None. A water molecules contains one oxygen atom and two hydrogen atoms. Oxygen only contains oxygen.
No, an element is a substance that contains only one type of molecule.
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
Water gas is commonly referred to as steam. Steam is made of the same molecules as water. Water gas contains two hydrogens bonded to one oxygen.
Water contains two kinds of atoms: 1 oxygen atom & 2 hydrogen atoms.
None. A water molecules contains one oxygen atom and two hydrogen atoms. Oxygen only contains oxygen.
It contains one molecule of oxygen and two molecules of hydrogen.
One mole of any molecule contains avogadro number of molecules. and that is equal to 6.023 X 1023
No, an element is a substance that contains only one type of molecule.
compound
Yes, there is air in ice, only small traces of it, as well as the fact that it contains water, which has two molecules of Hydrogen and one molecule of Oxygen, therefore being air whilst in a liquid form. And as you know, ice is just a frozen version of water, therefore ice contains water.
Methane is one. Molecules that contain only carbon and hydrogen are called hydrocarbons.
Hydrogen
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
Molecules are composed of one or more atoms. You have it backward in your question.
Water gas is commonly referred to as steam. Steam is made of the same molecules as water. Water gas contains two hydrogens bonded to one oxygen.
