What is so special about water?
Its most spectacular property is that ice floats in water. Water is also the best all-around solvent. More solid substances dissolve in water than in any other liquid. Water consists of molecules with the composition H2O (two small atoms of hydrogen and one larger atom of oxygen).
What is water known as?
Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.
What is H2O full name?
H2O is the molecular formula of water, also called Dihydrogen monoxide. H2O symbolises two hydrogen atoms and one oxygen atom.
