Looking at the elements in the equations, we can see that the only element that is not balanced is S. On the left side, we have 2S in the first term and 13S in the second term, giving us a total of 15S. On the right side, we have 12S in both terms, giving us a total of 24S. Therefore, we need to add 9S to the left side to balance the equation. The only answer choice that provides a coefficient of 9 for S is C, with a missing number of 5.
