Question

выполнить цепочку превращений MgCO3=>MgCl2=>Mg(OH)2=>MgSO4

Answer 1

MgCO3  + 2HCl=> H2O + CO2 + MgCl2

MgCl2 + 2KOH = Cl2 + Mg(OH)2 + 2KCl

Mg(OH)2 + H2SO4 =  MgSO4 + 2H2O

Answer 2

1)MgCO3+2Cl=MgCl2+CO3 - реакция замещения

2)MgCl2+2NaOH=Mg(OH)2+ 2NaCl - реакция обмена

3)Mg(OH) + H2SO4=MgSO4+H2O - реакция обмена

Answer 3

Conversion of MgCO3 to MgCl2

To convert MgCO3 (magnesium carbonate) to MgCl2 (magnesium chloride), we can use the following reaction:

MgCO3 + 2 HCl → MgCl2 + H2O + CO2

In this reaction, magnesium carbonate reacts with hydrochloric acid to produce magnesium chloride, water, and carbon dioxide.

Conversion of MgCl2 to Mg(OH)2

To convert MgCl2 to Mg(OH)2 (magnesium hydroxide), we can use the following reaction:

MgCl2 + 2 NaOH → Mg(OH)2 + 2 NaCl

In this reaction, magnesium chloride reacts with sodium hydroxide to produce magnesium hydroxide and sodium chloride.

Conversion of Mg(OH)2 to MgSO4

To convert Mg(OH)2 to MgSO4 (magnesium sulfate), we can use the following reaction:

Mg(OH)2 + H2SO4 → MgSO4 + 2 H2O

In this reaction, magnesium hydroxide reacts with sulfuric acid to produce magnesium sulfate and water.

Therefore, the complete chain of transformations from MgCO3 to MgSO4 is as follows:

MgCO3 → MgCl2 → Mg(OH)2 → MgSO4

Please note that the reactions mentioned above are just examples of possible reactions. The actual reaction conditions and specific reagents used may vary depending on the desired outcome and the specific reaction conditions.
