1) Of the metals Ni, Au, Hg, and Ag, which will give up its electrons to copper (Cu) in a redox reaction?
A. Hg
B. Ni
C. Au
D. Ag

2) Of the metals Li, Al, Na, and K, which will not spontaneously donate electrons to magnesium (Mg)?
A. Al
B. Li
C. Na
D. K

Respuesta :

The more active the metal, the more easily it gives up its electron(s). Thus, for number 1, nickel is the only metal of the options that is more active than copper and is the only metal that would give up electrons for copper. For number 2, aluminum is the only metal that is less active than magnesium and is the only metal that would not donate electrons to magnesium.
