a. Write the abbreviated ground state electron configuration for Rh4+ .

b. How many non-bonding electron dots are there in the Lewis structure for an ion of ClO2-

c. Calculate the formal charge of the carbon atom in the polyatomic ion of CO32-

d. How many valence electrons are around the central atom in ICl2-

e. Using bond energies from Table 8.1 what is the approximate H in kJ for the reaction

CH4(g) + 2O2(g) CO2(g) + 2H2O(g)

f. At a certain temperature, the bond dissociation energies for Cl2(g) and N2(g) are 202 kJ/mol and 902 kJ/mol, respectively.

Given the heat of formation for NCl3(g) as -54.0 kJ/mol, estimate the N-Cl bond energy in kJ/mol.( give 3 sig figures)
