The process of rusting is called oxidation reaction, in which there is a gain of oxygen with the loss of electrons. When iron rusts iron molecules react with oxygen molecules to make a compound called iron oxide. It is widely used as a catalyst to manufacture in medicine, dyes, and various other chemicals. For Example, when the iron is exposed to air and moisture, rust formation takes place. However, if energy is provided to the mixture in the form of heat, the zinc will chemically react with the sulfur to form the compound zinc sulfide (ZnS). Hans C. B.

The melted ice cube may be refrozen, so melting is a reversible physical change. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently. Rust is the result of corroding steel after the iron (Fe) particles have been exposed to oxygen and moisture (e.g., humidity, vapor, immersion). How can you tell if a chemical reaction is taking place? Sam Kashyap.
