# What is the standard enthalpy of the combustion of ethene?

${H}_{2} C = C {H}_{2} \left(g\right) + 3 {O}_{2} \left(g\right) \rightarrow 2 C {O}_{2} \left(g\right) + 2 {H}_{2} O \left(l\right) + \Delta$
$\Delta {H}_{\text{combustion}}^{\circ}$ for ethylene will be reported somewhere in your text.
