Iodine pentafluoride gas reacts with iodine fluoride gas producing iodine heptafluoride gas and iodine gas. Answer the following questions about this reaction. a. (6 pts) Fill in the missing information for the balanced chemical reaction.

Explanation:

The objective is to show the balanced chemical equation.

1. Word equation (given):

                                                    → iodine heptafluoride gas + iodine gas

2. Chemical formulas for every substance:

Iodine pentafluoride gas:

Iodine fluoride gas

Iodine heptafluoride gas

Iodine gas:

2. Write the molecular equation

3. Write the balanced chemical reaction

Add the coefficients to show the same number of atoms of a kind on each side of the chemical equation:

To balance F, add a 2 in front of IF(g):

Iodine is balanced.

Check:
