Question

Mg → MgSO4 → Mg(OH)2 → Mgo → Mgc

Answer 1

1. Mg + H2SO4=MgSO4 +H2

2.MgSO4 + 2KOH= Mg(OH)2 + K2SO4

3. Mg(OH)2 =(t) MgO +H2O

4. а четвертую реакцию помоему неправильно написали.. вот два варианта:

MgO + H2S= MgS + H2O

MgO + 2HCl = MgCl2 + H2O

а как там написано с углеродом не получается.

 

Answer 2

Chemical Reaction: Mg → MgSO4 → Mg(OH)2 → Mgo → Mgc

The given chemical reaction involves the transformation of magnesium (Mg) through several compounds: magnesium sulfate (MgSO4), magnesium hydroxide (Mg(OH)2), magnesium oxide (MgO), and finally, magnesium carbide (MgC).

To provide a detailed explanation of each step in the reaction, let's break it down:

1. Mg → MgSO4: - In this step, magnesium (Mg) reacts with sulfuric acid (H2SO4) to form magnesium sulfate (MgSO4). - The balanced chemical equation for this reaction is: Mg + H2SO4 → MgSO4 + H2O. - The reaction involves the displacement of hydrogen (H) from sulfuric acid by magnesium (Mg). - The resulting product is magnesium sulfate (MgSO4) and water (H2O).

2. MgSO4 → Mg(OH)2: - In this step, magnesium sulfate (MgSO4) reacts with sodium hydroxide (NaOH) to form magnesium hydroxide (Mg(OH)2) and sodium sulfate (Na2SO4). - The balanced chemical equation for this reaction is: MgSO4 + 2NaOH → Mg(OH)2 + Na2SO4. - The reaction involves the displacement of sodium (Na) from sodium hydroxide by magnesium sulfate. - The resulting product is magnesium hydroxide (Mg(OH)2) and sodium sulfate (Na2SO4).

3. Mg(OH)2 → Mgo: - In this step, magnesium hydroxide (Mg(OH)2) undergoes a dehydration reaction to form magnesium oxide (MgO) and water (H2O). - The balanced chemical equation for this reaction is: Mg(OH)2 → MgO + H2O. - The reaction involves the removal of water molecules from magnesium hydroxide. - The resulting product is magnesium oxide (MgO) and water (H2O).

4. Mgo → Mgc: - In this step, magnesium oxide (MgO) reacts with carbon (C) to form magnesium carbide (MgC). - The balanced chemical equation for this reaction is: MgO + C → MgC + CO. - The reaction involves the displacement of oxygen (O) from magnesium oxide by carbon. - The resulting product is magnesium carbide (MgC) and carbon monoxide (CO).

Please note that the specific reaction conditions, such as temperature, pressure, and catalysts, may affect the reaction rates and yields. The given reaction sequence represents a general overview of the transformation of magnesium through the mentioned compounds.
