Therefore, we chose those colors to represent SAAC. However, each type of cancer has its own color, and these are listed below:
Reaction of iron with the halogens. Iron reacts with excess of the halogens F2, Cl2, and Br2, to form ferric, that is, Fe(III), halides. This reaction is not very successful for iodine because of thermodynamic problems. The iron(III) is too oxidizing and the iodide is too reducing.
Magnesium is more reactive than iron. So Magnesium loses electrons in preference to iron. Magnesium reacts with the oxygen in the air to form Magnesium Oxide, and the iron remains protected, because it has magnesium attached to it. Magnesium is oxidised as it dissolves. Iron ions are reduced to iron atoms. The iron ions take the electrons given out by magnesium, and form iron metal.
