It is more likely that water broke down over millions of years and created our current friendly air.
Water molecule contain hydrogen and oxygen; the chemical formula is H2O.
Hydrogen and oxygen combined with a catalyst create water.
Water is H2O, two hydrogen atoms and one oxygen atoms.
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
H2o
Water? Well, water is H20.
Water, H2O, is a molecule of hydrogen and oxygen. It is considered a compound. That said, yes, oxygen and hydrogen combine to make a compound that is represented by the molecule H2O.
Water.
In Greek, Hydro means "water", and Gen means "create." So hydrogen means "water-making." And it takes 2 hydrogen atoms combined with an Oxygen atom to create water.
Two elements are combined together in water: hydrogen and oxygen. Water has a chemical formula of H2O, which means each water molecule contains two hydrogen atoms and one oxygen atom.
people create water by adding or mix Hydrogen with Oxygen to create water
Hydrogen is the explosive gas that, when combined with oxygen in a process called electrolysis, can produce water. In this reaction, two molecules of hydrogen combine with one molecule of oxygen to form two molecules of water.
When hydrogen and oxygen combine, they undergo a chemical reaction that forms water. This reaction involves the bonding of hydrogen and oxygen atoms to create water molecules, with two hydrogen atoms bonding with one oxygen atom to form a water molecule (H2O).
