Three metals, X, Y and Z, were each added to the same volume and concentration of dilute hydrochloric acid. The pieces of metal had the same mass and surface area, and the reactions were carried out at the same temperature. The volume of hydrogen produced in the first 30 seconds was recorded.
| Metal | Volume of hydrogen produced in 30 seconds (cm³) |
|---|---|
| X | 18 |
| Y | 7 |
| Z | 42 |
State the order of reactivity of the three metals, starting with the most reactive.
Using your order, explain whether metal Y would displace metal X from a solution of X sulfate.
