aluminum - 2025 ACF Fall

Tossup

A powder of this element reduces iron oxide in exothermic welding due to its (10[1])high (10[1])affinity (10[2])for oxygen. (10[7]-5[2])A catalyst (10[1])of this (-5[1])element alloyed with nickel is activated (10[2]-5[1])with (10[1])sodium hydroxide (10[2])and is named (10[1])for Murray Raney. (10[6]-5[1])This element (10[1])is (10[1]-5[1])produced (-5[2])by dissolving a precursor (10[1]-5[3])in cryolite (10[1])and (10[1])electrolyzing (10[2]-5[1])the (10[1])molten (10[1])salt (10[2])bath. (10[5]-5[1])This element is the third most abundant (10[1])in the Earth’s (10[1])crust (10[2]-5[1])after oxygen (10[2]-5[1])and silicon. (10[1]-5[1])This element (10[1]-5[1])is produced in the (10[2]-5[1])Hall–Héroult (10[4])(“hall-ay-ROO”) process (10[4])from (10[1])its (10[2])oxide, (10[1]-5[1])which is isolated (10[1]-5[1])in the (-5[1])Bayer (0[1]-5[1])process (-5[2])for refining (10[1])bauxite (10[4]-5[2])(“BOX-ite”). For (10[1])10 (-5[1])points, (10[3]-5[1])name this ultralight metal used to make (10[3])soda cans (10[1])and foil. (10[2])■END■ (10[22]0[3])
