Final answer:
In the context of carbon dioxide molecules, the correct equation representing the relationship between the number of carbon atoms and oxygen atoms is O = 2 * C, which signifies that the number of oxygen atoms is twice the number of carbon atoms.A) O = 2 * C
Step-by-step explanation:
The question is about determining the relationship between the number of oxygen atoms and the number of carbon atoms in molecules of carbon dioxide (CO2). Since each molecule contains 1 carbon atom and 2 oxygen atoms, the number of oxygen atoms is always twice the number of carbon atoms.
Therefore, the correct equation for finding the number of oxygen atoms when given the number of carbon atoms is: O = 2 * C. This indicates that if you know the amount of carbon atoms (C), you can find the amount of oxygen atoms (O) by simply doubling the number of carbon atoms.
