combustion analysis
Your second equation is not balanced and you are not indicating any CO or O2 in the products of combustion.
Hint:
Write the second equation as
aC5H32 + bO2 + cN2 = 10.111CO2 + 1.000CO + 5.611O2 + 83.278N2 + dH2O
and determine correct values for a,b,c,d so that equation balances. Then proceed from there.
