Rusting: Rusting is an oxidation reaction. The iron REACTS with WATER and oxygen to form hydrated iron(III) oxide, which we see as rust. Here is the word equation for the reaction: iron + water + oxygen → hydrated iron(III) oxide.Crystallization: Crystallization is a method for transforming a solution into a solid, where a supersaturated solution nucleates the solute by a chemical equilibrium controlled process. UNIFORM particles with well-defined morphology are formed, and these readily re-dissolve. great examples of the crystallization of water. Another interesting example is the crystallization of honey. When bees regurgitate honey into the HONEYCOMB, it is a liquidGalvanisation:Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel SECTIONS are submerged in a bath of molten zinc.Galvanizing protects the underlying iron or steel in the following main ways: The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron. The zinc protects iron by corroding first. Explanation:I hope it will help u ✌️MARK me brainliest
