Question

Mg - MgO, MgSO4 - MgO - Mg(OH)2 – MgO – MgCl2​

Answer 1

Ответ:

2Мg+O2=2MgO

MgO+H2SO4=MgSO4+H2O

MgO+H2O=Mg(OH)2

Answer 2

Ответ:

2Mg + O2 = 2MgO

MgO + H2SO4 = MgSO4 + H2O

2MgSO4 + O2 = 2MgO + 2SO2 + 2O2

MgO + H2O = Mg(OH)2

2Mg(OH) 2 + O2 = 2MgO + 2H2O

MgO + 2HCl = MgCl2 + H2O

Answer 3

It seems like you've provided a sequence of chemical reactions involving magnesium (Mg) and various compounds. Let me break down these reactions step by step:

1. Mg - MgO: This is likely the combustion of magnesium (Mg) in the presence of oxygen (O2) to form magnesium oxide (MgO). The balanced chemical equation for this reaction is:

   2Mg + O2 → 2MgO

   In this reaction, magnesium reacts with oxygen to produce magnesium oxide.

2. MgSO4 - MgO: In this step, it appears that you are starting with magnesium sulfate (MgSO4) and converting it to magnesium oxide (MgO). This could be done by heating magnesium sulfate to high temperatures. The chemical reaction would be:

   MgSO4 (heated) → MgO + SO3

   The magnesium sulfate decomposes into magnesium oxide and sulfur trioxide.

3. MgO - Mg(OH)2: It seems like you want to convert magnesium oxide (MgO) to magnesium hydroxide (Mg(OH)2). This can be done by adding water (H2O) to magnesium oxide. The chemical reaction is:

   MgO + H2O → Mg(OH)2

   Magnesium oxide reacts with water to produce magnesium hydroxide.

4. MgO - MgCl2: This step suggests converting magnesium oxide (MgO) to magnesium chloride (MgCl2). To do this, you would need to react magnesium oxide with hydrochloric acid (HCl). The chemical reaction is:

   MgO + 2HCl → MgCl2 + H2O

   Magnesium oxide reacts with hydrochloric acid to produce magnesium chloride and water.

So, in summary, you have a sequence of reactions starting with magnesium (Mg) and different compounds, leading to the formation of magnesium oxide (MgO), magnesium hydroxide (Mg(OH)2), and magnesium chloride (MgCl2) through various chemical processes. These reactions involve the use of heat and chemical reactions to transform the compounds.
