A student adds pieces of four metals, W, X, Y and Z, to solutions of each other's nitrates. A tick shows that the metal displaced the other metal from its salt solution.
| Metal added | W nitrate | X nitrate | Y nitrate | Z nitrate |
|---|---|---|---|---|
| W | not tested | no reaction | no reaction | tick |
| X | tick | not tested | tick | tick |
| Y | tick | no reaction | not tested | tick |
| Z | no reaction | no reaction | no reaction | not tested |
What is the order of reactivity of the metals, most reactive first?
X, Y, W, Z
Z, W, Y, X
X, W, Y, Z
Y, X, W, Z
