I know this really has to do with the nomenclature of molecules covered in Chapter 4, but I think you will find this interesting. The official IUPAC (systematic) name for water should be dihydrogen monoxide. There has been an “urban legend” spread about dihydrogen monoxide via numerous emails and web pages. Google “dihydrogen monoxide” and review at least three of these web pages (make sure you reference them). Summarize your findings and provide an evaluation or an opinion. You can start with:
