The results of experiments involving four metals, W, X, Y and Z, and their ions are shown. Y(s) + Z⁺(aq) → Y⁺(aq) + Z(s) W(s) + X⁺(aq) → no reaction Z(s) + X⁺(aq) → Z⁺(aq) + X(s) What is the order of reactivity of the four metals, most reactive to least reactive?

AW → X → Y → Z

BX → W → Z → Y

CY → Z → X → W

DZ → Y → W → X

✓ Correct answer

C: Y → Z → X → W
