There are 10 hydrogen atoms in five H2 molecules.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
hydrogen oxide is water or H2O and has two hydrogens
H2O. Two atoms of hydrogen and one atom of oxygen.
The chemical formula for water is H2O. The subscripted "2" indicates that there are two atoms of hydrogen in one water molecule. No subcripted number means there is just one atom in the molecule, meaning there are two hydrogen atoms and one oxygen atom.
Three: two hydrogen atoms and one oxygen atom. Hence the formula, H2O.
There are two hydrogen atoms in one molecule of water (H2O).
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
H2OCount two atoms hydrogen in one molecule of water.
there are 2 atoms of hydrogen in water
The chemical formula of water is H2O; water contain two hydrogen atoms.
A water molecule (H2O) contain two hydrogen atoms.
the water molecule is H2O so it has 2 atoms of hydrogen in it. (plus an atom of oxygen)
There are three atoms in a molecule of water. One oxygen atom and 2 hydrogen atoms. The simplified form for the molecule of water is H2O which is a coded form for the 2 hydrogen and 1 oxygen atoms that make up the molecule.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
hydrogen oxide is water or H2O and has two hydrogens
Hydrogen oxide (also known as water) contains two hydrogen atoms and one oxygen atom in each molecule.
There are 2 hydrogen atoms present in each water molecule. This can be seen from the formula for water H2O -- this tells us there are 2 atoms of hydrogen combined with 1 atom of oxygen
