A student investigated the displacement reactions of different metals by adding them to nickel(II) sulfate solution and measuring the temperature rise.
Their results are shown in the table below.
| Metal added to nickel(II) sulfate solution | Temperature rise / °C |
|---|---|
| magnesium | 7.2 |
| copper | 0.0 |
| zinc | 3.5 |
Explain the order of reactivity of the metals magnesium, copper, and zinc using the results.
