1 answer

To determine which pairs of compounds have different ratios of carbon atoms to oxygen atoms, we need to examine the formulas provided:

  1. CO2 (1 carbon, 2 oxygen) - Ratio: 1:2 C2H4O4 (2 carbon, 4 oxygen) - Ratio: 2:4 or 1:2

    Conclusion: Same ratio (1:2)

  2. Li2CO3 (2 lithium, 1 carbon, 3 oxygen) - Ratio: 1:3 CaCO3 (1 calcium, 1 carbon, 3 oxygen) - Ratio: 1:3

    Conclusion: Same ratio (1:3)

  3. CH4OH (1 carbon, 1 oxygen) - Ratio: 1:1 C2H4O2 (2 carbon, 2 oxygen) - Ratio: 1:1

    Conclusion: Same ratio (1:1)

  4. C2H12O6 (2 carbon, 6 oxygen) - Ratio: 1:3 C4H8O (4 carbon, 1 oxygen) - Ratio: 4:1

    Conclusion: Different ratios (1:3 for the first, 4:1 for the second)

Overall, the pair that has different ratios of carbon to oxygen is C2H12O6 and C4H8O.
