(3 points) Responses: cardon bond oxygen hydrogen
I apologize, but the given question and answer options do not correlate with each other. The chemical formula for propane is C3H8, which indicates that the compound consists of three carbon atoms (C3) and eight hydrogen atoms (H8). There is no mention of an oxygen atom or a carbon bond in the formula.
Therefore, I am unable to label the diagram based on the given options. If you have a different question or require further assistance, please let me know.
The white spheres represent

atoms.
The white spheres represent hydrogen atoms. The red spheres represent oxygen atoms. The grey spheres represent carbon atoms.
Keep thinking about the models shown above, and consider which elements are represented by which colors.

To label the diagram of propane, we need to understand the meaning of the letters and numbers in its chemical formula, C3H8.
The letter "C" represents carbon, which is a chemical element. In propane, there are three carbon atoms, indicated by the number "3".
The letter "H" represents hydrogen, another chemical element. In propane, there are eight hydrogen atoms, indicated by the number "8".
Therefore, to label the diagram:
- The element represented by the letter "C" should be labeled as "Carbon".
- The element represented by the letter "H" should be labeled as "Hydrogen".
- The number "3" next to the letter "C" should be labeled as "Carbon Atoms".
- The number "8" next to the letter "H" should be labeled as "Hydrogen Atoms".
Please note that in the original question, the word "oxygen" is mentioned. However, propane does not contain any oxygen atoms and is solely composed of carbon and hydrogen atoms.
