(B) The Goldschmidt reaction,also known as the thermite process,involves the reduction of metal oxides (such as $Fe_2O_3$ or $Cr_2O_3$) using metallic aluminum as a reducing agent. The reaction is highly exothermic and is represented by the general equation: $M_xO_y + yAl ightarrow xM + y/2 Al_2O_3 + 	ext{Heat}$. Because aluminum has a very high affinity for oxygen,it effectively reduces these oxides to their respective metals.
