The oxidation number of Mn in manganese VII oxide is +7.
+3 for Fe, -1 for Cl
The molecular formula for Ferric Oxide is Fe2O3.
Fe has an oxidation number of+2 in ferrous salts+3 in ferric saltsAs Br has an oxidation number of -1 in bromide, only two salts of Fe with Br are possible:FeBr2 = ferrous bromideFeBr3 = ferric bromideand FeBr DOES NOT EXIST
Oxidation -- (Iron Rust) ferric hydroxide and ferric oxide formed by oxidation. Hydrated Ferric Oxide causing deterioration at low tempuratures to metals containing Iron. Any film or coating on metals due to oxidation. Two pieces of metal containing Iron can be fused together by Rust.

Ferric compounds , including ferric oxide, are dark brown, reddish brown or chocolate brown.
i think you answered your own question. common rust is iron in its most stable form under normal conditions with the formula Fe2(III)O3 (ferric oxide)
The oxidation number of NO, nitrogen oxide, is +3.
Use for decolourizing of Ferric and Ferrus oxide , green colour to colourless. But Selenium have many oxidation state and can change oxidation state when furnace condition change Reduction to Oxidation.
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
