# What is the balanced equation for the incomplete combustion of heptene, C_7H_14?

Mar 31, 2017

${C}_{7} {H}_{14} \left(l\right) + 9 {O}_{2} \left(g\right) \rightarrow 5 C {O}_{2} \left(g\right) + C O \left(g\right) + C \left(s\right) + 7 {H}_{2} O \left(l\right)$

#### Explanation:

Is the given equation stoichiometrically balanced?

And how did I know that 1 mole each of carbon monoxide and carbon (as soot) would result? Of course, I don't KNOW that, but I can nevertheless represent the possibility: i.e. some of the carbon is incompletely combusted. I could also represent the thermodynamic properties of the equation.

Of course complete combustion demands complete carbon oxidation to give:

${C}_{7} {H}_{14} \left(l\right) + \frac{21}{2} {O}_{2} \left(g\right) \rightarrow 7 C {O}_{2} \left(g\right) + 7 {H}_{2} O \left(l\right)$
