The enthalpy change for the following reaction is -318 kJ. OF2(g) + H2O(g) --> O2(g) + 2HF(g) a) To analyze the reaction, first draw Lewis structures for all reactant and product molecules. b) Estimate the O-F bond energy in OF2(g) , using tabulated bond energies (linked above) for the remaining bonds. Bond data for question two can be found in a references chart by googling bond energy (will not allow photo upload) H - O = 463kJ O=O = 498kJ...

The enthalpy change for the following reaction is -542 kJ. Using bond energies, estimate the F-F bond energy in F2(g). H2(g) + F2(g)2HF(g) kJ/mol Resonance Structures are ways to represent the bonding in a molecule or ion when a single Lewis structure fails to describe accurately the actual electronic structure. Equivalent resonance structures occur when there are identical patterns of bonding within the molecule or ion. The actual structure is a composite, or resonance hybrid, of the equivalent contributing structures....
