Answer:

C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2

Explanation:

An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.

The unbalanced reaction:

Iā‚‚ + Oā‚‚ -----> Iā‚„Oā‚‰

Reactants: 2 iodine, 2 oxygen

Products: 4 iodine, 9 oxygen

The balanced equation:

4 Iā‚‚ + 9 Oā‚‚ -----> 2 Iā‚„Oā‚‰

Reactants: 8 iodine, 18 oxygen

Products: 8 iodine, 18 oxygen

Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.
