Title: Standard enthalpies of formation question Post by: vanbu on Jul 23, 2013 I have a question in my Chemistry textbook I can't seem to solve. ???
I know that heat of formation= delta H= sum of bonds broken minus sum of bonds formed. Can you help? The standard enthalpies of formation for S (g), F (g), SF4 (g), and SF6 (g) are +278.8, +79.0, -775, and -1209 kJ per mole, respectively. What is the energy of the S--F bond WITHOUT using the dissociation energy bond chart. (Step by step proof is needed) Thank you!
