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. Draw Lewis structures for silicon tetrachloride and the nitrate ion . ... How many equivalent Lewis structures are necessary to describe the bonding in SiCl4 ? How many equivalent Lewis structures are necessary to describe the bonding in NO3- ?
