Molecules are composed of one or more atoms.
You have it backward in your question.
Carbon monoxide is a type of molecule. It contains 1 carbon atom and 1 oxygen atom
Five molecules of H2SO4 contains 20 atoms of Oxygen
The chemical energy is a notion applied to molecules.
By definition, an element is a single atom, not a molecule.
Sodium Chloride is a molecule. A molecule contains 2 or more atoms. Each molecule of Sodium Chloride contains 1 sodium atom and 1 chloride atom.
Elemental copper does not have molecules. Instead it has a "formula unit", which is a single atom.
None. A water molecules contains one oxygen atom and two hydrogen atoms. Oxygen only contains oxygen.
Waters is made of molecules. Each of those molecules contains 3 atoms.
No, a H2O molecule, contains 2 hydrogen atoms and one oxygen atom - not the other way around as in the question.
It is true. A compound contains two or more different type of atoms.
The nucleus contains the mass.
Each molecule of copper(II) sulfate pentahydrate contains one copper atom, one sulfur atom, four oxygen atoms, and five water molecules. So, one molecule of copper(II) sulfate pentahydrate contains a total of 11 atoms.
