Question
Chapter 13, Problem 115AE
Interpretation Introduction
Interpretation: The instability of the given halides of nitrogen needs to be explained.
Concept Introduction: The stability of any molecule depends on the formation of the bond between the atoms of the molecule. If the size of the atoms is comparable, an effective overlapping will take place and formation of stable molecules takes place.

The element xenon (Xe) is by no means chemically inert;it forms a number of chemical compounds with electronegative elements such as fluorine and oxygen. The reaction of xenon with varying amounts of fluorine producesXeF2 and XeF4. Subsequent reaction of one or the otherof these compounds with water produces (depending onconditions) XeO3, XeO4, and H4XeO6, as well as mixedcompounds such as XeOF4. Predict the structures ofthese six xenon compounds, using the VSEPR theory.
Ammonia is an important chemical used in the
production of fertilizer. Industrial production of
ammonia from atmospheric nitrogen is difficult
because of the energy required to cleave the
N-N triple bond. Consider the balanced reaction
of ammonia: N2(g) + 3H2(g) → 2 NH3 (9).
This reaction has a value of K = 4.3 x 10-2 at 25
°C.
