The iron is said to have oxidized into rust. The chemical reaction is: 2 Fe + O 2 → Fe 2 O 3. The iron metal is oxidized to form the iron oxide known as rust. Electrochemical reactions are great examples of oxidation reactions.

WebThe oxidation states of the various transition elements are: V- +5 ; Cr- +6; Mn- +6. We know that heavier members stabilises higher oxidation state in case of transition elements. So, the given order of oxidising power is based on increasing stability of lower species to which … WebThe electronic conductivities of oxides are usually several orders of magnitude greater than their ionic conductivities. The rate of diffusion of ions through the oxide layer is a slow process, and hence the oxidation drastically slows down. The oxidation now has a logarithmic type of growth. how much sleep should a 9 year old get
