Question

The lattice enegry for magnesium 0xide is 3890 KJ/mol. What is the chemical equation that describe this? Draw all of the resonance structure for the nitrous oxide(N2O). Using formal charges, which structure is more reasonable? What is the enthalpy of combustion of 1 mol of hydrogen gas (forming water vapor) using the bond enthalpies from your book? With the Lewis dot structures of carbon dioxide and carbon monoxide, explain the oxidation numbers of carbon and oxygen using electronegativity. What are the thermochemical equations for the bond enthalpies of nitrogen, oxygen, and chlorine? What is the correlation between bond length, number of electrons in a bond, and bond strength?

Explanation / Answer

1)Lattice energy is defined as the energy required to completely separate one
mole of a solid ionic compound into its gaseous ions. Therefore, this will be a
positive value (and endothermic process). For magnesium oxide, the equation is:
MgO(s) ? Mg2+(g) + O2
