Aluminium chloride is manufactured on a large scale by the exothermic reaction of aluminium metal with chlorine or hydrogen chloride at temperatures between 650 to 750 Â°C (1,202 to 1,382 Â°F).n the melt, aluminium trichloride exists as the dimer Al 2 Cl 6, with tetracoordinate aluminium. This change in structure is related to the lower density of the liquid phase (1.78 g/cm 3) vs solid aluminium trichloride (2.48 g/cm 3).

Basically, cephalization is the process which enables organisms to have a brain. At an intermediate level of this process, organisms may also possess ganglia, which refer to groups of nerve cells or mini control centers that are scattered throughout their bodies.he neurons become concentrated in the head region and allows the brain of the organism to be situated in one place. Cephalization is beneficial because it allows a complex brain to be developed.
