(a) Cu(C2H3O2)2 (an ionic compound)
From the chemical formula of the ionic compound, identify its component ions and their names. (Type the names of the ions.)Cu(C2H3O2)2 contains __________________ (Cu2+) ions and ___________________ (C2H3O2−) ions.
Name the following ionic compounds.
(a) Ir(ClO4)3(b) Li2CrO4(c) Cu3P2
Fill in the blank with the appropriate response:
Recall the definitions of a cation and an anion, and indicate how they are combined to form ionic compounds.An ionic compound is composed of cations, which are ____________________ (positively or negatively) charged ions, and anions, which are ____________________ (positively or negatively) charged ions. The cation or anion can be (1) monatomic, where the charge is on each individual atom of an element, or (2) polyatomic, where the charge is on a chemically bonded group of two or more atoms.When a cation and an anion combine to form an ionic compound, their ratio is such that the total positive charge balances…
