Answer 2

Chemical Reactions

1) Алюминий + ортофосфорная кислота: - When aluminum reacts with orthophosphoric acid, it produces aluminum phosphate and hydrogen gas. - The balanced chemical equation for this reaction is: ``` 2 Al + 3 H3PO4 → 2 AlPO4 + 3 H2 ↑ ``` - This reaction is a type of single displacement reaction, where aluminum displaces hydrogen from the acid to form aluminum phosphate and hydrogen gas .

2) Оксид натрия + серная кислота: - The reaction between sodium oxide and sulfuric acid results in the formation of sodium sulfate. - The balanced chemical equation for this reaction is: ``` Na2O + H2SO4 → Na2SO4 + H2O ``` - This is a classic acid-base reaction, where the sodium oxide, a base, reacts with sulfuric acid, an acid, to form sodium sulfate and water .

3) Гидроксид натрия + соляная кислота: - The reaction between sodium hydroxide and hydrochloric acid leads to the formation of sodium chloride (common table salt) and water. - The balanced chemical equation for this reaction is: ``` NaOH + HCl → NaCl + H2O ``` - This is also an acid-base reaction, where sodium hydroxide, a base, reacts with hydrochloric acid to produce sodium chloride and water .

4) Оксид калия + вода: - When potassium oxide reacts with water, it forms potassium hydroxide. - The balanced chemical equation for this reaction is: ``` K2O + H2O → 2 KOH ``` - This is a simple reaction where the oxide reacts with water to produce the hydroxide .

5) Азотная кислота + гидроксид кальция: - The reaction between nitric acid and calcium hydroxide results in the formation of calcium nitrate and water. - The balanced chemical equation for this reaction is: ``` 2 HNO3 + Ca(OH)2 → Ca(NO3)2 + 2 H2O ``` - This is another acid-base reaction, where nitric acid reacts with calcium hydroxide to produce calcium nitrate and water .

6) Кремниевая кислота + оксид бария: - When silicic acid reacts with barium oxide, it forms barium silicate. - The balanced chemical equation for this reaction is: ``` H4SiO4 + BaO → BaSiO3 + 2 H2O ``` - This reaction involves the acid-base reaction between silicic acid and barium oxide to produce barium silicate and water .
