The reactivity series for some metals, with two gaps labelled X and Y, is shown. most reactive K Na Ca Mg X Zn Y Pb (H) Cu Ag least reactive Which row correctly identifies metals X and Y and the method of extraction of Y from its ore?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

Ametal X: Al, metal Y: Fe, method of extraction of Y: electrolysis

Bmetal X: Al, metal Y: Fe, method of extraction of Y: reduction with carbon

Cmetal X: Fe, metal Y: Al, method of extraction of Y: electrolysis

Dmetal X: Fe, metal Y: Al, method of extraction of Y: reduction with carbon

✓ Correct answer

B: metal X: Al, metal Y: Fe, method of extraction of Y: reduction with carbon
