1) Statement (A) Mg can reduce $Al_{2}O_{3}$ above $1350^{0} C$ Statement (B) Al can reduce MgO below $1350^{0} C$ The correct answer is A) Both (A) and (B) are wrong B) (A) is correct, but (B) is wrong C) (A) is wrong , but (B) `is correct D) Both (A) and (B)are correct Answer: Option AExplanation:Mg can reduce $Al_{2}O_{3}$ below 1350° C according to the Ellingham diagram. On the other hand, Al can reduce MgO above $1350^{0} C$. Thus, both statements (A) and (B) are incorrect.
