24) __F2 + _Nal
What is the coefficients of the product after you find it?

Explanation:

The equation:

           F₂   +    NaI        →     NaF   + I₂

Balancing of chemical equation involves the conservation of species that are reacting on both sides.

To do this, we can set up simple mathematical equations to this regard;

                aF₂   +    bNaI        →     cNaF   + dI₂

a, b, c and d are the coefficients that will balance the equation;

          conserving F;   2a  = c

                             Na;   b = c

                               I;      b  = 2d

       let a  = 1

             c  = 2

            b  = 2

             d  = 1

             F₂   +    2NaI        →     2NaF   + I₂

The coefficients of the products are  2 and 1
