Hi, can anyone explain to me what makes a substance polar/ non-polar? I know it has to do with the bonding, but I'm not quite sure how to explain it in an exam?
Does anyone know of some really good websites or resources available on soaps and industrial chem? Our teacher has just started and he has had to fly through it cause we are way behind. Any help would be much appreciated.
My IT teacher is a fat bitch who sits up the front reading notes from a text book for us to copy down. We also do assignments non stop and when it comes to exam time one of our questions was "how do you clean a laser printer?" Not owning one, along with 90 percent of my class, we didn't answer...
