CHEMISTRY help - chemical reactions, etc... please...

***Fully Flared*** · 05-14-2008, 10:13 PM

I've got a project to do... have to have 2 chemical reactions, one with a polyatomic ion in it and the other with the sum of the coefficients being 10 or greater. Now the latter isn't so hard, but I really cannot think of a chemical reaction (im thinking double replacement, of course) using polyatomic ions... any help? invisible rep to all who help, I'd really appreciate it.

or even just a place to look for them online, cannot find one using google or whatnot.
