Get started for freeIs it possible to "trap" a resonance structure of a compound for study? Explain.
True or false: (a) Formal charges represent actual separation of charges; (b) \(\Delta H_{\mathrm{rxn}}^{\circ}\) can be estimated from bond enthalpies of reactants and products; (c) all second-period elements obey the octet rule in their compounds; (d) the resonance structures of a molecule can be separated from one another.
What is lattice energy and what role does it play in the stability of ionic compounds?
Write Lewis dot symbols for the following atoms and ions: (a) I, (b) I \(^{-},\) (c) S, (d) \(\mathrm{S}^{2-},\) (e) \(\mathrm{P},\) (f) \(\mathrm{P}^{3-}\), (l) \(\mathrm{Al}^{3+}\) (g) \(\mathrm{Na},\) (h) \(\mathrm{Na}^{+},\) (i) \(\mathrm{Mg},\) (j) \(\mathrm{Mg}^{2+},\) (k) \(\mathrm{Al}\), \((\mathrm{m}) \mathrm{Pb},(\mathrm{n}) \mathrm{Pb}^{2+}\).
Define bond enthalpy. Bond enthalpies of polyatomic molecules are average values. Why?
