Manganese, nickel and silver are metals. Samples of powdered manganese, nickel and silver were put into separate test-tubes of dilute hydrochloric acid. The observations are shown. What is the order of reactivity of the metals, from most reactive to least reactive?
- Amanganese → nickel → silver
- Bmanganese → silver → nickel
- Csilver → manganese → nickel
- Dsilver → nickel → manganese
