Three different metal ribbon samples are added to separate beakers containing dilute sulfuric acid of the same concentration.
| Metal | Observation |
|---|---|
| Magnesium | Vigorous effervescence, the ribbon quickly disappears, and a significant temperature rise is recorded |
| Silver | No visible reaction occurs and the temperature remains constant |
| Iron | Gentle, continuous bubbling is observed |
Place these three metals in order of reactivity from most reactive to least reactive.
Most reactive: ______
Least reactive: ______
