1:2:1
1:1:2
1:1:1
The chemical equation provided is:
Mg + F2 → MgF2.
The coefficients indicate the number of moles of each molecule needed to balance the equation.
In this case, the correct coefficients to balance the equation are:
2 moles of Mg
1 mole of F2
2 moles of MgF2
Therefore, the correct ratio is 2:1:2, which means 2 moles of Mg react with 1 mole of F2 to produce 2 moles of MgF2.
