The correct formula for elemental oxygen is O2, indicating that oxygen exists as a diatomic molecule with two oxygen atoms bonded together.
The chemical symbol for the element oxygen is O. The chemical formula for oxygen in its elemental form, oxygen gas, is O2.
The correct formula for a compound with 3 oxygen atoms and 1 sulfur atom is SO₃, which is sulfur trioxide.
A sulfur molecule with the elemental formula Sg does not exist. It is likely a typographical error. The atomic number of sulfur is 16, so a sulfur molecule would typically contain 8 atoms (S8) in its elemental form.
Chlorine exists as a diatomic gas in its elemental form, represented by the chemical formula Cl2.
The correct chemical formula for iron oxide is Fe2O3. This formula represents a compound composed of two atoms of iron (Fe) and three atoms of oxygen (O).
The chemical formula for oxygen is O2, which means that it is composed of two oxygen atoms bonded together.
