Balance the following the chemical equation:

Question

_ 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 $\text{Mg}+{\text{F}}_2\to {\text{MgF}}_2$, 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.
