# C_6H_12O_6 + H_2O + en ergy -> CO_2 + O_2. How can you identify what is wrong with this equation?

Well, combustion of carbohydrates produces energy..........and also the equation is not stoichiometrically balanced.

#### Explanation:

The balanced chemical equation for complete combustion of glucose is:

${C}_{6} {H}_{12} {O}_{6} \left(s\right) + 6 {O}_{2} \left(g\right) \rightarrow 6 C {O}_{2} \left(g\right) + 6 {H}_{2} O \left(l\right) + \Delta$

The oxidizing agent is of course $\text{dioxygen}$, which the given equation also does not include.

Note, is this balanced? For every reactant particle is there a corresponding product particle?

The $\Delta$ symbol represents the heat produced in the reaction; i.e. it is an exothermic reaction, in which the strong $C = O$ and $O - H$ bonds FORMED outweigh the $C - C$, $C - H$, etc. bonds broken.
