To determine the elemental composition of each compound, we will break down their molecular formulas:

  1. C₆H₁₂O₆ (Glucose)

    • 6 carbon atoms (C)
    • 12 hydrogen atoms (H)
    • 6 oxygen atoms (O)
  2. C₁₂H₂₂O₁₁ (Sucrose)

    • 12 carbon atoms (C)
    • 22 hydrogen atoms (H)
    • 11 oxygen atoms (O)
  3. C₅H₁₀O₅ (Ribose)

    • 5 carbon atoms (C)
    • 10 hydrogen atoms (H)
    • 5 oxygen atoms (O)

Now we can fill in the table with the elemental compositions for each compound.

| Compound | Carbon Atoms | Hydrogen Atoms | Oxygen Atoms | |-------------|---------------|----------------|--------------| | C₆H₁₂O₆ | 6 | 12 | 6 | | C₁₂H₂₂O₁₁ | 12 | 22 | 11 | | C₅H₁₀O₅ | 5 | 10 | 5 |

Summary of Elemental Composition

  • C₆H₁₂O₆: 6 C, 12 H, 6 O
  • C₁₂H₂₂O₁₁: 12 C, 22 H, 11 O
  • C₅H₁₀O₅: 5 C, 10 H, 5 O

This comparison gives us a clear understanding of the composition of the three compounds. Let me know if you need further assistance!
