Reactivity of metals：練習問題

Which of the following metals is the most reactive when added to water at room temperature?

A student places a piece of zinc into a solution of copper(II) sulfate. Which statement correctly describes the outcome based on the reactivity of metals?

(HT only) In a displacement reaction between magnesium and copper(II) chloride, which species is acting as the reducing agent and why?

A student adds a piece of magnesium ribbon to a beaker containing hydrochloric acid. What are the products formed in this reaction?

Based on their position in the reactivity series, which metal will displace iron from a solution of iron(II) sulfate?

A student adds an unknown metal to water and observes a very rapid reaction with fizzing. Suggest the position of this metal in the reactivity series relative to calcium and copper.

A displacement reaction occurs when zinc is added to a solution of copper(II) sulfate. Write the ionic equation for this reaction and identify which species is being oxidised.

Identify which species is oxidised and which is reduced in the following displacement reaction:
\( Mg(s) + Cu^{2+}(aq) \rightarrow Mg^{2+}(aq) + Cu(s) \)
