Correct the following statement: “The bonds in solid PbCl2 are ionic; the bond in a HCl molecule is covalent. Thus, all of the valence electrons in PbCl2 are located on the Cl– ions, and all of the valence electrons in a HCl molecule are shared between the H and Cl atoms.”

Based on Lewis structures, predict the ordering, from shortestto longest, of N¬O bond lengths in NO+, NO2-, andNO3-.
