# The following reaction is an example what type of reaction? 2C_2H_6(g) + 7O_2(g) + 4CO_2(g) + 6H_2O(g)

${C}_{2} {H}_{6} + \frac{7}{2} {O}_{2} \left(g\right) \rightarrow 2 C {O}_{2} + 3 {H}_{2} O \left(l\right) + \Delta$
The carbon of ethane $\left(C , - I I I\right)$, undergoes formal 7 electron oxidation to give fully oxidized $C {O}_{2}$. What is reduced in the reaction?
