Now that we are familiar with the structures of single chain macromolecules, we are in a position to look at some of the interactions of macromolecules with other macromolecules and with smaller molecules.
Corrosion on exposed metal. Corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.
Corrosion is a natural process. Metals donât like being metals, they prefer remaining as ores. In the process of converting ores into metals, energy is added. in the form of heat, this places the metal into a high-energy. state. It is this energy that is given off from the metal, as the metal is. returning to an ore, lower-energy state, is what we call. corrosion. Steel - Rust to Rust.
