In a Series of Chemical Test Reactions, the Following Observations

Multiple Choice

In a series of chemical test reactions, the following observations were made when several metallic element samples were treated with 3.00 M hydrochloric acid solution. Zn: metal dissolves, hydrogen gas is emitted. Cu: no reaction. Ag: no reaction. Mg: metal dissolves, hydrogen gas is emitted. Mn: metal dissolves, hydrogen gas is emitted. Which statement below is true?

A) Mg, Mn, Zn are more reactive than Ag, Cu; but less reactive than H₂.
B) Mg, Mn, Zn are less reactive than Ag, Cu; but more reactive than H₂.
C) Mg, Mn, Zn are more reactive than Ag, Cu, and H₂.
D) Mg, Mn, Zn are less reactive than Ag, Cu, and H₂.
E) These observations are insufficient to form any judgment about relative reactivity of any of the elements tested.
