What is the product when Mg react with `SO_(2)` ?

Options

A. Mg O
B. `MgSO_(4)`
C. Mg S
D. Both (1) & (3)

Answer

To determine the products when magnesium (Mg) reacts with sulfur dioxide (SO₂), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are magnesium (Mg) and sulfur dioxide (SO₂).

### Step 2: Write the Reaction
The initial reaction can be written as:
\[ \text{Mg} + \text{SO}_2 \rightarrow ? \]

### Step 3: Determine Possible Products
When magnesium reacts with sulfur dioxide, it can produce magnesium oxide (MgO) and magnesium sulfide (MgS).

### Step 4: Analyze Oxidation States
- In elemental magnesium (Mg), the oxidation state is 0.
- In sulfur dioxide (SO₂), sulfur has an oxidation state of +4 and oxygen has an oxidation state of -2.
- In magnesium oxide (MgO), magnesium has an oxidation state of +2 and oxygen remains -2.
- In magnesium sulfide (MgS), sulfur has an oxidation state of -2 and magnesium remains +2.

### Step 5: Identify Oxidation and Reduction
- Magnesium is oxidized from 0 to +2 (loss of electrons).
- Sulfur is reduced from +4 in SO₂ to -2 in MgS (gain of electrons).
This indicates that the reaction is a redox reaction, where magnesium acts as the reducing agent and sulfur dioxide acts as the oxidizing agent.

### Step 6: Write the Balanced Equation
To balance the reaction, we can write:
\[ 2\text{Mg} + \text{SO}_2 \rightarrow \text{MgO} + \text{MgS} \]

### Step 7: Conclusion
The products of the reaction between magnesium and sulfur dioxide are magnesium oxide (MgO) and magnesium sulfide (MgS). Therefore, the correct answer is that both MgO and MgS are formed.

### Final Answer
The products when magnesium reacts with sulfur dioxide are both MgO and MgS.
