1. INORGANIC COMPOUNDS OXIDES

2. Classification of the chemical compounds
Organic
Inorganic:
OXIDS
ACIDS
HYDROXIDES AND BASES
SALTS
COMPLEX COMPOUNDS

3. OXIDS
Binary oxides represent compounds of oxygen (oxygen is bound to a metal, non-metal, semimetal) in which Oxidation number of oxygen is -2.
Separation of oxides - according to properties:
Acids,
Bases,
Amphoteric,
Indifferent (neutral)

4. OXIDS
Acid oxides are oxides that react with hydroxide (bases) or base oxides and thus form salts and water form acids.
Example: (CO2, SO2, NO, P2O5)
CO2 + Ca(OH)2 → CaCO3 + H2O
CO2 + CaO → CaCO3
SO3 + H2O → H2SO4
CO2 + H2O →H2CO3
Acid oxides can arise with deprivation of water from acids, therefore still called anhydride acid (acid without water)
Example: CO2 anhydride carbonic acid H2CO3
SO3 anhydrous sulfuric acid H2SO4

5. Oxides
Base oxides are oxides that react with acids or acid form and oxides thereof and water form bases.
For example:(CaO, Cu 2 O, CuO, Fe 2 O 3, )
CuO + H2SO4 → CuSO4 + H2O
CaO + CO2 → CaCO3
CaO + H2O → Ca (OH) 2
Na2O + H2O → 2NaOH

6. Oxides
Amphoteric oxides are oxides that under certain conditions apply as acid and basic oxides (react with acids and bases).
: (ZnO, Al2O3, SnO, Sb2O3, PbO, .)
ZnO + 2HCl → ZnCl2 H2O +
ZnO + 2NaOH + H2O = Na2 [Zn (OH) 4]
Indifferent (neutral) oxides are those oxides which do not react with either acids or with bases or water.
Example: (CO, NO, N2O, )

7. Oxides -Nomenclature oxides -Nomenclature of metal (base) oxide
If metal built only one type oxide or metal if there is only one possible oxidation state, then the name of the oxide form of the name of the metal by adding the word "oxide".
Example: Sodium oxide Na2O
Calcium oxide CaO
Aluminum oxide Al2O3
If the metal has more possible oxidation states (variable valence), that builds more kinds oxides, then between the name of the metal oxide and the word write the oxidation state of the metal with Roman number placed in parenthesis, merged with the name of the metal.

8. OXIDES examples: Cu2O copper (I) oxide CuO copper (II) oxide
FeO iron (II) oxide
Fe2O3 iron (III) oxide
Look out! The name of the metal and the Roman numbers are merged write the name of the metal (with or without roman number) and write the word oxide separated.
Nomenclature of non-metallic (acid) oxide
Name of non-metal oxide in addition to the previous method, can be formed from the name of the metal and the word "oxide". Before the name of nonmetal before the word oxide are added prefixes that mark the appropriate stoichiometric index named in Greek

9. OXIDES examples: N2O5 dinitrogen pentoxide Sulfur trioxide SO3
P4O10 tetraphosphoric dekaoksid

10. OXIDES Being oxides Mainly oxides can be obtained in two ways:
a.Direct bonding of elementary substance with oxygen
Examples: 2Mg + O2 = 2MgO
S + O2 = SO2
b. The decomposition of complex salts or compounds
Examples: CaCO3 = CO2 + CaO
