Carbon dioxide normally occurs as a colorless gas. In solid form it is called dry ice. The chemical or molecular formula for carbon dioxide is CO 2. The central carbon atom is joined to two oxygen atoms by covalent double bonds. The chemical structure is centrosymmetric and linear, so carbon dioxide has no electric dipole.

It also contains a small density that cannot be assigned to the polypeptide chain (Fig. 1b), indicating the presence of a molecular inclusion of low polarity. In this study, we have analyzed the.

René Descartes was born in La Haye en Touraine (now Descartes, Indre-et-Loire), France, on 31 March 1596. His mother, Jeanne Brochard, died soon after giving birth to him, and so he was not expected to survive. Descartes’ father, Joachim, was a member of the Parlement of Brittany at Rennes. René lived with his grandmother and with his great-uncle.
