Answer

$C_2H_5OH$ - 0 molecules $O_2$ - 1 molecule $CO_2$ - 4 molecules $H_2O$ - 6 molecules

Work Step by Step

$C_2H_5OH+3O_2\rightarrow 2CO_2+3H_2O$ is the balanced equation. 2 ethanol and 6 oxygen molecules will combine, leaving 1 oxygen and no ethanol molecules unconsumed and creating 4 carbon dioxide and 6 water molecules. $2C_2H_5OH+6O_2\rightarrow 4CO_2+6H_2O$
