Question

С соляной кислотой реагирует1) медь2) сульфат магния3) карбонат натрия4) оксид углерода ( IV )5) гидроксид железа ( III )2 варианта ответа

Answer 1

3) карбонат натрия
5) гидроксид железа ( III )

Answer 2

Reactions with Hydrochloric Acid (Соляная кислота)

1) Copper (медь) reacts with hydrochloric acid to produce copper chloride and hydrogen gas. The balanced chemical equation for this reaction is:

   Cu + 2HCl → CuCl2 + H2
   

2) Magnesium sulfate (сульфат магния) does not react with hydrochloric acid. Magnesium sulfate is a stable compound and does not undergo a chemical reaction with hydrochloric acid.

3) Sodium carbonate (карбонат натрия) reacts with hydrochloric acid to produce sodium chloride, water, and carbon dioxide gas. The balanced chemical equation for this reaction is:

   Na2CO3 + 2HCl → 2NaCl + H2O + CO2
   

4) Carbon dioxide (IV) oxide (оксид углерода (IV)) does not react with hydrochloric acid. Carbon dioxide is a stable compound and does not undergo a chemical reaction with hydrochloric acid.

5) Iron (III) hydroxide (гидроксид железа (III)) reacts with hydrochloric acid to produce iron chloride and water. The balanced chemical equation for this reaction is:

   Fe(OH)3 + 3HCl → FeCl3 + 3H2O
   

Based on the given options, the correct answers are:

1) Copper (медь) 3) Sodium carbonate (карбонат натрия)
