# Besides energy, what is produced when hydrocarbons are burned?

$\text{Greenhouse gases..........}$

#### Explanation:

${C}_{6} {H}_{14} \left(l\right) + \frac{19}{2} {O}_{2} \left(g\right) \rightarrow 6 C {O}_{2} \left(g\right) + 7 {H}_{2} O \left(l\right) + {\Delta}_{1}$

In cases of incomplete combustion, SOME $C O$ or $C$ may result. This is especially true in an internal combustion engine, or more so in a diesel engine............

${C}_{6} {H}_{14} \left(l\right) + 8 {O}_{2} \left(g\right) \rightarrow 4 C {O}_{2} \left(g\right) + C O + C + 7 {H}_{2} O \left(l\right) + {\Delta}_{2}$

So what do you think? Are these equations stoichiometrically balanced? Would ${\Delta}_{1} > {\Delta}_{2}$? Why or why not?

water and carbon dioxide

#### Explanation:

The general formula for combustion is

C_xH_y + O_2 => ?H_2O + ?CO_2

The coefficients for the water and carbon dioxide depend on the identity of the hydrocarbon.
