Question

Осуществите следующие превращения: Mg->MgSO4->Mg(OH)2->MgO

Answer 1

FeSO4 + Mg ----> MgSO4 + Fe
MgSO4 + 2KOH ---> Mg(OH)2 + K2SO4
Mg(OH)2 ---t---> MgO + H2O

Answer 2

Conversion of Mg to MgSO4

To convert Mg to MgSO4, we need to react magnesium with sulfuric acid (H2SO4). The reaction can be represented as follows:

Mg + H2SO4 → MgSO4 + H2

In this reaction, magnesium (Mg) reacts with sulfuric acid (H2SO4) to produce magnesium sulfate (MgSO4) and hydrogen gas (H2).

Conversion of MgSO4 to Mg(OH)2

To convert MgSO4 to Mg(OH)2, we need to react magnesium sulfate with a base such as sodium hydroxide (NaOH). The reaction can be represented as follows:

MgSO4 + 2NaOH → Mg(OH)2 + Na2SO4

In this reaction, magnesium sulfate (MgSO4) reacts with sodium hydroxide (NaOH) to produce magnesium hydroxide (Mg(OH)2) and sodium sulfate (Na2SO4).

Conversion of Mg(OH)2 to MgO

To convert Mg(OH)2 to MgO, we need to heat magnesium hydroxide. The reaction can be represented as follows:

Mg(OH)2 → MgO + H2O

In this reaction, magnesium hydroxide (Mg(OH)2) decomposes upon heating to produce magnesium oxide (MgO) and water (H2O) [[1]](https://library.pguas.ru/xmlui/bitstream/handle/123456789/302/%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F%20%D0%9F%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B0%20%D0%BA%D1%83%D1%80%D1%81%D0%B0%206-%D0%B5%20%D0%B8%D0%B7%D0%B4.pdf?sequence=1&isAllowed=y).

So, the complete series of transformations is as follows: Mg → MgSO4 → Mg(OH)2 → MgO
