:d 1. write a balanced chemical equation for each double replacement reaction that occurs. note: compounds with na+, k+, and/or no3− are soluble. 2. why was there no reaction in some of the wells? (see introduction.) 3. how could you tell a ca(no3)2 solution from a zn(no3)2 solution? 4. how could you tell a cu(no3)2 solution from a ni(no3)2 solution?

Pauling and lewis questioned the extreme definitions of bonds. they wondered if bonds might be described somewhere in between the two extremes (covalent and ionic). on the basis of experimental data, pauling confirmed that bonds could be ionic, covalent, and for those, in between, exhibit a degree of ionic character. he theorized that the major factor was how strongly the atoms in the bond attracted the electrons. pauling called this factor - the tendency of an atom to attract electrons in a bond.
