Packet 3: Tossup 16

Octahedra of this element’s oxyanion are linked to silicate tetrahedra in kaolinite. Inclusions of calcium and this element (15[1])are used to define the age of the solar system. Oxides of this non-transition metal element (15[1]-5[1])are passed through a flame-fusion process (-5[1])named for Verneuil. Oxides of silicon and this element make up adsorbent, microporous catalysts known as (15[1])zeolites. (15[3])All (*) feldspars (10[4])contain (10[1]-5[1])silicon, (10[3]-5[1])oxygen, (10[1])and this element. (10[1]-5[3])This element is the most (10[1])abundant metal in Earth’s (10[1]-5[3])crust. (10[6]-5[3])The Bayer process (10[1]-5[2])refines (-5[1])the oxide (-5[1])of this element (10[1])from its ore, (10[1])bauxite. (10[3]-5[1])For 10 (10[2])points, (10[1])name (10[1])this element usually found in soda cans and foil. (10[2])■END■ (10[8]0[1])
