  1.    T,  T           Divide  and conquer.    Strong  acids   and strong  bases   are those   that

    undergo 100 percent dissociation in water.
    The strong acids are HCl, HBr, HI, HNO 3 , H 2 SO 4 , and
    HClO 4.
    The strong bases are LiOH, NaOH, KOH, RbOH, and
    CsOH.
    Mixing any acid with any base will produce a
    neutralization reaction, regardless of whether the acid
    and base are strong or weak.




Part C



  1. C Electrons don’t actually orbit the nucleus at fixed distances, although
    many textbooks use the graphical representation of the Bohr atom
    because it is difficult to draw the true electron orbitals (first proposed by
    Heisenberg) as a two-dimensional representation.

  2. D First, draw the Lewis dot structure for XeOF 4.
