Make up the formulas of the higher oxides of chemical elements of the second period and indicate the nature of their properties (basic, amphoteric, acidic). Illustrate with reaction equations the properties of oxides of lithium, beryllium and carbon (4). What are the properties of the corresponding hydroxides?

Li2O – lithium oxide – basic oxide.
Li2O corresponds to LiOH – base.
How the basic oxide reacts with water, acidic oxides, acids.
Li2O + H2O = 2LiOH.
Li2O + CO2 = Li2CO3.
Li2O + 2HCl = 2LiCl + H2O.
BeO – beryllium oxide – amphoteric oxide.
Beryllium oxide corresponds to Н2ВеО2 – beryllium acid.
It reacts as a basic oxide with acids, and as an acidic oxide – with bases.
BeO + H2O = Be (OH) 2 (beryllium hydroxide).
BeO + 2NaOH = Na2BeO2 + H2O (sodium berylate and water).
BeO + 2HCl = BeCl2 + H2O (beryllium chloride and water).
B2O3 – boron oxide – acidic oxide.
Boron hydroxide – boric acid B (OH) 3 – H3BO3.
CO2 – carbon monoxide (IV) – acidic.
As an acidic oxide, it reacts with water, bases and basic oxides.
К2O + CO2 = К2CO3.
H2O + CO2 = H2CO3.
2NaOH + CO2 = Na2CO3
Hydroxide Н2СО3 – carbonic acid.
N2O5 – nitric oxide (V) – acidic.
Hydroxide – nitric acid HNO3.
OF2 is oxygen fluoride, not an oxide.
