Just want to say couple of words to devs regarding that chemistry quiz.
I don't know what school you taught, but in Russia, for comparison, no chemistry teacher will ask alchemical names of chemical matters. It is additional material, that can be used in interschool contest (so-called school Olympics), not as part of a lesson.
Moreover, after that question teacher (why she is a professor? Professors don't teach in school) ask the easiest question in all quiz, even children knows that acid burns. But if you can't guess correct answer on previous, much harder questions, you won't see the last question. Why questions are not in line from easy to hard? I did in my school (it was years ago, in last millenia) better quiz than that.
Another thing, if you are so in love with chemistry, ask right questions. Or give players possibility to choose answer from the list. If you ask what I get if I mix sulfuric acid with base then salt is a correct answer. But, alas, it's not. Because right answer is sulfate. Devs, are you want to tell us by any chance that sulfate is not a salt?
