Question

Mg-MgO-MgSO4-Mg(OH)2-MgO-MgCl2-Mg(NO3)2

Answer 1

Ответ:

Объяснение:

2Mg + O2 = 2MgO

MgO + H2SO4 = MgSO4 + H2O

MgSO4 + 2NaOH = Mg(OH)2↓ + Na2SO4

Mg(OH)2 -> MgO + H2O

MgO + 2HCl = MgCl2 + H2O

MgCl2 + 2AgNO3 = Mg(NO3)2 + 2AgCl↓

Answer 2

The sequence you provided represents a series of reactions involving magnesium (Mg) and various compounds. Let's go through each step:

1. Mg reacts with oxygen (O) to form magnesium oxide (MgO). Mg + O2 → 2MgO

2. Magnesium oxide (MgO) reacts with sulfuric acid (H2SO4) to produce magnesium sulfate (MgSO4) and water (H2O). MgO + H2SO4 → MgSO4 + H2O

3. Magnesium sulfate (MgSO4) reacts with water (H2O) to produce magnesium hydroxide (Mg(OH)2) and sulfuric acid (H2SO4). MgSO4 + 2H2O → Mg(OH)2 + H2SO4

4. Magnesium hydroxide (Mg(OH)2) reacts with magnesium oxide (MgO) to produce magnesium sulfate (MgSO4) and water (H2O). Mg(OH)2 + MgO → 2MgSO4 + H2O

5. Magnesium sulfate (MgSO4) reacts with magnesium chloride (MgCl2) to form magnesium sulfate (MgSO4) and magnesium chloride (MgCl2). MgSO4 + MgCl2 → MgSO4 + MgCl2

6. Magnesium sulfate (MgSO4) reacts with magnesium nitrate (Mg(NO3)2) to form magnesium sulfate (MgSO4) and magnesium nitrate (Mg(NO3)2). MgSO4 + Mg(NO3)2 → MgSO4 + Mg(NO3)2

In summary, the reactions result in the formation of magnesium oxide (MgO), magnesium sulfate (MgSO4), magnesium hydroxide (Mg(OH)2), magnesium chloride (MgCl2), and magnesium nitrate (Mg(NO3)2).
