There are many different hydrocarbons that are used as fossil fuels. For each of the following fuels, determine the mass (ing) of CO2 that would be produced by burning enough fuel to produce 250. kJ of heat. Place your answer to three significant figures) in the boxes below. In this question, assume a complete combustion reaction, and assume the standard enthapy of formation for CO2 is -393.5 kJ/mol and H2O is -241.8 kJ/mol. Pentane, C5H12 (AHF = -146.8 kJ/mol) Butane, C4H10 (AHF = -125.8 kJ/mol) Octane, C8H18 (AH = -249.7 kJ/mol) Based on your answers, which fuel contributes least to the increase in atmospheric CO2 per k) of heat produced?

There are many different hydrocarbons that are used as fossil fuels. For each of the following fuels, determine the mass (ing)
of CO2 that would be produced by burning enough fuel to produce 250. kJ of heat. Place your answer to three significant
figures) in the boxes below.
In this question, assume a complete combustion reaction, and assume the standard enthapy of formation for CO2 is -393.5
kJ/mol and H2O is -241.8 kJ/mol.
Pentane, C5H12 (AHF = -146.8 kJ/mol)
Butane, C4H10 (AHF = -125.8 kJ/mol)
Octane, C8H18 (AH = -249.7 kJ/mol)
Based on your answers, which fuel contributes least to the increase in atmospheric CO2 per k) of heat produced?
