Homework Answers
1) 2FeCl3 (aq) + Fe(s) → 3FeCl2 (aq)
Ionic equation : 2Fe+3 (Aq) + Fe(s) + 6Cl- (aq) ------> 3Fe+2(aq) + 6Cl-(aq)
Net ionic equation : 2Fe+3 (Aq) + Fe(s) ------> 3Fe+2(aq)
2) Cl2O : Dichlorine monoxide : Total number of valence electrons : 20 valence electrons
b) NH2- : Amine ion : Total number of valence electrons : 8 valence electrons
c) AsH3 : Arsenic trihydride : Total number of valence electrons : 8 valence electrons
Lewis structures and shape of above molecules are in the below image :

To understand solubility we must look at two important characteristics: geometry and bond polarity ionic, nonpolar and polar). From these two characteristics the overall molecular polarity can be determined. The statement "like dissolves like" provides a good basis for understanding solubility. A substance with similar characteristics will mix with another...

INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances. Results of these measurements generally...
