- The molecular ion S3N3 has the cyclic structure All SN bonds are equivalent. (a) Give six equivalent resonance hybrid Lewis diagrams for this molecular ion. (b) Compute the formal charges on all atoms in the molecular ion in each of the six Lewis diagrams. (c) Determine the charge on each atom in the polyatomic ion, assuming that the true distribution of electrons is the average of the six Lewis diagrams arrived at in parts (a) and (b). (d) An advanced calculation suggests that the actual charge resident on each N atom is 0.375 and on each S atom is +0.041 . Show that this result is consistent with the overall +1 charge on the molecular ion.The bond dissociation energy, in kJ, to break 1 bond in 1 mole of CO2 molecules is Single H Bond 432 411 386 459 HUN O C C=C C=C Multiple Bonds CN 346 305 167 358 602 201 O 142 C=O 799 CEO 1072 835 C=N 615 0=0 494 C=N 887 NEN 942 **All values in kJ/mol**tR-XZxj_1SoekWMaP1As1fEhnC179H4SICzl1mdWKpKlvbF3amiKazP.
