The combustion reaction of hexane:
2 C6H14 + 19 O2 = 12 CO2 + 14 H2O
2 mol C6H14 ---------> 12 mol CO2
x mol C6H14 ---------> 18.4 mol CO2
12 * x = 18.4 * 2
12 x = 36.8
x = 36.8 / 12
x = 3.067 moles of CO2
hope this helps!.

Answer:
132.94 kilo joules
Explanation:
We are given;
- Mass of benzene solution is 850 g
- Temperature change from 95°C to 3° C = 92° C or 92 K
We are required to determine the energy released by the cooling of benzene.
Taking the specific heat capacity of liquid benzene as 1.7 kJ/kg/K
Then we can determine the amount of heat energy released by using the formula;
Heat = Mass × specific heat × change in temperature
= 0.85 kg × 1.7 kJ/kg/K × 92 K
= 132.94 kilo joules
Therefore, the heat released by cooling benzene is 132.94 kilo joules
