In the image below, you can see two rectangles with some text inside. If you take a closer look you will notice a difference in spacing between lines. The spacing between the first and the second lines is smaller than the spacing between the second and the third.

The last line is always separated. If you have 10 lines of text, the spacing between all the lines will be OK except the spacing between the next to last and the last line of text.
The font is the same (in every aspect) accross the lines (except the title), and there are no custom paragraph properties set.

Why does this happen and how to solve this?




Question: #NAME?
Answer: Cobalt may possibly have all those other oxidation states (and others too) for this nomenclature system, we only care about the two most common oxidation states in ionic compounds: $\ce{Co^{2+}}$ and $\ce{Co^{3+}}$. Cobalt(II) compounds would thus be named  cobaltous and cobalt(III) compounds would be cobaltic. Which is yours?
