Dihydrogen monoxide parody Dihydrogen monoxide parody The dihydrogen monoxide parody involves calling water by the unfamiliar chemical name "dihydrogen monoxide" (DHMO), or "hydroxylic acid" in some cases, and listing some of water's well-known effects in a particularly alarming manner, such as accelerating corrosion and causing suffocation. The parody often calls for dihydrogen monoxide to be banned, regulated, and labeled as dangerous. It illustrates how a lack of scientific literacy and an exaggerated analysis can lead to misplaced fears. The parody gained renewed popularity in the late 1990s when a 14-year-old student, Nathan Zohner, collected anti-DHMO petitions for a science project about gullibility. The
Tin(IV) Oxide Tin(IV) Oxide Tin(IV) Oxide, also known as stannic oxide, is the inorganic compound with the formula SnO. The mineral form of SnO is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is an important material in tin chemistry. It is a colourless, diamagnetic, amphoteric solid. Tin(IV) oxide crystallises with the rutile structure. As such the tin atoms are six coordinate and the oxygen atoms three coordinate. SnO is usually regarded as an oxygen-deficient n-type semiconductor. Hydrous forms of SnO have been described as stannic acid. Such materials appear to be
