temperature regulation. However, increased concentrations of CO2 due to human activities, such as the burning of fossil fuels and deforestation, are a major driver of climate change and global warming.

CO2 has various industrial applications. It is used in the production of carbonated beverages, as a refrigerant in its solid form (dry ice), and in fire extinguishers. It also finds use in welding and in enhanced oil recovery. The chemical properties of CO2 make it a relatively stable compound under normal conditions.
