Question

Balance this reaction: underline ( )NaF+underline ( )Br_(2)arrow underline ( )NaBr+underline ( )F_(2)+ 1,2,3,4 21,21 3,1,2,1 1,21,2

Answer 1

To balance the chemical reaction, we need to ensure that the number of atoms of each element is the same on both sides of the equation.The unbalanced reaction is:

Let's denote the coefficients as follows:

We need to find the values of

,

, and

that balance the equation.1. **Balance sodium (Na):** - There is 1 sodium atom on the left side and 1 sodium atom on the right side. - Therefore,

.2. **Balance fluorine (F):** - There are

fluorine atoms on the left side and

fluorine atoms on the right side. - Therefore,

.3. **Balance bromine (Br):** - There are

bromine atoms on the left side and

bromine atoms on the right side. - Therefore,

.Now we have the following relationships:

From

and

, we can express

in terms of

:

Now substitute

into

:

And from

:

So, we have:

Let's choose \(b = simplicity:

Thus, the balanced equation is:

Therefore, the correct coefficients are:

So, the answer is:
