Water is different from hydrogen and oxygen in the same way that wood ash is different from wood and oxygen. Both water and wood ash are the products of combustion.
some physical differences are:
water is not flammable where as hydrogen is and oxygen aids combustion since it is an oxidizer
It is capable of dissolving a wide verity of substances into solution (is NaCl)
it is in liquid form at standard atmospheric pressure and temperature where as hydrogen and oxygen are both gases.
i think i mean that there are hold lot of element that why i pick this answer!
For example, at normal temperature and pressure both hydrogen and oxygen are gases.
Syrup is a mixture different sugars and water. So it is composed of the elements carbon, hydrogen, and oxygen.
Lead (Pb, #82 on the periodic chart) is an element in itself. Elements, which are pure substances, cannot be broken down into further chemicals. Therefore, there are no chemical elements that make up lead other than Pb, itself.
answer here... carbon,potassium,magnesium,water,hydrogen and calcium
Water contains the elements hydrogen and oxygen in a 2 to 1 ratio. The chemical formula for water is H2O.

If you have a set of 6 elements, you can make a total of 26 different subsets - including the empty set and the set itself.

Water. You can burn oxygen and you can burn hydrogen but you can't burn water.
Water is different from hydrogen and oxygen in the same way that wood ash is different from wood and oxygen. Both water and wood ash are the products of combustion.
here are some basics, fire and air, fire water , and water and water, you should learn the rest.
Iron is, itself, and element. It is not a compound of two elements.
Potassium is an element by itself.
Boron is an element in itself.
well hydrogen itself is not a compound, it is an element. But hydrogen is mixed with many other elements to make compounds such as water h2o. hope this helps
Sodium is an element all by itself.
