Answer 2

It appears you've listed a series of chemical reactions involving magnesium (Mg) and its transformation into different compounds. Let me break down each step for you:

1. Mg → MgO: In this step, magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO). This is a common oxidation reaction that occurs when magnesium metal is exposed to oxygen in the air. The balanced chemical equation for this reaction is:

   2Mg + O2 → 2MgO

2. MgO → MgSO4: It seems there might be a missing step between MgO and MgSO4. To convert magnesium oxide (MgO) into magnesium sulfate (MgSO4), you typically need to react MgO with sulfuric acid (H2SO4). Here's the balanced chemical equation for the formation of magnesium sulfate from magnesium oxide and sulfuric acid:

   MgO + H2SO4 → MgSO4 + H2O

   This reaction produces magnesium sulfate and water.

3. MgSO4 → Mg(OH)2: In this step, magnesium sulfate (MgSO4) is reacting with a base (likely sodium hydroxide, NaOH, or another hydroxide source) to form magnesium hydroxide (Mg(OH)2). Here's the balanced chemical equation:

   MgSO4 + 2NaOH → Mg(OH)2 + Na2SO4

   This reaction results in the formation of magnesium hydroxide and sodium sulfate.

So, the overall sequence of reactions is as follows:

1. Mg → MgO (oxidation with oxygen)
2. MgO + H2SO4 → MgSO4 + H2O (reacting with sulfuric acid)
3. MgSO4 + 2NaOH → Mg(OH)2 + Na2SO4 (reacting with sodium hydroxide)

Each step represents a chemical transformation of magnesium into different compounds.
