Classification of Inorganic Substances

To classify the given inorganic substances, let's analyze each one based on the provided categories:

а) Kislotnyy oksid (acidic oxide): An acidic oxide is an oxide that reacts with water to form an acid. Some examples of acidic oxides are sulfur dioxide (SO2), sulfur trioxide (SO3), phosphorus pentoxide (P2O5), nitrogen dioxide (NO2), and carbon dioxide (CO2).

б) Osnovnoy oksid (basic oxide): A basic oxide is an oxide that reacts with water to form a base. Examples of basic oxides include sodium oxide (Na2O), potassium oxide (K2O), calcium oxide (CaO), and magnesium oxide (MgO).

в) Kislota (acid): An acid is a substance that donates protons (H+) when dissolved in water. Examples of acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid (HNO3), and carbonic acid (H2CO3).

г) Osnovanie (base): A base is a substance that accepts protons (H+) when dissolved in water. Examples of bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), calcium hydroxide (Ca(OH)2), and magnesium hydroxide (Mg(OH)2).

д) Sol' (salt): A salt is a compound formed when an acid reacts with a base, resulting in the neutralization of the acid and base. Examples of salts include sodium chloride (NaCl), barium chloride (BaCl2), lead nitrate (Pb(NO3)2), and zinc nitrate (Zn(NO3)2).

Based on this classification, the given substances can be categorized as follows:

а) Kislotnyy oksid (acidic oxide): Sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon dioxide (CO2).

б) Osnovnoy oksid (basic oxide): Calcium oxide (CaO) and magnesium oxide (MgO).

в) Kisloty (acids): Hydrobromic acid (HBr) and sulfurous acid (H2SO3).

г) Osnovaniya (bases): Barium hydroxide (Ba(OH)2) and magnesium hydroxide (Mg(OH)2).

д) Soli (salts): Sodium chloride (NaCl), lead(II) oxide (PbO), calcium (Ca), barium hydroxide (Ba(OH)2), zinc nitrate (Zn(NO3)2), and aluminum (Al).

Please note that the classification of substances can vary depending on the context and specific definitions used. The provided classification is based on the general understanding of these substances.
