Question

Carbon dioxide can be represented by the chemical formula

Answer 1

Answer: The chemical formula of carbon dioxide is $CO_2$

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: $1s^22s^22p^2$

Carbon need 4 electrons to complete its octet.

Electronic configuration of oxygen: $1s^22s^22p^4$

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 $(CO_2)$

Answer 2

Carbon dioxide is represented as 'CO2' by the chemical formula.
