Question

review ii
name the following substances.
use lower - case letters for this exercise. if
you need to specify the charge of a
transition metal, you may use roman
numerals within a parenthesis. such as
copper (ii) oxide
ki
fecl₃
n₂o₅

Explanation:

For \(KI\): It is an ionic compound. The cation is \(K^{+}\) (potassium ion) and the anion is \(I^{-}\) (iodide ion). So the name is potassium iodide.
For \(FeCl_{3}\): It is an ionic compound with a transition metal. The cation is \(Fe^{3 +}\) (iron(III) ion) and the anion is \(Cl^{-}\) (chloride ion). So the name is iron(III) chloride.
For \(N_{2}O_{5}\): It is a covalent compound. Using the prefix - naming system for covalent compounds. The prefix for 2 is "di - " and for 5 is "penta - ". So the name is dinitrogen pentoxide.

Answer:

potassium iodide
iron(III) chloride
dinitrogen pentoxide
