To label the diagram of ethane (C2H6), you typically have the following components to label:

  1. C - This represents carbon atoms. In the formula C2, there are 2 carbon atoms.
  2. H - This represents hydrogen atoms. In the formula H6, there are 6 hydrogen atoms.
  3. Subscripts - The numbers (2 and 6) indicate the number of each type of atom in the molecule. The subscript '2' after C means there are 2 carbon atoms, and the subscript '6' after H means there are 6 hydrogen atoms.
  4. Molecular Structure - You might need to label how the carbon atoms bond with each other and how the hydrogen atoms are bonded to the carbon atoms.

To summarize for the labeling:

  • Carbon atoms: Label the two 'C' in the diagram.
  • Hydrogen atoms: Label the six 'H' in the diagram.

If there are structural lines connecting atoms, you may also want to indicate:

  • Bonds: The lines connecting the carbon to hydrogen and between the carbon atoms themselves represent chemical bonds.

If you are working with a specific diagram, please ensure the labels correspond to the visual elements of the diagram.
