I'm not big in giving away answers for those doing homework, but I do think that questions with the "homework" tag on them cause, for me at least, a bias against the asker.
This has been brought up in other Stack Exchange sites and there are varying policies across the network. I personally think that the Chemistry SE shouldn't have a homework tag.
Some questions may sound homework-y in nature and so answerers may not wish to help, but I think the askers should be responsible for their own learning. If they want to get all their answers off the Internet and not actually try, that's their choice (and they probably won't do all that well on tests.) If they wish to actually learn, they can take home what they learned through various answers to their question.
I can understand why some of you (or maybe all of you) may disagree with me, but this is just my take on the homework tag.
Note: I'm new to this SE. I didn't want to come in here and be all like, "This is the way it should be," but I noticed a heavy(ish) usage of homework tags. If the homework tag works really well in this SE, then yeah, that's awesome. If the Stack Overflow policy would be a better fit, then we could consider it.
