# What is the balanced equation for the combustion of ethanol?

Dec 17, 2015

${H}_{3} C - C {H}_{2} O H \left(l\right) + \frac{7}{2} {O}_{2} \left(g\right) \rightarrow 2 C {O}_{2} \left(g\right) + 3 {H}_{2} O \left(l\right)$

#### Explanation:

Is the equation above balanced? How do you know? Can I have half a molecule of oxygen? Note that the equation is not only balanced stoichiometrically, it is balanced energetically, in that the combustion of a given quantity of ethanol will give rise to a given quantity of energy.
