balance the following the chemical equation: _ mg + _ f₂ → _ mgf₂ (1 point) o 1:1:2 o 1:2:1 o 1:1:1 o 2:1:1

Explanation:

Step1: Count atoms on both sides

On the left - hand side, we have 1 Mg atom and 2 F atoms in $F_2$. On the right - hand side, in $MgF_2$, we have 1 Mg atom and 2 F atoms.

Step2: Determine coefficients

Since the number of Mg and F atoms is already equal on both sides of the equation, the coefficients are 1 for Mg, 1 for $F_2$, and 1 for $MgF_2$.

Answer:

1:1:1
