A) Fe and\[Al\]
B) ferric oxide and aluminium powder
C) barium peroxide and magnesium powder
D) \[Cu\]and\[Al\]
Correct Answer: B
Solution :
Thermite (used in aluminothermy or Gold schmidt aluminothermic process) is a mixture of ferric oxide and aluminium powder. Reduction of\[F{{e}_{2}}{{O}_{3}}\]takes place and large amount of heat is evolved in this reaction. \[F{{e}_{2}}{{O}_{3}}+2Al\xrightarrow[{}]{{}}A{{l}_{2}}{{O}_{3}}+2Fe+heat\]
