Which reaction will most likely take place based on the activity series? li &gt; k &gt; ba &gt; ca &gt; na &gt; mn &gt; zn &gt;
Ivenika [448]

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃

<h3>Activity Series</h3>

From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.

Let us look at each of the given options;

A) Ag + FeCl₃

From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.

B) Zn + CaO

Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.

C) Ba + Na₂CO₃

Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.

D) Cr + KNO₃

Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.

Complete question is;

Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt

A. Ag + FeCl₃

B. Zn + CaO

C. Ba + Na₂CO₃

D. Cr + KNO₃
