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 (10[1])sodium hydroxide and is named for Murray Raney. (10[1])This element is (-5[1])produced by dissolving a precursor in cryolite and electrolyzing the (10[1])molten salt (10[1])bath. (10[2])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 (10[1])from its oxide, which is isolated in the (-5[1])Bayer process for refining bauxite (“BOX-ite”). For 10 points, name this ultralight metal used to make soda cans and foil. ■END■ (10[2])
