Identifying the Reducing Agent in a Redox Equation

CHEM-PYBAYW

The process of aerobic respiration that takes place in organisms to generate energy can be represented by the following simplified equation:

$${ C }_{ 6 }{ H }_{ 12 }{ O }_{ 6 }(s)+6{ O }_{ 2 }(g)\xrightarrow [ ]{ } 6{ CO }_{ 2 }(g)+6{ H }_{ 2 }O(l)+\text{heat}$$

Which of the species below is functioning as the reducing agent?

A

${ C }_{ 6 }{ H }_{ 12 }{ O }_{ 6 }(s)$

B

${ O }_{ 2 }(g)$

C

${ CO }_{ 2 }(g)$

D

${ H }_{ 2 }O(l)$
