We aren't awarded with the best chemistry teacher as well (although I'm not from US), she can't handle the class (well that's not really her responsibility, but other teachers manage to do it) nor she has the interest in trying. If we have a chemistry test and someone asks a questions about the exercise FROM THE TEST the teacher is more than glad to help during the test (not sure if that's a bad quality for everyone tho
). Or for example there was an exercise in the papers we've been given for homework which sounded something like this "4 alloyed ampoules in room temperature are filled with a) hydrogen, b) ozone c) water d) ammonia. Which ampoule has the most molecules?" so she said that she wouldn't rate this exercise, since in her opinion somebody made a mistake, because we were speaking about gases and ideal conditions and etc, and she said it's weird for the authors to create such exercise if everywhere in the book it was written that the same amount of gases in the same volume have the same number of molecules, I then explained to her that water is not a gas, and since it's room temperature water is A LIQUID and the ampoule filled with water has the most molecules, and her response was "still, doesn't make any sense. I don't know... I'm still not going to rate this exercise".
I know she's going to leave in a few months, I'm kinda glad about that, but also sad a bit, cos I've come to like her, because she's sweet no matter what.
