To balance the chemical equation for the reaction between magnesium (Mg) and fluorine gas (F₂) to produce magnesium fluoride (MgF₂), we start by writing the unbalanced equation:
\[ \text{Mg} + \text{F}_2 \rightarrow \text{MgF}_2 \]
Now, let's count the atoms of each element on both sides of the equation:
- **Reactants:**
- Mg: 1
- F: 2 (from F₂)
- **Products:**
- Mg: 1
- F: 2 (from MgF₂)
At this point, we see that the equation is already balanced because:
- The number of magnesium atoms on the reactant side (1) equals the number of magnesium atoms on the product side (1).
- The number of fluorine atoms on the reactant side (2) equals the number of fluorine atoms on the product side (2).
Thus, the balanced equation is:
\[ \text{Mg} + \text{F}_2 \rightarrow \text{MgF}_2 \]
The coefficients are 1:1:1 for Mg, F₂, and MgF₂ respectively.
So, the correct ratio from your options is **1:1:1**.
\[ \text{Mg} + \text{F}_2 \rightarrow \text{MgF}_2 \]
Now, let's count the atoms of each element on both sides of the equation:
- **Reactants:**
- Mg: 1
- F: 2 (from F₂)
- **Products:**
- Mg: 1
- F: 2 (from MgF₂)
At this point, we see that the equation is already balanced because:
- The number of magnesium atoms on the reactant side (1) equals the number of magnesium atoms on the product side (1).
- The number of fluorine atoms on the reactant side (2) equals the number of fluorine atoms on the product side (2).
Thus, the balanced equation is:
\[ \text{Mg} + \text{F}_2 \rightarrow \text{MgF}_2 \]
The coefficients are 1:1:1 for Mg, F₂, and MgF₂ respectively.
So, the correct ratio from your options is **1:1:1**.
