Answer
$C_7H_8O_2(l)+8O_2\rightarrow 7CO_2(g)+4H_2O$
This is combustion.
Work Step by Step
$C_7H_8O_2(l)+O_2\rightarrow CO_2(g)+H_2O$
A hydrocarbon reaction with oxygen is a combustion reaction.
Add a coefficient of 7 to $CO_2$ to balance $C$.
Add a coefficient of 4 to $H_2O$ to balance $H$.
$C_7H_8O_2(l)+O_2\rightarrow 7CO_2(g)+4H_2O$
Add a coefficient of 8 to $O_2$ to balance $O$.
$C_7H_8O_2(l)+8O_2\rightarrow 7CO_2(g)+4H_2O$
