Everything tangible is at least one chemical; this includes water. Water is not an element, because it can be decomposed into oxygen and hydrogen by chemical means.
Pure water is a compound.
Only tin is a chemical element. Coal is not an element because it is impure.
The chemical formula of ammonia is NH3; the solution in water is basic - NH4OH. The molecule NH3 is polar. Ammonia is not an element but a chemical compound.
Silver is already ametallic chemical element. But so is mercury (chemical element), and it can supposedly be turned into gold, which is another chemical element.
A chemical element is homogeneous only if it is monoisotopic; but in practice this aspect is neglected. A chemical element is not a "change".
Water is a chemical compound not a chemical element.
Iron (Fe) is a chemical element, water is a chemical compound (H2O).
The chemical composition of water is H2O.
No it is a compound
No. Oxygen is a chemical element. Water is a chemical compound of hydrogen and oxygen.
The chemical formula of water is H2O (hydrogen and oxygen).
Water is not an element, it is a compound composed of oxygen and hydrogen. The chemical formula for it is H2O. That is 2 hydrogens and 1 oxygen atoms combined.
Water (H2O) is a chemical compound and iron (Fe) is a chemical element.
Pure water is a compound.
because the k is the reactivity of similar chemical
Ummm, the chemical element of water is H2o. :) Mabel Lautner ♥
