question 41

Multiple Choice

The carbon cycle characterizes the cyclic transformations of the element carbon through the environment and biomass. Some of the important species in this cycle are CO₂, CO₃^2-, C₆H₁₂O₆, and CH₄. Which of these compounds would undergo complete oxidation by O₂ to give the largest change in oxidation number?

• A) CO₂
• B) CO₃^2-
• C) C₆H₁₂O₆
• D) CH₄
• E) CO₂ and CO₃^2- are equivalent in this regard.
