Water is a compound and Hydrogen and Oxygen are elements. Elements are substances whose atoms all contain exactly the same number of protons. Water has a melting point over a hundred degrees above the boiling point of either Hydrogen or Oxygen. This is why water is mostly in its liquid form on earth's surface and Hydrogen and Oxygen are always found as gasses. Water is also one of the very few substances whose solid is less dense than its liquid.
This is why ice floats.

What two elements is water made up of?
Oxygen and hydrogen are the two ellements that make up water.
Is water an oxide or a hydride?
Water is the oxyde of hydrogen - H2O.Added:I agree, though if 'seen' from the oxygen side it could be named as an hydride of Oxygen: OH2, (compare PH3, phosphorhydride) but it is rather unusual.
Is pure water a mixture a compound or a element?
No. It is a compound made of the elements oxygen and hydrogen: H2O.
Does water contain nitrogen carbon oxygen and hydrogen?
water is made of two hydrogen and one oxygen. (H2O)
Can you create hydrogen and oxygen without using water?
We can't create hydrogen and oxygen because they are natural, water is a mixture of both. Hydrogen and oxygen are elements and can't be made.
Compare and contrast the relationships of oxygen and water to fire?
- Oxygen support combustion; combustion is a reaction with oxygen, an oxydation.- Hydrogen is burned with oxygen.- Water can turn off some fires.
What do you get when you electrolyse water?
Hydrogen and oxygen are the products of electroysis of water .
What elements are found in both carbohydrates and water?
Water contains hydrogen and oxygen. Sugar contains carbon, hydrogen and oxygen.
When hydrogen and oxygen conforms to water what would water be considered and what would hydrogen and oxygen be considered?
Hydrogen and oxygen are the reactants and water is the product.
What two elements make up the chemical structure of water?
hydrogen and oxygen are the two elements which make up water
When hydrogen and oxygen combine to form water oxygen is?
When hydrogen and oxygen combine to form water, water is a product of the reaction.
How many elements compose of pure water?
Water is composed from hydrogen and oxygen.
Does hydrogen and oxygen makes water?
Yes, water is comprised of Hydrogen and Oxygen, H2O
Does water combine with hydrogen to make oxygen?
No. Hydrogen combines with oxygen to make water.
Can you get water from hydrogen?
You can get water from hydrogen if you combine the hydrogen with oxygen atoms.
Describe two ways to compare the densities of unknown substances?
You can always compare the densities by the formula d=m/v, where m is the mass and v is the volume . However; a simpler technique is to put the objects in some water . The densities can be compared by how much water each of them will displace.
Two atoms of Hydrogen combine with one atom of Oxygen to form water. This combination is?
hydrogen + oxygen = HO, hydroxide: hydrogen + oxygen + oxygen = H20, water
