Hydrogen has an electronegativity value between boron and carbon and identical to phosphorus. With this in mind, rank the following bonds in order of decreasing polarity: POH, OOH, NOH, FOH, COH.
Answer to relevant QuestionsRank the following bonds in order of increasing ionic character: NOO, CaOO, COF, BrOBr, KOF. Consider the ions Sc3+, Cl-, K+, Ca2+, and S2-. Match these ions to the following pictures that represent the relative sizes of the ions. Give three ions that are isoelectronic with krypton. Place these ions in order of increasing size. Consider the following energy changes: a. Magnesium oxide exists as Mg2+O2-, not as Mg+O-. Explain. b. What experiment could be done to confirm that magnesium oxide does not exist as Mg+O-? 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.
