Will ever h2o be not water?

Sure, below 32 degrees it's ice.  Above 212 degrees it's steam.

No. It is a chemical compound. All rain water is a compound of two elements hydrogen and oxygen. The chemical formula for water is h2o - meaning two hydrogen atoms and one oxygen. Usually when rain becomes acid it has sulfur dioxide (another compound formed of sulfur and oxygen) and nitrogen oxide (yet another compound formed from the combination of the elements nitrogen and oxygen as well). These chemicals combine with the water to form sulphuric acid and nitric acid.

That is definitely not correct!!\n\nFor example water (H20) is very very different from the two gases that make it namely hydrogen (H2) and oxygen (O2)

H2O. Lots of it. Stay in the shade.

Didn't you just ask this?\n\nThe H2O molecule can be broken into component atoms (H and O) under the right conditions, yes.  Smaller than that and you'll need a heat source like the Sun to create a plasma, which breaks the atomic nucleii into protons, neutrons, and smaller particles.\n\nOtherwise, H2O can form H+ and OH- ions, or H2 and O2 gas.

water as in H2O? just ok...\nyeah covered with it... \nas long as the planet is not made up entirely of water.... that wold be like a big floating water vapor....\nhaha

A very good question.\n\nAlmost all common chemical will contract upon freezing, but not water. \nThe special hydrogen bonding that forces the water molecule to be very close to eacher other in liquid phase.\n\nThe molecule of HOH is not straight, but in a V shape. About 105 degree.\nIn liquid phase the V shape can over lap each other. Go look up the water structure at\nhttp://www.chem1.com/acad/sci/aboutwater.html\n\nDuring freezing, the water molecule are force to line up, and the V shape molecule are line up side by side and no longer over lap.  This takes more room. So it expands.\n\nGo look up the ice molecule structure at http://www.uwgb.edu/dutchs/PETROLGY/Ice%20Structure.HTM\n\nIts not easy to see the true structure, but these will at least gives you a picture.\n\nKeep asking questions, enjoy.

It would make water (H2O).

Absolute zero.  There are ways to keep water from freezing using pressure, motion, impurities, and so forth.

yes u r correct , u need vapour pressure of H2O. From vapour pressure calculate vapour density of H2O\n  Now, u can easily calculate molecular mass of the unknown as it  is twice the vapour density

Water is not wet, it makes things wet!

Pure water, H2O is a terrible conductor of electricity, however, water that has hard water deposits and other impurities in it is a great conductor

Di-hydrogen oxide would be the chemical name of water. H2O is the chemical formula. The are many ways a person could draw a physical model of it. Now there are other chemicals and ions that only contain hydrogen and oxygen. There is Hydrogen peroxide as an example of a chemical. There are hydroxide ions HO- and oxonium ions H3O+. There is a limit to how many chemicals can be derived by both Hydrogen and oxygen because Hydrogen can only bond to one atom at a time, and Oxygen can only bond to two atoms at a time. Although that would in theory allow an oxygen chain that could have a hydrogen atom on each end with the exception of hydrogen peroxide H2O2, this does not occur. Species with only oxygen. An oxygen atom O it seldom ever found in nature for electronic reasons. An oxygen diatomic molecule O2 is the most abundant form of pure oxygen in the atmosphere. Ozone O3 is not particularly stable it is usually made by free radical chain reaction, but then tries to react with whatever it can. H atomic Hydrogen seldom ever found in nature. Diatomic hydrogen molecule H2 is the most abundant species in the universe, but somewhat rare on earth. Hydrogen H+ ion can exist, but in water it is the short hand for writing H3O+ which I referred to earlier.
