I need a little bit of help here. I ate some four year old chocolate syrup (Hersheys) will I be okay? It expired in nov of 2009.

I have some household ammonia that I will be using for a chemistry project (making ferrofluid), but I am concerned because the ammonia I have is scented and yellow colored. Will this still work?

I bought some oleic acid the other day and had it shipped to me. It arrived frozen, and when thawed it turned yellow. Is there something wrong with it?
