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.
Alkali metals react violently with water, halogens, and acids. The reactions release surprising amounts of heat and light. Alkali metals react with oxygen to form oxides, which have a duller appearance and lower reactivity. The oxides are much less reactive than the pure metals.
