To label the diagram for ethane (C₂H₆), you'll need to understand the components represented in the chemical formula and how they relate to the structure of the molecule. Here's how you can label them:

  1. C: Carbon atom
  2. H: Hydrogen atom
  3. Subscripts: The numbers indicating how many of each type of atom are present in the molecule (2 for carbon and 6 for hydrogen).

If you have a diagram of ethane, you would place your labels in the following ways:

  • Drop target 1: Label the carbon atoms (C) shown in the diagram.
  • Drop target 2: Label the hydrogen atoms (H) shown in the diagram.
  • Drop target 3: Label the subscripts (2 and 6) that indicate how many carbon and hydrogen atoms are present, respectively.

Make sure to drag and drop the labels to the correct parts of the diagram to illustrate the molecular structure of ethane clearly.
