Based on formal charge considerations, which of the following would likely be the correct arrangement of atoms in nitrosyl chloride: ClNO or ClON?

Using the bond energies in Table 7.2, determine the approximate enthalpy change for the following reaction:            CH4(g) + I2(g) –> CH3I(g) +HI(g)

Using the bond energies in Table 7.2, determine the approximate enthalpy change for the following reaction:                   H2C=CH2(g) + H2(g) –> H3CCH3(g)

Explain how σ and π bonds are similar and how they are different. To receive full credit you need to address electron density location. You may find a sketch would be helpful.

Use principles of atomic structure to answer each of the following: (a) The radius of the Ca atom is 197 pm; the radius of the Ca2+  ion is 99 pm. Account for the difference. (b) The lattice energy of CaO(s) is –3460 kJ/mol; the lattice energy of K2O is –2240 kJ/mol. Account for the difference. (c) Given these ionization values, explain the difference between Ca and K with regard to their first and second ionization energies. Element First Ionization Energy (kJ/mol) Second Ionization Energy (kJ/mol) K 419 3050 Ca 590 1140 (d) The first ionization energy of Mg is 738 kJ/mol and that of Al is 578 kJ/mol. Account for this difference. This is a four part question. To receive full credit you must address each part.

Using the bond energies in Table 7.2, determine the approximate enthalpy change for the following reaction:              2C2H6(g) + 7O2(g) –> 4CO2(g) + 6H2O(g)
