^Back to Main info PageWater is, in fact, a chemical. Its chemical formula is H2O (or, much less commonly, HOH), which is what this website is called after. H2O is also one that the most renowned chemical formulas. As soon as properly written, the "2" after the H is written in subscript (as you deserve to see in the banner above), however due to formatting restrictions it will merely be composed as "H2O" top top this website.What does H2O mean? each water molecule is make of 2 hydrogen atoms and also one oxygen atom, for this reason there space two "H" atoms and one "O". The atoms space joined through covalent bonding, definition that castle share electrons (as protest to ionic bonding, in which atoms completely transfer electrons). On the ideal is an image of water"s molecule structure.Water is the most abundant molecule on Earth. Around 70% that the Earth"s surface is water. Water is also the only substance on earth which naturally occurs in a solid, liquid and also gas form.The Celsius temperature scale is based upon waters" freezing suggest (0 degrees) and boiling suggest (100 degrees). Unlike many substances, water"s solid native is less dense than the liquid form - this is why ice cubes will float in her drinks. Water is additionally capable of absorbing a lot of heat prior to its temperature increases; hence it is used in things such as a radiator coolant in cars.Water has actually a high surface ar tension. This is why part bugs prefer water striders (of the Gerridae family) have the right to walk top top water - since they weigh less than the surface stress and anxiety of the water. Because of the form of a water molecule, molecule stick and clump together to form this high tension (the 2 lighter hydrogen atoms in the image on the ideal could connect to the oxygen atom of one more water molecule, and so forth). That"s why water comes together in the kind of autumn - if that wasn"t for heaviness water would attach together in a spherical shape.Please visit the links page because that a list of websites where you can learn more information around the chemistry of water, and also many various other things.
