ZnO.
Zinc white is a name for zinc oxide - ZnO, used as dye.
ZnO is the chemical formula of the zinc oxide.
The chemical formula of the combination of Zn and O is called zinc oxide and has the chemical formula ZnO. Zn2O2 is not a compound.
The chemical formula for cadmium sulfide is CdS.
Zinc doesn't react with water at room temperature.
The chemical formula ZnN don't exist; the zinc nitride has the chemical formula Zn3N2.
The chemical formula (not symbol) of zinc oxide is ZnO.
This is zinc oxide doped with sulfur.
The formula is ZnO. Zn has an ion charge of 2+ and 0 has an ion charge of 2-. Therefore it cancels each other out only leaving Zn0.
Since zinc oxide is an ionic lattice when solid, it does not have a structural formula. Its empirical formula is ZnO.
The chemical formula of zinc carbonate is ZnCO3.
ZnCl2. Zinc has a positive 2 charge and chloride has a negative 1 charge. You balance the charges of zinc and chloride and you get ZnCl2
