Round 7: Tossup 15

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