Answer: The chemical formula of carbon dioxide is [tex]CO_2[/tex]
Explanation:
Chemical formula of any compound is the representation when elements combine with each other.
Carbon dioxide is a covalent compound and covalent compound is formed by the sharing of electrons between two elements that form a bond.
Electronic configuration of carbon: [tex]1s^22s^22p^2[/tex]
Carbon need 4 electrons to complete its octet.
Electronic configuration of oxygen: [tex]1s^22s^22p^4[/tex]
Oxygen need 2 electrons to complete its octet.
Hence, 2 oxygen atoms are required to complete the octet of 1 carbon atom. Hence, form a compound carbon dioxide [tex](CO_2)[/tex]
