Question

Rank Sn, Cu, H, Zn, Cu, Fe, Mg, Ag, Pb, and Na in the order of activity.

a) Ag > Pb > Sn > Cu > Fe > H > Zn > Mg > Na
b) Na > Mg > Zn > H > Fe > Cu > Sn > Pb > Ag
c) Ag > Pb > Sn > Cu > H > Fe > Zn > Mg > Na
d) Na > Mg > Zn > Fe > Cu > Sn > Pb > Ag > H

Answer 1

The correct ranking of the given elements in order of activity is: Na > Mg > Zn > Fe > Cu > Sn > Pb > Ag > H.

Step-by-step explanation:

The correct ranking of the given elements in order of activity is: Na > Mg > Zn > Fe > Cu > Sn > Pb > Ag > H.

This ranking is based on the activity series, which lists metals and hydrogen according to their tendency to be oxidized in single-displacement reactions. Metals higher up in the series are more active and can replace metals lower in the series in a reaction. Hydrogen is included in the series as well.

For example, sodium (Na) is more active than magnesium (Mg), so it can displace Mg from its compounds. Similarly, zinc (Zn) can displace iron (Fe), copper (Cu), and tin (Sn) from their compounds, but not vice versa.
