my book's copyright is from 2010. I got it in 2011 from the tbr website, and it was the most recent book at the time. In the book, the problem is for c6h12o6(s) + o2(g) -> co2(g) + h2o(g). Maybe you have a more recent edition, but in my book the error exists. I am looking at it right now.
Edit: I should say that i do not think the tbr books are worthless. They have some good tips for speeding up your problem solving and some good memory tricks for certain problem types. I like the depth to which they cover material. I still use my textbooks to be sure about some things, but the depth of the books works well for me as a guide to show me how deeply to study a topic. I also like the passages despite the typos. If i thought the errors were enough to invalidate the good parts of the books i would have already asked for a refund, but that is not the case.
