Which of the listed statements describes the results of the following reaction? c 6 h 12 o 6 + 6 o 2 → 6 co 2 + 6 h 2 o + energy a) c 6 h 12 o 6 is oxidized and o 2 is reduced. b) o 2 is oxidized and h 2 o is reduced. c) co 2 is reduced and o 2 is oxidized. d) o 2 is reduced and co 2 is oxidized.

Explanation:

1) Chemical equation:

2) Oxidation states in the reactants

a) C₆H₁₂O₆

Here, you will see that the oxidation state of carbon in glucose is zero.

There are 6 atoms of C which may have different oxidation number.

You can work with a more developed formula such as:

     O    OH   OH    OH   OH  OH

     ║     |        |         |       |       |

H - C¹ -  C²  -  C³  -  C⁴ - C⁵  - C⁶ - H

             |        |         |       |       |

             H     H       H      H     H

        ∴ C¹ 's oxidation state may be determined from x + (−2) + (0) + (+1) = 0

            ⇒ x = + 1

       ∴ Their oxidation states are given by:

            x + (−1) + 2(0) + (+1) = 0 ⇒ x=0

        ∴ C⁶ 's oxidation state may be determined from:

             x + (−1) + (0) + 2(+1) = +1 ⇒ x = −1

b) O₂ : since it is alone, its oxidation state is zero.

3) Oxidation states in the products

c)  CO₂

d) H₂O

4) Changes in the oxidation state

5) Conclusion:

i think it's c. i'm not sure but i think so.
