Dihydrogen Monoxide Trivia Quiz

Answer: All of these

Well, now you know what it's about: water, the common name for H2O.
Hydroxyl acid, hydrogen oxide, dihydrogen monoxide, hydric acid and others are all names sometimes used for water that are scientifically correct but are not officially sanctioned.

Answer: Hydrosphere

The hydrosphere is the whole amount of water present on Earth; it includes air, surface and underground water, in its liquid, vapor, or ice forms.

Answer: 0.023%

The hydrosphere masses about 1.4 X 10^18 tonnes out of a total Earth mass of 5.97219 X 10^24 tonnes.

Answer: The Arctic Ocean

The oceans cover 71% of the Earth's surface divided between the five oceans.
The Pacific Ocean has an area of 155,557,000 sq km, the Atlantic Ocean 76,762,000 sq km, the Indian Ocean 68,566,000 sq km, the Southern or Antarctic Ocean 20,327,000 sq km and the Arctic Ocean 14,056,000 sq km.

Answer: Antarctica

Freshwater represents about 2.5% of the world's water. Around 70% of this freshwater is ice (polar regions, mountain glaciers, and seasonal snow). Around 30% is groundwater (aquifers and soil humidity). Surface freshwater (rivers, lakes, swamps) is less than 1% of all freshwater and this is the most important and easily available water to us.

About 65% of the world's fresh water is locked in Antarctica's ice.
Lake Baikal is the deepest lake in the world (1,642 m - 5,387 ft) and the biggest in volume of water. About 20% of the world's surface freshwater is there.

The Amazon River is the second river in the world in length but is the greatest in volume and accounts for approximately one-fifth of the world's total river flow into the oceans.

Answer: Yes

The Earth is unique in that it is the only planet in the solar system where there are surface temperatures that permit a water cycle, with liquid surface water.

There is evidence that these conditions also existed in Mars and speculation about the same in Venus.

Some planetary moons, most notably Europa, may have liquid water, but not on the surface.

Answer: Inside the cells

About 2/3 of our body's water is inside our cells (intracellular fluid). The remaining water (extracellular fluid) is divided between blood plasma (1/5 of extracellular fluid) and the interstitial fluid (4/5). The urinary bladder has no fixed amount of water.

Answer: 3 to 5 days

Our life expectancy without water is very low, from a few hours in extreme circumstances to a record 17 days in an earthquake survivor.

Answer: Water

Hydrogen can be used as a clean, alternative energy source, because its combustion produces water.

Hydrogen peroxide (H2O2) is the simplest peroxide and is a strong oxidizer.
Heavy water or deuterium oxide is a form of water that contains the hydrogen isotope deuterium (hydrogen atom with a proton and a neutron) which makes this water about 11% heavier than normal water.

Helium can be obtained by the fusion of two deuterium atoms.

Answer: All of these are absurdly correct

The dihydrogen monoxide hoax involves calling water by an unfamiliar name and then exposing people's illiteracy by raising a cry to pass laws preventing/controlling the use of this "substance". On the Coalition to Ban Dihydrogen Monoxide site you can find many more examples of the "dangers" of water. If you want to have some fun, visit for more information on the dihydrogen monoxide hoax.
