how do you identify spectator ions in redox equations?
I understand everything about redox equations like oxidation and reduction how to balance them. Balance the electrons and balance them in acidic and basic solution. But how do you identify spectator ions? Like I know that when an element such as Na is attached to dichromate =
Na2Cr2O7 -2 we must eliminate the Na. I know this but how about this problem:
AuCl3 + NaI > Au + I2 + NaCl

my teacher eliminated all Cl and Na
so AU + I > Au + I2 (why??? eliminate Na and Cl is it because they dont change oxidation states in the reaction???)

why does this occur? ANY help please would be great

Ok so for my AP US history class we are required to bring in a discussion question that we are graded on, here is the question: How did Jefferson's Louisiana Purchase transform America's understanding of itself and its future? Was it inevitable that the west would become part of a much greater United States, or was their real danger in efforts like Aaron Burr's to break areas off from the rest of the country?


any help is appreiated. thanks =]

There has got to be a way for him to learn how to enjoy reading, but we haven't figured it out yet! He's very smart, and reads at an 8th grade level. His school does the accelerated reading program, so he has to read at least 2 chapter books a week. It's like pulling teeth! We take turns reading, and that works for a little while. The next day - back to hating it. Any ideas? Help!!! Thanks!!
