Carbon dioxide (formula CO2) is a colorless, odorless gas. It is formed in the process of breathing. Chemical structure model: Ball and Stick. 3D illustration.
A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
