Following are some important properties of ionic compounds:
Answer to relevant QuestionsUse the following data to estimate ΔHof for potassium chloride. K(s) + 1/2 Cl2(g) → KCl(s) 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 Consider the following reaction: A2 + B2 → 2AB ΔH = –285 kJ The bond energy for A2 is one- half the amount of the AB bond energy. The bond energy of B2 = 432 kJ/ mol. What is the bond energy of A2? 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. ...Borazine (B3N3H6) has often been called “inorganic” benzene. Draw Lewis structures for borazine. Borazine is a six-membered ring of alternating boron and nitrogen atoms.
