_ Mg + _ F2 → _ MgF2
Mg + F2 → MgF2
To balance the chemical equation: Mg + F2 → MgF2
Step 1: Count the number of each element on both sides of the equation.
On the left side, we have 1 Mg and 2 F. On the right side, we have 1 Mg and 2 F.
Since the number of Mg atoms is already balanced, we need to balance the number of F atoms.
Step 2: Balance the F atoms by adjusting the coefficients in front of the compounds.
Mg + F2 → MgF2
The coefficient "2" in front of F2 balances the number of F atoms.
The final balanced equation is:
2 Mg + F2 → 2 MgF2
To balance the chemical equation _ Mg + _ F2 → _ MgF2, we need to determine the appropriate coefficients for each compound.
Let's start by balancing the number of magnesium (Mg) atoms. There is one Mg atom on the left side and one Mg atom on the right side:
_Mg + _F2 → _MgF2 (1)
Next, we'll balance the number of fluorine (F) atoms. On the left side, we have two F atoms because there are two F atoms in one F2 molecule. To balance this, we need to put a coefficient of 2 in front of MgF2 on the right side:
_Mg + _F2 → 2MgF2 (2)
Now, we have two Mg atoms on the right side, but only one on the left side. To balance this, we put a coefficient of 2 in front of Mg on the left side:
2Mg + _F2 → 2MgF2 (3)
Finally, we count the number of F atoms on the right side. Each MgF2 molecule has two F atoms, so the total number of F atoms on the right side is 4. To balance this, we need to have four F atoms on the left side. Therefore, we put a coefficient of 2 in front of F2 on the left side:
2Mg + 2F2 → 2MgF2 (4)
Now, the equation is balanced, with two magnesium atoms reacting with two fluorine molecules to produce two molecules of magnesium fluoride (MgF2).
