Hydrogen is an element. Water is a compound composed of two atoms of hydrogen and one of oxygen.
hydrogen and oxygen are the two elements which make up water
two elements hydrogen and oxygen is used to make water i.e H2O . there are two molecules of hydrogen and one molecule of oxygen
Hydrogen and oxygen. What is probably meant is which two elements make dihydrogen oxide (water; H2O). The answer remains the same: hydrogen and oxygen.
A molecule of water, which has the formula H2O, is made up of the elements hydrogen and oxygen.
The two elements that make up most of the oceans are hydrogen and oxygen, forming water molecules.
Hydrogen and Oxygen.
Hydrogen and Oxygen make H2O
It's H2O which means two hydrogen molecules to one oxygenThe elements of Hydrogen and oxygen are chemically joined together to form water. Two atoms of hydrogen and one atom of oxygen are joined together chemically to form one molecule of water.
Water is made up of two hydrogen atoms and one oxygen atom. the formula for water is H2O. the two elements the make up water are hydrogen and oxygen. the two elements the make up water are hydrogen and oxygen.
Hydrogen and oxygen............. H2O
Two elements, two hydrogen atoms and one oxygen atom
Oxygen and hydrogen are the two ellements that make up water.
