Dihydrogen+Monoxide

=Dihydrogen Monoxide= Dihydrogen Monoxide (DHMO) is the chemical nomenclature for a substance that more commonly goes under the title of water, or H2O. It is a substance that can also go under names like:
 * Dihydrogen Oxide
 * Hydrogen Hydroxide
 * Hydronium Hydroxide
 * Hydric Acid

In its pure form, this substance is clear and and odorless. At room temperature, this substance is liquid, though is freezes into a solid at 0 degrees Celsius, and boils and evaporates at 100 degrees celsius. The density of water in solid form is 1 g/mL, and is unique in the way that as it becomes cooler, the volume of water expands. In chemical structure, this molecule is composed of two hydrogen molecules and one oxygen molecule. It is a polar, bent molecule that is connected through covalent bonds.

DHMO covers approximatly 70.9% of the earth's surface, and is the substance that defines earth from all other known planets in the universe. In more specific terms, water can be divided into categories including freshwater, groundwater, glacier water, and ocean water. Ocean water makes up 96.5% of the water on earth, with 2.14% contained in groundwater and glacier sources. The remaining 2.5% is freshwater that is available and ready to sustain life.=====

Dihydrogen Monoxide is circulated throughout the planet by a cycle known as the water cycle, which is a balance between the evaporation and condensation of water contained in liquid forms on the planet and in gaseous forms in the atmosphere. In short, water evaporates under heat from the sun and collects in the atmosphere to form clouds, whereupon the water is subsequently expelled out of the atmosphere via condensation as it is precipitated through various forms such as rain, snow, or sleet.

DHMO Hoax
The hoax essentially consists of a list of negative effects of the DHMO substance including some of the following:
 * Clear and odorless
 * It is a highly reactive substance
 * It contributes to global warming/climate change
 * It is one of the most predominant of the greenhouse gasses
 * It is the main component of acid rain
 * It is found in substances such as Sulfuric Acid, Nitroglycerie, and Ethyl Alcohol
 * Can cause death if inhaled in even very small amounts
 * In a gaseous form, it can cause severe burns

The hoax gained more widespread attention in the 1990's with the help of University of California, Davis students Eric Lechner, Lars Norpchen, Craig Jackson, and Matthew Kaufman. In 1997, a 14-year-old boy brought the greatest amount of attention to the issue when he circulated a popular petition to ban the substance on the grounds on the grounds of all of its dangerous effects.

Initially, the hoax was generated to call attention to a widespread lack of scientific literacy among normal people, as well as it was a way to illustrate how a carefully-worded analysis can create unwarranted fear in the media and in society.
