Most people can balance equations fairly quickly.  It still would save time,
and I imagine quite a bit.  I suppose when I referred to predicting
reactions, I was too ambiguous.  It is impossible without relying on complex
quantum mechanics(redundant ;-) to predict products, however you can still
get a decent idea for most inorganic reactions.  Just decide if its a double
displacement, single replacement, combustion, etc. and balance for that
type.
For example:
HCl + NaOH -> HOH [H2O] +NaCl
or
CH4 + O2 ->  CO2 +2H2
You're making some assumptions, but useful & pretty accurate ones.

I'm curious, what's the 86 program do?

I'd be willing to pseudo-code some algorithms for the stuff I've talked
about if you'd(and your partner) like to put it into TI-86 source code?
