Redox

It's been far too long since I last posted for my grade to still be considered "ok." I'm not really worried with whether people think it's ok or not though. I don't really feel like letting my happiness rely on numbers, so.. Ok, science! Ugh, um, redox. That covers single replacement reactions, I believe. So, there's precipitate, acid base, redox (?), and some other fourth thing. Maybe redox was split into two. Does anyone even look at this anymore? Bleh..
