Answer 2

The series of reactions you provided represents the transformation of magnesium (Mg) through several chemical reactions. Here's a breakdown of each step:

1. Mg ➡️ MgO: In this reaction, magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO). The balanced equation for this reaction is: 2 Mg + O2 ➡️ 2 MgO

2. MgO ➡️ MgSO4: In this step, magnesium oxide (MgO) reacts with sulfur trioxide (SO3) to produce magnesium sulfate (MgSO4). The balanced equation for this reaction is: MgO + SO3 ➡️ MgSO4

3. MgSO4 ➡️ Mg(OH)2: This reaction involves the conversion of magnesium sulfate (MgSO4) into magnesium hydroxide (Mg(OH)2). The balanced equation for this reaction is: MgSO4 + 2 NaOH ➡️ Mg(OH)2 + Na2SO4

It's important to note that in the last reaction, sodium hydroxide (NaOH) is typically used as a reactant to precipitate out magnesium hydroxide. The reaction forms magnesium hydroxide and sodium sulfate (Na2SO4) as the byproduct.

Overall, the series of reactions you provided demonstrates the conversion of magnesium (Mg) into magnesium oxide (MgO), then into magnesium sulfate (MgSO4), and finally into magnesium hydroxide (Mg(OH)2).
