Tossup
A powder of this element reduces iron oxide in exothermic welding due to its high affinity for oxygen. A catalyst of this element alloyed with nickel is activated with sodium hydroxide and is named for Murray Raney. This element is produced by dissolving a precursor in cryolite 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 (“BOX-ite”). For 10 points, name this ultralight metal used to make soda cans and foil. ■END■
