General Chemistry

Question #181610

Calculate Hf for this reaction: 6C(s)+6H2(g)+3O2(g)C6H12O6(s)

using the following three equations:

C(s)+O2(g)CO2 (g) H= -393.51 kJ

H2(g)+(1/2)O2(g)H2O(l) H= -285.83 kJ C6H12O6(s)+6O2 (g)6CO2 (g)+6H2O(l) H= -2803.02 kJ

Expert's answer

Hf= -393.51-285.83-2803.02=-3482.36
