Question

Arrange Mg, H, and Ag with the most active first.

a) Ag, H, Mg
b) Mg, H, Ag
c) H, Ag, Mg
d) H, Mg, Ag

Answer 1

The most active metal and nonmetal in this list are Ag (silver) and H (hydrogen), respectively. Therefore, the most active element should be arranged first in the list. The correct arrangement is Mg, H, Ag.

Step-by-step explanation:

The most active metal and nonmetal in this list are Ag (silver) and H (hydrogen), respectively. Therefore, the most active element should be arranged first in the list. To determine the order, we compare the placements of Ag, H, and Mg in the activity series:

Ag - less active than H and Mg

H - more active than Ag and less active than Mg

Mg - most active among the three elements

Based on this comparison, the correct arrangement is Mg, H, Ag.
