H2O Water is not an Element thus is not listed in the Periodic Table.
(aq) aqueous.
The chemical formula of heavy water is D2O.
Chemical formula (rather than 'symbol') of the pure compound: water is H2O. Mineral water is not a compound but a mixture of mainly water and some minerals dissolved in it. (The same is valid for tapwater)
Methane Hydrate is methane gas which has been frozen into water ice. Since it is a mixture of substances, and not an individual chemical, it does not have a chemical symbol. However, it can be represented by the chemical symbols of the compounds which make it up - Water, which is H2O, and Methane, which is CH4.
The same as water - H20
H2O IS THE CHEMICAL SYMBOL FOR WATER
H2O Water is not an Element thus is not listed in the Periodic Table.
Strictly, only elements have chemical "symbols". Compounds such as water have chemical formulas, and the one for water is H2O.
The chemical formula of water is H2O.
The chemical symbol for oxygen is "O." The chemical formula for water is "H2O."
Forms of Calcium is what makes hard water hard
The state symbol aq means it dissolves in water when it is written after a chemical compound in a chemical reaction.
(aq)
Ethanol C2H5OH Water H2O
The state symbol aq means it dissolves in water when it is written after a chemical compound in a chemical reaction.
