Question

Rank the activity of aluminum with Ca, Cu,  Fe,  Mg,  Sn, Al, and  Zn.  

Rank from most reactive to least reactive. To rank items as equivalent, overlap them.

Answer 1

Ca>Mg>Al>Zn>Fe>Sn>Cu

Explanation

The above trend is based on activity series

Activity series is a seirial arrangement of metals according to highest reactivity to lowest reactivities of metals

if one metel is above the other metal in activity seires , the metal which is above is more reactive than the metal which is below

Activity series is usefull to determining the single displacement reactions and type of extraction of metals

For example

Zn is above Cu in activity series , Zn is more reactive than Cu

and Zn metal replace Cu from Copper salt solution
