Answer
(A)- (IV), (B)- (III), (C)- (I), (D)- (II)
Explanation
Solution
(A) Mn2+ corresponds to the highest oxidation states.(B) Spin-only magnetic moment follows the formula μs = √n(n + 2) BM. (C) MnO2 is found in pyrolusite ore. (D) Misch metal is an alloy of 4f metal with iron, sulfur, carbon, aluminum, and calcium.
