Te2-, I-, Cs+, Ba2+, La3+ Which of the following ions have noble gas electron configurations? a. Fe2+, Fe3+, Sc3+, Co3+ c. Pu4+, Ce4+, Ti4+ b. Tl+, Te2-, Cr3+ d. Ba2+, Pt2+, Mn2+ Consider the following: Li(s) + 1/2 I2(g) → LiI(s) ΔH = –292 kJ. LiI(s) has a lattice energy of –753 kJ/ mol. The ionization energy of Li(g) is 520. kJ/ mol, the bond energy of I2(g) is 151 kJ/ mol, and the electron ...Use data from Table to estimate ΔH for the combustion of methane (CH4), as shown below: Table Use the following standard enthalpies of formation to estimate the NOH bond energy in ammonia. Compare this with the value in Table. N(g) 472.7 kJ/ mol H(g) 216.0 kJ/ mol NH3(g) –46.1 kJ/ mol
