A student heats four metals, W, X, Y and Z, with the oxides of some of the other metals.
| Mixture heated | Reaction? |
|---|---|
| W and the oxide of X | yes |
| X and the oxide of Z | no |
| Y and the oxide of W | yes |
| Z and the oxide of W | no |
What is the order of reactivity of the metals, from most reactive to least reactive?
Y, W, Z, X
W, Y, X, Z
Y, W, X, Z
X, Z, W, Y
