1) The program does not accept decimal coefficients. So no H<sub>2</sub> + 0.5O<sub>2</sub>
= H<sub>2</sub>O ! I've never liked decimal coefficients, so I don't use them, and didn't want to take the effort to code it in. Just
multiply your equations!
2) Equations must be entered in the format A + B = C + D. Plus signs, a single equals sign, and spaces. Spaces aren't critical (if you omit them, the
display gets weird but the calculations still work), but the format of the + and = does matter.
3) Capitalization matters. Otherwise your nitric oxide (NO) might be interpreted as nobelium (No). Write your formulas properly!
