Answer:

#2C_3H_7COC_2H_5+17O_2->12CO_2+12H_2O#

Explanation:

Complete combustion of #C_3H_7COC_2H_5# in oxygen will produce Carbon dioxide and water. If #a,b,c,d# are the respective molecules in the balanced equation, we have

#aC_3H_7COC_2H_5+bO_2->cCO_2+dH_2O#

Lets start with #a=1#. Balancing the number of carbon on both sides we obtain #c=6#. And the equation becomes
#aC_3H_7COC_2H_5+bO_2->6CO_2+6H_2O#

#C_3H_7COC_2H_5+bO_2->6CO_2+dH_2O#
Now balancing hydrogen atoms we obtain #d=6#. And the equation becomes

#C_3H_7COC_2H_5+bO_2->6CO_2+6H_2O#
Now balancing #O# atoms we see that it #b=17/2#
Multiplying all with 2 we obtain balanced equation as

#2C_3H_7COC_2H_5+17O_2->12CO_2+12H_2O#
