Balancing the Equation: H2 + Br2 = Li + F2

To balance the equation H2 + Br2 = Li + F2 using the method of electronic balancing, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Let's start by balancing the hydrogen (H) atoms. There are 2 hydrogen atoms on the left side and 2 hydrogen atoms on the right side, so hydrogen is already balanced.

Next, let's balance the bromine (Br) atoms. There are 2 bromine atoms on the left side and 1 bromine atom on the right side. To balance the bromine atoms, we need to put a coefficient of 2 in front of Li on the right side. This gives us:

H2 + Br2 = 2Li + F2

Now, let's balance the lithium (Li) atoms. There are 2 lithium atoms on the right side and none on the left side. To balance the lithium atoms, we need to put a coefficient of 2 in front of H2 on the left side. This gives us:

2H2 + Br2 = 2Li + F2

Finally, let's balance the fluorine (F) atoms. There is 1 fluorine atom on the right side and none on the left side. To balance the fluorine atoms, we need to put a coefficient of 2 in front of F2 on the left side. This gives us the balanced equation:

2H2 + Br2 = 2Li + 2F2

Therefore, the balanced equation is 2H2 + Br2 = 2Li + 2F2.
