Question

Balance the following the chemical equation:

_ Mg + _ F2 → _ MgF2

a
1:1:1
b
2:1:1
c
1:2:1
d
1:1:2

Answer 1

To balance the chemical equation \( \text{Mg} + \text{F}_2 \rightarrow \text{MgF}_2 \), we need to ensure that the number of each type of atom is the same on both sides of the equation.

On the left side:
- We have 1 magnesium (Mg)
- We have 2 fluorine (F) from \( \text{F}_2 \)

On the right side:
- We have 1 magnesium in \( \text{MgF}_2 \)
- We have 2 fluorine in \( \text{MgF}_2 \)

Since there is already 1 Mg and 2 F on both sides, the balanced equation is:

1 Mg + 1 F2 → 1 MgF2

Thus, the coefficients are 1:1:1.

So the correct answer is:
**a 1:1:1**.
