Round 7: Tossup 15

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