MgCl2 – magnesium chloride. The oxidation state of magnesium is +2, the oxidation state of chlorine is -1.

CaO – calcium oxide. The oxidation state of calcium is +2, the oxidation state of oxygen is -2.

HF – oxidation state of hydrogen +1, oxidation state of fluorine -1.

SO3 – sulfur oxide. The oxidation state of sulfur is +6, the oxidation state of oxygen is -2.

KOH – potassium hydroxide. The oxidation state of potassium is +1, the oxidation state of hydrogen is +1, and the oxidation state of oxygen is -2.

KMnO4 – potassium permanganate. The oxidation state of potassium is +1, the oxidation state of manganese is +7, the oxidation state of oxygen is -2.

H2SO4 – sulfuric acid. The oxidation state of hydrogen is +1, the oxidation state of sulfur is +6, and the oxidation state of oxygen is -2.
