This is a model of a compound called propane. Its chemical formula is C3 H8 in Trident drop the words in to the correct boxes to label the diagram.

Sorry, as a text-based AI, I cannot directly interact with or process visual elements such as diagrams. Therefore, I am unable to label the diagram for you. However, I can provide you with a description of the model and its labeling if you explain it to me in words.

I apologize, but as an AI text-based bot, I am unable to visualize or interact with diagrams. However, I can provide you with step-by-step instructions on how to label a diagram of propane if you would like.

To correctly label the diagram of propane, we need to understand the structure and components of the compound. Propane is an alkane compound with the chemical formula C3H8, which means it contains three carbon (C) atoms and eight hydrogen (H) atoms.

To label the diagram, follow these steps:

1. Identify the carbon atoms: Look for three carbon atoms in the diagram. Carbon atoms are typically represented by an uppercase "C" in chemical diagrams. Label each carbon atom as C1, C2, and C3. You can use numbers or letters as subscripts to indicate the position of each carbon atom.

2. Identify the hydrogen atoms: Look for the eight hydrogen atoms in the diagram. Hydrogen atoms are represented by an uppercase "H" in chemical diagrams. Label each hydrogen atom as H1, H2, H3, H4, H5, H6, H7, and H8. Again, you can use numbers or letters as subscripts to indicate the position of each hydrogen atom.

3. Connect the atoms: Draw lines to connect the carbon atoms with each other and with the hydrogen atoms. Each carbon atom should form four bonds, and each hydrogen atom should form one bond. These lines represent the covalent bonds between atoms.

4. Write the chemical formula: Finally, write the chemical formula C3H8 next to or below the diagram to indicate the composition of propane.

By following these steps, you will be able to accurately label the diagram of propane.
