Allspice is the only spice that is grown exclusively in the Western Hemisphere. The evergreen tree that produces the allspice berries is indigenous to the rainforests of South and Central America where it grows wild.Unfortunately the wild trees were cut down to harvest the berries and few remain today.llspice is the only spice that is grown exclusively in the Western Hemisphere.

Very pure gallium metal has a silvery color and its solid metal fractures conchoidally like glass. Gallium metal expands by 3.1% when it solidifies, and therefore storage in either glass or metal containers is avoided, due to the possibility of container rupture with freezing.
Gallium trichloride is the chemical compound with the formula GaCl 3. Solid gallium trichloride exists as a dimer with the formula Ga 2 Cl 6. It is colourless and soluble in virtually all solvents, even alkanes, which is truly unusual for a metal halide. It is the main precursor to most derivatives of gallium and a reagent in organic synthesis. As a Lewis acid, GaCl 3 is milder than aluminium trichloride. Gallium(III) is easier to reduce than Al(III), so the chemistry of reduced gallium compounds is more extensive than for aluminium. Ga 2 Cl 4 is known whereas the corresponding Al 2 Cl 4 is not.
