What is the chemical symbol for carbon dioxide?

The chemical symbol for carbon dioxide is CO2. This notation indicates that each molecule of carbon dioxide is made up of one carbon atom (C) bonded to two oxygen atoms (O). The subscript '2' following the 'O' signifies the presence of two oxygen atoms in the molecule, which is essential for understanding the composition of carbon dioxide.

This particular formula is widely recognized in various fields, including chemistry and environmental science, as it describes a key greenhouse gas resulting from combustion processes and is significant in discussions about climate change and atmospheric science. The correct identification of chemical symbols is crucial for students and professionals to communicate effectively about chemical substances and their properties accurately.
