Tossup

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