The fat C57H104O6 (s) is metabolized via the following reaction. calculate the energy (KJ) liberated when 1g of this fat reacts. C57H104O6(s)+80O2(g)→57CO2(g)+52H2O(l) Given the enthalpies of formation: ΔH0f(C57H104O6,s)=−70870 kJ/mol ΔH0f(H2O,l)=−285.8 kJ/mol ΔH0f(CO2,g)=−393.5 kJ/mol

Answer»

The fat C57H104O6 (s) is metabolized via the following reaction.
calculate the energy (KJ) liberated when 1g of this fat reacts.

C57H104O6(s)+80O2(g)57CO2(g)+52H2O(l)

Given the enthalpies of formation:

ΔH0f(C57H104O6,s)=70870 kJ/mol
ΔH0f(H2O,l)=285.8 kJ/mol
ΔH0f(CO2,g)=393.5 kJ/mol
