Answer 1

Ответ:

1) алюминий + ортофосфорная кислота

2Al + 2H₃PO₄ = 2AlPO₄ + 3H₂

2) оксид натрия + серная кислота

Na₂O + H₂SO₄ = Na₂SO₄

3) гидроксид натрия + соляная кислота

NaOH + HCl = NaCl + H₂O

4) оксид калия + вода

2K + 2H₂O = 2KOH + H₂

5) азотная кислота + гидроксид кальция

2HNO₃ + Ca(OH)₂ = Ca(NO₃)₂ + 2H₂O

6) кремниевая кислота + оксид бария

H₂SiO₃ + BaO = BaSiO₃ + H₂O

Answer 2

Chemical Reactions

1) алюминий + ортофосфорная кислота - The reaction between aluminum and orthophosphoric acid results in the formation of hydrogen gas and aluminum phosphate. - The balanced chemical equation for this reaction is: ``` 2Al + 3H3PO4 → 3H2 + 2AlPO4 ``` - 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 - When sodium oxide reacts with sulfuric acid, it forms sodium sulfate. - The balanced chemical equation for this reaction is: ``` Na2O + H2SO4 → Na2SO4 + H2O ``` - This is a classic acid-base reaction, where the oxide reacts with the acid to form a salt and water.

3) гидроксид натрия + соляная кислота - The reaction between sodium hydroxide and hydrochloric acid results in the formation of sodium chloride (common table salt) and water. - The balanced chemical equation for this reaction is: ``` NaOH + HCl → NaCl + H2O ``` - This is another example of an acid-base reaction, where the hydroxide ion from the base combines with the hydrogen ion from the acid to form water, and the remaining ions form the salt.

4) оксид калия + вода - Potassium oxide reacts with water to form potassium hydroxide. - The balanced chemical equation for this reaction is: ``` K2O + H2O → 2KOH ``` - This is a simple reaction where the oxide reacts with water to form the hydroxide.

5) азотная кислота + гидроксид кальция - Nitric acid reacts with calcium hydroxide to produce calcium nitrate and water. - The balanced chemical equation for this reaction is: ``` 2HNO3 + Ca(OH)2 → Ca(NO3)2 + 2H2O ``` - This is another acid-base reaction, where the acid and base react to form a salt and water.

6) кремниевая кислота + оксид бария - The reaction between silicic acid (silicon dioxide) and barium oxide results in the formation of barium silicate. - The balanced chemical equation for this reaction is: ``` BaO + SiO2 → BaSiO3 ``` - This is a type of synthesis reaction, where two substances combine to form a more complex product [[6]].
