Answer: What type of chemical reaction is rusting of iron?
Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3. Water is necessary for the oxidation reaction to occur and to facilitate transport of the electrons.
When a radioactive isotope releases an alpha particle, the atomic number of the atom is decreased by four.
