H2O (g) as it is water but just a gas Ice would be similar but just with a change of state symbol, Correction - water vapour/steam has the chemical formula of 7H20, and it water has never been ...
In chemistry, a symbol is an abbreviation for a chemical element.Symbols for chemical elements normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.. Earlier symbols for chemical elements stem from classical Latin and Greek vocabulary. For some elements, this is because the material was known in ancient times, while for others, the ...
Nov 04, 2008· The gaseous, liquid and solid forms of any material have the same chemical formula no matter what. Water, ice and gaseous water (steam, fog, etc.) is always H20.
Water, substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful of compounds and has the important ability to dissolve many other substances, which was essential to the development of life.
The Greeks proposed the existence of five basic elements. Of these, four were the physical elements—fire, air, water, and earth—of which the entire world is composed. Alchemists eventually associated four triangular symbols to represent these elements.
Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour.
The chemical formula for water vapor is H 2 O. Water is a unique compound because it has the ability to exist on the earth's surface in all three forms: liquid, solid (ice), and gas (water vapor). Water vapor is the gas phase of water, and is invisible. The measure of the amount of water vapor suspended in the air is what is known as humidity.
