Hi

I suggest using the add-in EquPixy for MS Word.
EquPixy has the following functions for chemists:
- To keyboard chemical elements (Na, Ca, Br, Li ...) without the keys "Shift" or "Caps Lock". Record capital or lowercase letters depend on keystrokes time.
- Figures the number of atoms (H3PO4) makes a subscript, the charges of ions and oxidation states of atoms (Ca2+) makes a superscript.
- An arrow with a special reaction conditions.
- Record substance state, and other information ((g), (aq), (s)). It can be edited.
- Checking the chemical equation (number of elements on the right and left).
