Xe Predict the empirical formulas of the ionic compounds formed from the following pairs of elements. Name each compound. a. Al and S b. K and N c. Mg and Cl d. Cs and Br Use the following data (in kJ/ mol) to estimate ΔH for the reaction S-(g) + e- → S2-(g). Include an estimate of uncertainty. S(s) → S(g) ΔH = 277 kJ/ mol S(g) + e- → S-(g) ΔH = –200. kJ/ mol The space shuttle orbiter uses the oxidation of methyl hydrazine by dinitrogen tetroxide for propulsion: 5N2O4(g) + 4N2H3CH3(g) → 12H2O(g) + 9N2(g) + 4CO2(g) Use bond energies to estimate DH for this reaction.
