The equation that is balanced is:

2Al+3O2→Al2O3

To determine if an equation is balanced, you need to check if the number of atoms on each side of the equation are equal. Let's analyze each equation to see which one is balanced:

1. Mg+O2→2MgO:
On the left side, there is 1 Mg atom and 2 O atoms. On the right side, there are 2 Mg atoms and 1 O atom. Therefore, this equation is unbalanced.

2. 2Na+F2→2NaF:
On the left side, there are 2 Na atoms and 2 F atoms. On the right side, there are 2 Na atoms and 2 F atoms. This equation is balanced since the number of atoms on each side is equal.

3. 2Al+3O2→Al2O3:
On the left side, there are 2 Al atoms and 6 O atoms. On the right side, there are 2 Al atoms and 3 O atoms. This equation is unbalanced.

4. 2Al+F2→2AlF3:
On the left side, there are 2 Al atoms and 2 F atoms. On the right side, there are 2 Al atoms and 6 F atoms. This equation is unbalanced.

Based on the analysis, the balanced equation is:

2Na+F2→2NaF
