Balance the following the chemical equation:
_ Mg + _ F2 → _ MgF2
a
1:1:1
b
1:2:1
c
2:1:1
d
1:1:2
The correct way to balance the chemical equation is:
1 Mg + 1 F2 → 1 MgF2
So the answer is a) 1:1:1.
To balance the chemical equation _ Mg + _ F2 → _ MgF2, you need to ensure that there are the same number of each type of atom on both sides of the equation.
Let's start by counting the number of atoms for each element on both sides:
On the left side, we have 1 magnesium (Mg) atom and 2 fluorine (F) atoms.
On the right side, we have 1 magnesium (Mg) atom and 2 fluorine (F) atoms.
Since the number of magnesium (Mg) atoms is already balanced, we only need to balance the number of fluorine (F) atoms.
Looking at the options provided:
a) 1:1:1
b) 1:2:1
c) 2:1:1
d) 1:1:2
To balance the number of fluorine (F) atoms, we choose option b) 1:2:1. This means we need 1 magnesium (Mg) atom, 2 fluorine (F) atoms, and 1 magnesium fluoride (MgF2) molecule to achieve a balanced equation.
Therefore, the balanced chemical equation is:
1 Mg + 2 F2 → 1 MgF2
To balance the chemical equation Mg + F2 → MgF2, we need to ensure that there is an equal number of each type of atom on both sides of the equation.
Based on the given options, the correct coefficients to balance the equation are:
a) 1:1:1 (not balanced)
b) 1:2:1 (not balanced)
c) 2:1:1 (balanced)
d) 1:1:2 (not balanced)
Therefore, the correct answer is c) 2:1:1, which means the balanced equation is:
2 Mg + F2 → 2 MgF2
