Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)(1 point)ResponsesC=O–OC=O–OO=C=OO=C=OO=C–OO=C–OC–O–O
In carbon dioxide (CO2), carbon and oxygen are attached to each other through a double bond. Oxygen requires 2 electrons to complete its valence shell, and carbon has 4 valence electrons. By forming a double bond, carbon shares 2 of its valence electrons with one oxygen atom. The structure of carbon dioxide can be represented as:
O=C=O

The process most likely responsible for the formation of limestone caves is carbonation.
To determine the structure of carbon dioxide (CO2), we first look at the valence electrons of carbon and oxygen. Carbon (Group 14) has four valence electrons, while oxygen (Group 16) has six valence electrons.
In order to achieve a stable configuration, both carbon and oxygen need to complete their octets by sharing electrons. Each carbon atom will form two single bonds, while each oxygen atom will form a double bond.
The structure of carbon dioxide (CO2) is therefore as follows:
C=O
|
O
Here, the double bond is represented by "=", while the single bonds are represented by "-". The carbon atom is bonded to two oxygen atoms, one through a double bond and another through a single bond. This structure maintains the octet rule, with each atom having a total of eight electrons in its valence shell.
Therefore, the correct representation of the structure of carbon dioxide (CO2) is:
O=C=O
