  1. Thanks woelen. This one post taught me more about electrolysis than my AP Chemistry teacher managed to teach me in almost one and a half a semester.
  2. Why is NaOH not Na formed? When salt is dissolved in water NaOH isn't produced is it? From my understanding Na bonds to the electron lobes on oxygen and the hydrogens stay too.
  3. So far everyone said why these courses might be useful, and I'm not denying that they are, but no one addressed the fact that they have absolutely nothing to do with science and do not impact one's understanding of it. You're paying your university for a degree in science, so you should only have to take classes pertinent to it. For twelve years you've been told what you have to study, well after you're eighteen no one should make you do stuff because they think it's good for you. You paid them for a degree in science and they should educate you in it. Only it if you don't want to study other crap. Meh, what the hell do I know.
  4. Hi. I did a lab in chemistry where we put a test tube of paradichlorobenzene in hot water and recorded the temperatures of water and PDB. For the writeup we have to graph the heating curve of PDB, time vs. temperature. One of the questions is; What would the graph look like if the amount of PDB was cut in half? I think that the plateau of the curve would be cut in half because it would take half as much time to melt the PDB, are there any equations that I can use to prove whether this is correct or not?
  5. This is what I expected. Haha! Got any pics? And thanks for replying.
  6. What will happen to a deep sea fish when it's caught in a net and pulled up to shallower water? Will it't eye's blow up and it's blood boil? What about when it's pulled to the surface?
  7. Names of polyatomic ions usually end in -ite or -ate and names of ionic compounds end in the name of the anion in the compound. If the name ends in -ate how can you tell if it's a polyatomic ion or an ionic compound with a polyatomic ion as its anion other than memorizing it? Thanks. Sorry if it's a stupid question.
