Question 11 • Chemistry

Which reaction will most likely take place based on the activity series? Li is greater than cap k comma cap k is greater than Ba comma Ba is greater than Ca comma Ca is greater than Na comma Na is greater than Mn comma Mn is greater than Zn comma Zn is greater than Cr comma Cr is greater than Fe comma Fe is greater than Cd comma Cd is greater than Ni comma Ni is greater than cap h comma cap h is greater than Sb comma Sb is greater than Cu comma Cu is greater than Ag comma Ag is greater than Pd comma Pd is greater than Hg comma Hg is greater than Pt

Answer
A
Li plus ZnCO sub 3 rightarrow
B
Mn plus CaO rightarrow
C
Pt plus FeCl sub 3 rightarrow
D
Cu plus 2 KNO sub 3

Explanation

In a single-replacement reaction, a metal can replace another metal in a compound only if it is higher in the activity series. Lithium is above zinc, so Li can replace Zn in ZnCO₃. The other listed metals are below the metals they would need to replace, so those reactions are not expected to occur.
