Binary Compounds

Binary Compounds

Chemical compound that contains exactly two different elements

Binary Ionic Compounds

-Compounds in which two types of ions (metal cation and nonmetallic anion) combine to form a ionic compound

-Examples are Calcium chloride (CaCl₂), sodium fluoride (NaF), and magnesium oxide (MgO),

Two types of Binary Ionic Compounds

Type 1: The binary ionic compound in which cation can has only one form (charge), like Na⁺, Mg⁺² and Al⁺³.
Few examples of type 1 binary ionic compounds are as, NaCl, KBr, LiF, CaI₂, AlF₃, MgBr₂ etc.
Type 2: The binary ionic compound in which cation can have the multiple forms (charge), like Fe⁺² and Fe⁺³
Examples of type 1 binary ionic compounds are as FeCl₂ and FeCl₃, AgCl and AgCl_2.

How to name Binary Ionic Compounds

1. Metal (Cation) + NonMetal (anion) –ide

Example:

NaCl

Na – Sodium

Cl – Chlorine

Sodium + Chlorine –idea = Sodium Chloride

2. Use of –ous and –ic

-ous = lower one

-ic = higher one

Example:

FeCl₂ and FeCl₃

FeCl₂ = Ferrous Chloride or Iron (II) Chloride

FeCl₃ = Ferric Chloride or Iron (III) Chloride

Binary Covalent Compounds

-Made from two nonmetal elements. In binary covalent compound sharing of electrons takes place.
-Examples of binary covalent compounds are:  N₂O, P₂O₅, N₂H₄, CH₄ and H₂O.

How to name Binary Covalent Compounds

1.Prefix + Nonmetal  +  Prefix +nonmetal-ide

List of Prefix:

Example:

N₂H₄

Di- nitrogen  +   Tetra- hydrogen –ide

= Dinitrogen Tetrahydride

2.      Use of –ous and –ic

-ous = higher

-ic = lower

Moles

A mole is defined as the number or quantity of a certain substance that has the same measurement of particles as are found in a 12 gram carbon gaining a -12. It follows the number 6.02x10²³ or also known as Avogadro’s number. This states that one mole of a certain element or compound contains 6.02x10²³ molecules of the given compound. 

Calculating the Moles of a compound

(1) Ca - 40.08 – 40.08             In the compound CaCO₃, there are 3 different
(1) C - 12.01 – 12.01               elements namely, Calcium (Ca), Carbon (C), 

(3) O - 16. 00 – 48.00              and Oxygen (O). There are 3 O, 1 C, & 1 Ca. 

                          -------              By getting the mass of each element, we 

                      100.09 u             can calculate their mass in Moles. 1 Ca 

                        CaCO₃                weighs 40. 08, 1 C weighs 12.01, & 3 O's 
                                                                 weigh 48.00,having 100.09 u or mol CaCO₃. 

100. 09 g/mol CaCO₃

_{Mole to Mass, Mass to Mole}

If you want to change the measurement of a certain compound to mole to mass, just change u or mol to g/mol and vise versa for mass to mole.




Exercises
     Calculate the moles of the following compounds and express your final answer with the unit g/mol (unit for mass):

          1. Bi₂O₃

          2. FeSO₄

          3. Ca (CH₃COO)₂

          4. (NH₄)₂Cr₂O₇

          5. AgNO₃

          6. Mg (ClO)₂

          7. Zn (IO4)₂

          8. CH₃ (CH₂)₃ COF

          9. CaSO₄

          10. CuCl₂
