- Quite a few folks have told us it's wonderful. Some have complained about
- a few features or lacks thereof, but mostly our customers have been
- pretty happy. The balancing feature you ask about is high on the
- 'Why didn't you do *this*?' list.
-
- Suppose we take Methane and Oxygen. CH4 and O2. What are the products of
- the reaction? That's easy.....carbon dioxide and water. And maybe a little
- carbon monoxide. And some carbonic acid? Possibly some soot, and maybe a
- dash of some obscure double-bonded carbon/oxygen compound.
-
- That's why we don't do equation balancing. If you don't know what you're
- going to get to start with, it's kind of hard to figure out. Assuming you
- do know what you're getting, it will *check* the balance. And it wil *do*
- charge balancing.
-
- Our president and resident chemistry guru (he's even got a doctorate...ooh
- ahh) wrote this pac, and lots of chemistry-knowledgeable folks on the phone
- have told me that they like it. As always, Educalc backs up the stuff they
- sell with a money-back guarantee, so if you decide you hate it you can
- send it back. But I'm pretty sure you won't.
-
- Just my opinion, of course, but feel free to call or write with any
- questions.
