Guideline #3 Tasks #11 & #12 Study Guide
For tasks #11 & #12,
Inorganic Compounds, we randomly mix the compounds from Guidelines 1, 2, 3, &5. And call these exercises Inorganic Names and Formulas Exercises:
The
key to deciding which system to use is to look at the element written first
And classify the compound:
if Metallic then ionic: Ca3(PO4)2 Calcium
phosphate
if nonmetal then molecular: CO2 Carbon Dioxide
if hydrogen & (aq) then acid HNO3 Nitric Acid
a. Ionic*(Binary or Ternary) : Metallic Cation + Nonmetallic Anion
b. Molecular (Binary): Nonmetal-Nonmetal
bonded by covalent bonds
c. Acids
(aq) (Binary or Ternary): Hydrogen + Nonmetallic
anion
(in aqueous solution)
Task #11: Inorganic Compound Names
Task #12: Inorganic Compound Formulas
Inorganic
Compound Examples:
Using a
periodic chart write the names or formulas of the following polyatomic ions
depending on whether the formula or name is given (After answer is the
classification of the inorganic compound):
(Common Name Guideline 4: Epson Salts)
(not
sulfite! Why?)
7. HF ___________Hydrofluoric acid______
(Binary Acid)
(Common Name Guideline 4: antacid Maalox)
(Common Name Guideline 4: Bleach)
14. Sodium
Hydroxide ______NaOH_______
_ (Ternary Salt [base])
15. Hydrochloric acid(aq) ______HCl_________ (Binary Acid)
