Question: The lattice energies of FeCl3 FeCl2 and Fe2O3 are in
The lattice energies of FeCl3, FeCl2, and Fe2O3 are (in no particular order) –2631 kJ/ mol, –5339 kJ/ mol, and –14,774 kJ/ mol. Match the appropriate formula to each lattice energy.
Answer to relevant QuestionsUse bond energy values in Table to estimate ΔH for each of the following reactions in the gas phase. a. H2(g) + Cl2(g) → 2HCl(g) Table 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. The ...Write Lewis structures that obey the octet rule for each of the following. Except for HCN and H2CO, the first atom listed is the central atom. For HCN and H2CO, carbon is the central atom. a. HCN b. PH3 c. CHCl3 d. NH4+ e. ...An important observation supporting the need for resonance in the LE model is that there are only three different structures of dichlorobenzene (C6H4Cl2). How does this fact support the need for the concept of resonance? Place the species below in order of the shortest to the longest nitrogen– oxygen bond. H2NOH, N2O, NO+, NO2-, NO3- (H2NOH exists as H2NOOH.)
