One of several iron oxides, it is a black-colored powder that’s sometimes confused with rust, the latter of which consists of hydrated iron oxide . Rusting is a chemical response of iron within the presence of oxygen. This response is relatively gradual and produces a skinny coating of secure iron oxide Fe2O3, which is rust, but is a fairly benign form of rust. This produces hydrated iron oxide, or RUST . You do not use the prefix di for the nitrate since that is an ionic compound, and it may possibly solely be 2 as nitrate has a -1 charge and Mg has a +2 charge.
